PET scans measure metabolic processes by sending gamma rays into the body that detect a radiopharmaceutical (or tracer) that was introduced into the body. With the aid of a CT x-ray scan, this provides a 3D image. The High Definition of the Siemens Biograph TruePoint PET/64 CT requires a lower dose than a typical scan, as well as decreased scan time.
This machine has 64 slice technology, whereas most facilities only have 16-slice technology. This means the slices of the image are thinner and therefore more precise than a typical scan because the area of concern is better localized. This helps your doctor make a more accurate diagnosis.
