Answer

As stated above, imaging studies, including standard and color Doppler ultrasonography, computed tomography (CT) scanning, and magnetic resonance imaging (MRI) of the prostate, None of these have  proven beneficial in identifying the presence of HGPIN or ASAP.

Color Doppler ultrasonography can reveal abnormal areas in the prostate that have increased vascularity. Some prostate cancers can be identified with this technique, but areas of inflammation may have the same visual characteristics. In addition, not all cancers have enough vascularity to permit identification. The vascular changes caused by HGPIN and ASAP are not sufficient for identification.

MRI with spectroscopy may reveal areas with biochemical abnormalities suggestive of cancer, but HGPIN and ASAP are more difficult to find, because they are small and multifocal and are often located at the periphery of a cancer.
