human body. This new technology through the work of many scientists was evolved into the MRI scanners used by doctors throughout the world today. This invention has changed the face of modern medicine but, unfortunately in The United States, MRIs scans cost a more, on average, than any other country in the world, and are being misused at a staggering rate. In order to fix these issues, health care professionals and consumers of MRIs must step

Situs Inversus According to the Centers for Disease Control and Prevention there are approximately three million babies born in the United States each year (Martin et al.). While there is always risk that a baby could have any number of health conditions, one rarely occurring condition is situs inversus. “Situs” refers to the position of an organ, with situs solitus being the ordinary arrangement of organs (Dictionary). Situs inversus is when the organs in the chest and abdomen are mirrored, or opposite

the uterus. The physical signs of her scoliosis included tilted, uneven shoulders, with one shoulder blade protruding more than the other and an overall appearance of leaning to the side. Her diagnosis was confirmed with a Computer Tomography scan (CT Scan). Other methods which can be used include

intracranial pressure is elevated, as it may lead to brain herniation. If someone is at risk for either a mass or raised ICP (recent head injury, a known immune system problem, localizing neuroloical signs, or evidence on examination of a raised ICP), a CT or MRI scan is recommended prior to the lumbar

The blood test can validate the number of abnormal cells that are present, similar to a bone marrow biopsy, while a CT scan can confirm the swelling of lymph nodes or if the liver and/or spleen are enlarged. Even though WM and Multiple Myeloma are similar, they can be verified via x-ray. Blood test can be used to determine if it is WM. The estimated normal range for Igm

A positive D-dimer test would be expected with this patient. Arterial blood gases may show that the patient is hypoxic and has respiratory alkalosis (McCance & Huether, 2014). A CT scan may show an affected artery that has become enlarged. Hemotocrit may be high causing the blood to not be able to thicken like it would normally. PTT and INR could be low and also tell the provider how capable the body’s blood clotting capabilities

opinion when it comes to relying on bone scan and FDG PET scan in differentiating between osteopoikilosis and bone metastases. Unfortunately, there is a problem of overreliance on imaging

into the spinal canal. An MRI is often used to diagnose Chiari malformation. Since this pain less test is harmless, it can be done more than once, and explain progress with treatments [10]. Computerized Tomography (CT) uses X-rays to obtain cross-sectional images of your body. A CT scan can help to reveal brain tumors, brain damage, bone and blood vessel abnormalities, and other conditions [10]. When taking these tests, doctors look for the results of defining the size of the cerebral ventricles

Coronary CT angiography on revascularized patients: coronary stenting Recently, coronary CT angiography has been increasingly used for assessment of coronary stent patency or restenosis. However, imaging of coronary stents by multislice CT is more difficult than imaging of a native coronary artery. This is because of the presence of metal within the stents which can cause artifacts interfering with the interpretation of lumen patency. While the accuracy of stent lumen analysis was low or modest with

COMMON PRESENTATIONS OF GASTRIC GASTROINTESTINAL STROMAL TUMOURS (GIST) Introduction Gastrointestinal stromal tumours (GIST) are rare tumours of the gastrointestinal tract. However, from another perspective, they are also considered to constitute the most common mesenchymal tumours of the gastrointestinal tract. These tumours are believed to arise from the interstitial cells of Cajal, the pacemaker cell of the gastrointestinal tract 1. In the past, these mesenchymal tumors were classified as
