plaques(Bright Focus). To diagnose Alzheimer’s disease, a PET scan may be performed to view images of the brain. Images from a PET scan of a brain unaffected by Alzheimer’s disease show a high contrast of colors, where the brain has high neural activity (Chabner, 2017). A person with Alzheimer’s disease will have an image from a PET scan that shows low neural activity (mainly blue and purple colors on the PET scan image). CT and MRI scans are also available to produce images of the brain to diagnose

There are 4 different types of Chiari malformations. Type 1 is the most common and occurs when the cerebellar tonsil is found below the forman magnum; usually affecting older children or adults and is the only type of malformation that can be acquired. Type II involves both the brainstem and cerebellum below the forman magnum, this type is usually associated with other diseases such as spina bifida and myelomeningocele. This is usually found in children and this type is responsible for the name

The department that I am shadowing is the radiology, or imaging services, department where all x-rays, CT scans, MRI, and GI scans are taken and processed. There are many programs that one can take to become educated in this field, one of the bigger more heard of programs in Missouri is at St. Louis community college. This is a 73-75 credit hour program that takes three years to complete. The total cost for a Missouri resident is 7,616 dollars, about 101 dollars per credit hour, the cost goes

aortic aneurysms may be diagnosed by echocardiogram, and this technique is often used to screen family members of those with thoracic aortic aneurysm. • Computerized tomography (CT) scan-This painless test can provide your doctor with clear images of your aorta, and it can detect the size and shape of an aneurysm. During a CT scan, you lie on a table inside a doughnut-shaped machine. • Magnetic resonance angiography (MRA)-An MRA is a painless imaging test that may be used to diagnose an aneurysm and

Two New Approaches on the Horizon for Mesothelioma Treatment Mayo Clinic researchers and theirs teams are targeting pleural mesothelioma with two very different approaches. One tactic uses a converted virus to carry radioactive iodine to targeted cells. The other examines a new use for an existing drug. The reason for the studies? Mesothelioma cases have been on the rise in recent years, especially in Minnesota's northern Iron Range region, where the mining of taconite poses a significant occupational

emission tomography scan also knows as a PET scan. Radiation is also used as a therapy through the use of a treatment using chemotherapy. There is also a form of treatment called Radiation therapy that is used as a medical use. The journey from using radiation to detect if the body has cancer, to the treatment types of therapy using radiation evolve into the medical uses of radiation. We will explore these three subject areas and give you an insight to the uses and benefits of them PET scan, Chemotherapy

In the maxilla, resorption following tooth extraction occurs mainly within the first 3-12 months post-operatively

Introduction/Background High resolution computed tomography (HRCT) is an imaging method that provides more detail than either chest radiography or conventional CT scanning 1 Compared to other diagnostic tests, like chest radiography and lung function test, HRCT can be more sensitive and specific in the diagnosis of diffuse lung diseases and detecting abnormalities at an early stage. HRCT can more accurately assess the pattern and distribution of diffuse lung disease, and to a lesser degree, assess

(SPECT-CT) as hybrid imaging is used to change of planar imaging for cardiac and brain scanning and as an adjunct to planar scintigraphy in many other anatomy, such as bone, infection and tumour

Abstract: Pneumomediastinum is a pathologic condition characterized by the presence of air within the mediastinum and within deep neck spaces. It can be further categorized as spontaneous pneumomediastinum or secondary pneumomediastinum. Spontaneous pneumomediastinum is a rare clinical entity seen without any precipitating factors. On the other hand, secondary pneumomediastinum is due to disruption of the aeordigestive tract, typically from previous surgery, trauma, severe retching, or foreign body
