Brain-computed tomography scan

All patients should have a brain computed tomography scan or magnetic resonance imaging scan to differentiate an ischemic stroke from a hemorrhagic stroke, as the treatment...

In the rabbit brain safety study using P(CPP-SA) 50 50 copolymer, even less of an inflammatory reaction was observed, and the polymer was essentially equivalent to Gelfoam [94]. In a similar brain biocompatibility study conducted in monkeys, no abnormalities were noted in the computer tomography scans and magnetic resonance images, nor in the blood chemistry or hematology evaluations [95]. No systemic effects of the implants were observed on histological examinations of any of the tissues tested [96]. No unexpected or untoward reactions to the treatments were observed. 

The most common type of PET scan uses a radioactive form of the sugar glucose to measure how the brain or body functions and to identify any tumor activity. CT (computed tomography) scans use X-rays to create a three-dimensional image of the body s structure. If your doctor will be ordering a standard PET or PET/CT scan of your body for examining your cancer, request that the scan be ordered with the specification that it also include a dedicated view of your... 

The most recent SPECT scan (single photon computed tomography of the brain) studies, by a Harvard School of Public Health physician and researcher, have shown that people with MCS have blood flow patterns in the brain that are different from those of healthy controls and from people with Chronic Fatigue Syndrome.4...

There is CT, for computerized tomography, a wedding of x-ray and the computer that scans a portion of, say, the brain by revolving an x-ray tube around the head, converting the pictures into a digital computer code to make high-resolution, three-dimensional video images accurate to. 9 millimeter. Differences in tissue density, between abnormal and normal tissue, are revealed fine details of bone structure appear clearly the location of tumors is pinpointed.
