The tips specify conditions that imaging equipment must fulfill or exceed, including PET scanner and CT scanner pixel resolution, photon detection sensitivity, CT slice thickness, and scan time.
Because Each and every of those diverse anatomic spots has its have physiologic function(s) and techniques to surgical revision, Each individual area has a number of distinctive treatment pathways.

The CT may be used for that, if the lesion is likewise visualized in its visuals (it's not normally the situation when hypermetabolic lesions are usually not accompanied by anatomical changes).
