Currently, to obtain a full-body scan, researchers must make a composite from serial scans, as well as information that comes from measuring temporal changes in radiotracer distribution, which can only be collected from one part of the body at a time.
The Tc-99m ECD SPECT/ CT revealed evidence of a large area of moderately decreased radiotracer distribution involving the superior, medial, and inferior frontal cortices of the right cerebral hemisphere.
Bone scan may be helpful in diagnosis, demonstrating increased radiotracer uptake within the region of the os peroneum.
However, the rapid clearance of radiotracer from the blood pool means that the patient must be bleeding at the time of injection.
After radiotracer injection, the patient is placed supine over a gamma camera that takes serial images of the radiotracer transit through the kidney, typically over a period of 20-30 minutes.
