The role of Magnetic Resonance Imaging (MRI) in Diagnoses of Pituitary Gland The pituitary gland is an important part of the body because it controls several hormonal glands such as adrenals and the thyroid. The gland is a nearly the size of a pea and has two parts referred to as the lobes (Maya & Pressman, 2010). The front part is the anterior pituitary while the back part is the posterior pituitary. The pituitary gland is part of a bony hollow called the pituitary fossa behind the bridge of the nose and below the brain’s base near the optic nerves. Maya and Pressman (2010) add that the pituitary gland is the most important part of the system because it produces hormones controlling the functions of other endocrine glands. The most common problem occurring in the pituitary gland is the development of a benign growth or tumor. The tumor causes the gland to secrete excess hormone, blocks its production or causes it to malfunction. Other causes of pituitary disorders include traumatic brain injury and pituitary infarction. Although pituitary disorder are able to alter quality of a person’s life significantly, medical or surgical treatment is available where efficient diagnosis is made. The present study investigates the role of imaging modalities in the evaluation of pituitary gland disorders. Particular emphasis is laid on the role of Magnetic Resonance Imaging (MRI) in diagnosing the pituitary gland.
Anatomy of the pituitary gland The sellar region of the brain is anatomically complex being bounded by sinus arteroinferiorly, the brainstem posterioly, the dorsum sella, the hypothalamic sellae, the suprasella, and the cavernous sinuses laterally (Drouin, 2010). The hypothelamus consists of a layer of tissue that extends from the…...

British Journal of Radiology, 83(988), 79. With this article, it describes the pathology and etiology in the middle age with two diagnoses for tendinopathy, and colcinosis with pathology on collateral ligaments in the middle age. It describes the calcification within the fibular collateral ligament. It pertains to a 52-year-old man that was presented with tenderness and pain over the lateral aspect of the left knee. According to the patient, it occurred from a fall on the stairs and the twisting of the left knee. Some of the tests that were taken such as with a tomography showed signs of myofascial edema in the lateral soft tissue. The differential diagnosis stated that it could exclude acute ligamentous injury, fracture or infection and also after the magnetic resonance imaging (MRI) it also excluded avulsion fracture. After concluding that the oral cortex was intact with a smooth contour their diagnosis was Periarticular calcification that could be determined from the MRI and CT scans. The other diagnosis was hydroxyapatite depositon with confirmed calcification in the fibular collateral. My concern with both of these diagnosis’s would be that if both found the same thing in the testing how can there be two different conclusions on what is occurring in the gentlemen’s knee .

Comments on Central Nervous System and Radiological Anatomy

...COMMENTS ON CENTRAL NERVOUS SYSTEM AND RADIOLOGICAL ANATOMY Radiological Anatomy Radiological anatomy is a medical specialty that employs the use of imaging to both diagnose and treat disease visualised within the human body. It explores various tissue densities to be able to determine structures. It could either be invasive or non-invasive. Radiologists use an array of imaging techniques which include: • Conventional radiography (X-ray) • Ultrasound • Computerized Tomography • Magnetic Resonance Imaging • Interventional Radiology • Radiation Therapy The acquisition of medical imaging is usually carried out by the radiographer or radiologic technologist. The radiologist then interprets or "reads" the images and produces a report of their findings and impression or diagnosis. Central Nervous System The nervous system is organized into two parts: the central nervous system, which consists of the brain and the spinal cord, and the peripheral nervous system, which connects the central nervous system to the rest of the body. In the central nervous system, the brain and spinal cord are the main centres where communication of nervous information occur. Both the brain and spinal cord are covered with a system of membranes, called meninges and are suspended in the cerebrospinal fluid; they are further protected by the bones of the skull and the vertebral column. The central nervous system is composed of large numbers of......

Medical Imaging

...R Medical Imaging Radiation The impact of technology in today’s society has increased overtime. Different forms of technology have changed dramatically over the years, the way we now use technology is different to the way it was used before. Everything we do in our days has technology involved in it whether it is in school, work, health and work. People’s view towards the amount of technology that is now involved in our daily lives is different from others and its consequences. Some it’s good but others argue saying it ruins life’s and our perspective towards things. Medical imaging has effects on radiation in the human body which is brought up by the change of technology. Medical imaging such as CT scans, X-rays, ultra sounds and MRI scans which are used in procedures to view the different types of areas in the human body and provide important information for specialists. These procedures present both benefits and risks of using medical imaging; they have helped improve diagnoses and treatments of different types of medical issues. Before there was not much technology in our society meaning there were not such machines, now that technology has grown and brought different type of medical imaging doctors are now able to dictate and have a open understanding of the diagnoses. Studies and researched information have shown that medical imaging is causing radiation to our body ‘The Research Established of the Australian Atomic Energy......

Purchasing an Mri

...investigate the possibility of new capital equipment; they need to know that this equipment will increase the delivery of services. This hospital would like to invest in a new updated magnetic resonance imaging (MRI) machine. The current MRI machine is over 20 years old, is unable to acquire any new information, and is costing the radiology department more in maintenance to keep it running than it would cost to purchase a new one. Radiology has requested a new Signa HDxt 3.OT MRI system as a capital budget item. The Signa HDxt3.OT delivers high-density coils and has great “tissue characterization and artifice reduction, high efficiency with a detachable table, so a technologist can remove a patient in less than 30 seconds” (Signa HDxt 3.OT, 2013, p. 1). The initial cost of the MRI machine is $1.2 million. The cost to update the system over the next few years is approximately $250,000 per year, which includes the education training information, cost of power, and maintenance fee (Signa HDxt 3.OT, 2013). The x-ray department overhead will include scheduling, billing, nursing support, office equipment, and the salary of the MRI radiology technician, which is around $65,000 a year. The cost per year to operate the new MRI machine would be around $400,000 (Gayler 2007). Because the old MRI machine is larger, we will incur construction costs to update the electrical panels. Heating/air conditioning and ventilation may need to be redone, and new......

...gene turns on or off to produce a specific protein. Scientists believe epigenetics play a major role in mental disorders and the effects of medications. Some, but not all mutations and epigenetic changes can be passed on to future generations. Further understanding of genes and epigenetics may one day lead to genetic testing for people at risk for mental disorders. This could greatly help in early detection, more tailored treatments, and possibly prevention of such illnesses. The Working Brain Neurotransmitters Everything we do relies on neurons communicating with one another. Electrical impulses and chemical signals carrying messages across different parts of the brain and between the brain and the rest of the nervous system. When a neuron is activated a small difference in electrical charge occurs. This unbalanced charge is called an action potential and is caused by the concentration of ions (atoms or molecules with unbalanced charges) across the cell membrane. The action potential travels very quickly along the axon, like when a line of dominoes falls. When the action potential reaches the end of an axon, most neurons release a chemical message (a neurotransmitter) which crosses the synapse and binds to receptors on the receiving neuron's dendrites and starts the process over again. At the end of the line, a neurotransmitter may stimulate a different kind of cell (like a gland cell), or may trigger a new chain of messages. Neurotransmitters send chemical messages......

Mri(Magnetic Resonance Imaging)

...MRI(Magnetic resonance imaging) MRI is a instrument commonly used in a medical diagnostics. MRI stands for magnetic resonance imaging, it is a test that uses a magnetic field and pulses of radio wave energy to make pictures of organs and structures inside the body. A MRI can give different information about structures in the body than can be seen with an X-ray, ultrasound, or computed tomography (CT) scan. It measures the water content of tissues within the body, which is processed by the computer, creating a black and white image. A MRI can produce a highly detailed image, showing even the smallest abnormality. A MRI uses strong magnetic fields and radio frequency waves to create images of the human body. A dye containing gadolinium, has magnetic properties that are used during the procedure. It will then circulate through the blood stream and absorbed into certain tissues, that stand out on the scan. The wavelength is somewhere between 4.6m and 3.5m. MRI is the best type of imaging to diagnose most types of brain tumors. They use magnetic fields and radio waves, rather than X-rays, and computers to create detailed pictures of the brain. MRIs show “slices” of the brain that can be used to create a three-dimensional picture of a tumor. The contrast dye is used to enhance the images. When having an MRI done, the area of the body being studied is placed inside a special machine that contains the strong magnet.The standard MRI machine looks like a long cylinder with a......

Endocrine Glands

...Endocrine glands hypothalamus: The hypothalamus is a part of the brain located superior and anterior to the brain stem and inferior to the thalamus. It helps many different functions in the nervous system, and is also responsible for the direct control of the endocrine system through the pituitary gland. The hypothalamus contains special cells called neurosecretory cells—neurons that secrete Pituitary gland: The pituitary gland, also known as the hypophysis, is a small pea-sized lump of tissue connected to the inferior portion of the hypothalamus of the brain. Many blood vessels surround the pituitary gland to carry the hormones it releases throughout the body. Situated in a small depression in the sphenoid bone called the sella turcica, the pituitary gland is actually made of 2 completely separate structures: the posterior and anterior pituitary Anterior Pituitary: the true glandular part of the pituitary gland. The function of the anterior pituitary gland is controlled by the releasing and inhibiting hormones of the hypothalamus. The anterior pituitary produces 6 important hormones: Thyroid gland: The thyroid gland is a butterfly-shaped gland located at the base of the neck and wrapped around the lateral sides of the trachea. The thyroid gland produces 3 major hormones: Parathyroid gland: are 4 small masses of glandular tissue found on the posterior side of the thyroid gland. The parathyroid glands produce the hormone parathyroid hormone (PTH),......

The Role of Technology in Rising Health Care Costs. What Should or Shouldn’t Be Done.

...The Role of Technology in Rising Health Care Costs. What should or shouldn’t be done. Neha Para, MPH Student 5453-001 US Health Care System University of Oklahoma Health Sciences Center December 8, 2010 Abstract Health care costs are a longstanding concern to policymakers. For years, health care spending has been rising faster than the rate of economic growth, raising the question of what factors are responsible for rising health care costs. This paper explores published articles that report results from research conducted on technological innovations in health care and its relation to rising health care costs. The cost increases have a significant effect on households, businesses, and government programs. Health care experts indicates the development and diffusion of medical technology as primary factors in explaining the persistent difference between health spending and overall economic growth, with some arguing that new medical technology may account for about one-half or more of real long-term spending growth. Rising health care expenditures lead to the question of whether we are getting value for the money we spend. On an average, increases in medical spending as a result of advances in medical care have provided reasonable value. An alternative viewpoint holds that although new technologies represent medical advances, they are prone to overuse and thereby excess cost. Most of the suggestions to slow the growth in new medical technology in the U.S. focus......

Magnetic Nanoparticle in Cancer Therapy

...Summary Magnetic nanoparticles have allowed for many breakthroughs in cancer therapy. They are currently being implemented with cancer diagnostics, which allows healthcare professionals to image where cancerous areas reside in the body. For example, magnetic nanoparticle have been utilized in conjunction with MRI scans to greatly increase the image contrast, leading to the detection of small and otherwise undetectable prostate cancer metastases. Additionally, nanoparticles are being used as a physical means of destroying tumorous tissue by the use of Magnetic Nanoparticle Hyperthermia. This technology uses the power of magnets to oscillate iron oxide magnetic nanoparticles to create heat in the form of kinetic energy and has shown to drastically reduce the size of brain tumors when compared to patients who have no treatment at all. Beyond their use as diagnostics and physical tools to destroy cancerous tumors, magnetic nanoparticles are also used as a delivery agent for gene therapy. For example, magnetic nanoparticles have shown to increase the half life of the various biological matter such as DNA and RNA so that it can reach the intended target before the body’s immune response destroys the magnetic gene delivery system. In the future, research will be focused on pharmacokinetics of the nanoparticles, ensuring the nanoparticles can stay in the body for longer periods of time and that the body reacts in a positive manner to the magnetic......

Diagnostic Imaging Modalities

...Diagnostic Imaging Modalities Skeletal metastases can be evaluated by four clinical imaging modalities: plain film radiography, computed tomography (CT), magnetic resonance imaging (MRI), and skeletal scintigraphy. Plain Film Radiography Plain film radiographs are commonly used to evaluate symptomatic areas and to confirm findings seen with other imaging modalities. Because of its poor sensitivity (ie, 44% to 50% less sensitive than scintigraphy in detecting breast cancer metastases[3]), it is generally not used as a screening method.[3–5] Considerable bone destruction must be present before a bone metastasis is evident radiographically. An estimated 30% to 75% reduction in bone density is required for a lesion to be visualized on radiographs.[1] Moreover, the radiographic bone survey remains useful in the event of a "skeletal emergency," such as an impending pathological fracture, particularly of weight-bearing bones (Fig 2A). Radiography is invaluable for assessing the extent of cortical compromise and the risk of pathological fracture in tubular bones.[6] For example, lytic lesions that destroy 50% or more of the diaphyseal cortex can result in a 60% to 90% reduction in bone strength, significantly increasing the risk of fracture.[6] Radiographs are recommended for patients with symptoms of pain or tenderness that might be related to a weight-bearing bone (eg, femur or tibia).[6] The radiographic bone survey, however, remains important in staging of multiple myeloma due...

Endocrine Glands

...When people talk about glands, what do they mean? The answer is many different things. Glands are important organs, you have a variety of them all over your body, and though many of them are small, each produces something important. Some glands make something that is released from the body — like saliva, sweat, or tears. And if you're a girl, the mammary glands in your breasts could someday make breast milk to feed a baby. Other glands release hormones (say: hor-mones), which are substances inside your body that tell it how to work and how to grow. Glands that do this are part of the endocrine (say: en-doh-krin) system. Puberty — body changes that turn a kid into an adult — depend on the endocrine system. Still other things that we call "glands" are part of your immune (say: ih-myoon) system. They release substances that help you fight off illnesses and, if you are sick, help you get better. When you have a bad cold and your neck glands are swollen, that is your immune system in action. Exocrine glands are a type of ductal glands that secrete their products (including digestive enzymes, and some hormone chemical messengers) into ducts that lead directly into the external environment. They are the counterparts to endocrine glands, which secrete their products (hormones) directly into the bloodstream (ductless glands) or release hormones (paracrines) that affect only target cells nearby the release site. The hypothalamus (from Greek ὑπό = under and θάλαμος = room,......
