PET and CT

Because PET measures metabolism, as opposed to MRI or CT, which image "structure", it can be superior to these modalities, particularly in separating tumor from benign lesions, and in differentiating malignant from non-malignant masses such as scar tissue formed from treatments like radiation therapy.

PET is often used in conjunction with a CT scan through "fusion" to give a full three-dimensional view of an organ and the location of cancer within that organ. The newest PET scanners are a combination of PET and CT devices that provide the important metabolic information from PET superimposed on the high-quality anatomic information from CT.
