Brain scintigraphy is a non-invasive procedure supporting the clinical diagnosis and it can be also easily performed and can exclude the negative and suspicious patients. For most studies, patients will be asked to drink as much fluid as possible, both before and after the nuclear bone scan procedure. General Nuclear Medicine Basics by Dr Justin G Peacock . The radioactive material collects in. The Belgian Society for Nuclear Medicine. Bone Scan Procedure. Most imaging tests for brain death rely on the absence of cerebral blood flow as a surrogate for brain death. Normal Scintigraphic Findings. A nuclear stress test uses a small amount of radioactive material (tracer) and an imaging machine to create pictures showing the blood flow to your heart. The test measures blood flow while you are at rest and during activity, showing areas with poor blood flow or damage in your heart. One of the radioactive tracers used is Tc99m-DTPA. They can be administered by a nuclear medicine technologist. A technician will do this through a vein in your arm or hand. X-rays show what your body looks like. A Magnetic resonance imaging (MRI) brain with gadolinium contrast was performed, which showed diffuse pachymeningeal enhancement [Figure 1].

There are several different types of brain perfusion scans. A PET scan shows how the brain and its tissues are working. Brain scans are used to detect dementia and other cerebral vascular disorders by giving the physician a view of the general perfusion (blood delivery) to the brain. Nuclear medicine scans can provide important information that you can't get from other types of testing. A nuclear stress test is one of several types of stress tests. Nuclear medicine diagnosis techniques include organ imaging, functional analysis and in vitro radioimmunoassay which can help physicians to visualize the morphology and function of an organ, tissue or some areas of the body. Look for "hot spots." The test results of a bone scan are considered normal when the radioactive dye is spread and absorbed evenly throughout your skeleton; however, a bone scan is considered abnormal when it shows darker colored "hot spots" in your bones. On the 143 brain 18F-FDG PET scans performed during this 3-month period, 53% of the scans were visually interpreted as normal, 21% as mildly to moderately or incompletely affected, and 26% as severely affected according to the COVID hypometabolic pattern.
