Abstract:
Prostate cancer is most commonly imaged through a combination of magnetic resonance imaging, x-ray computed tomography, and 99mTc-methylene diphosphonate bone scan. These conventional imaging modalities, however, suffer from limited sensitivity and specificity for the detection of disease. This can lead to disease understaging and the improper selection of treatment. To address this problem, a variety of novel radiotracers for positron emission tomography (PET) imaging have been developed. This includes agents that accumulate on the basis of alterations in cellular metabolism (eg, 11C-choline and 18F-FACBC) as well as those that bind to specific proteins (eg, 68Ga-PSMA-11, 18F-DCFPyL, 68Ga-RM2, and 18F-DHT). In this review, we examine the performance characteristics of these new PET radiotracers for imaging prostate cancer and discuss ways in which PET imaging can offer more precise clinical information to patients and providers.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
