Grayscale transrectal ultrasonographic prostate biopsy using local anesthesia remains the standard approach to the definitive diagnosis of prostate cancer. Prostate cancer has a new standard of care in MRI-guided fusion biopsy with transrectal ultrasound. The samples, or "cores," are put onto glass slides to be examined under a microscope for signs of cancer. MRI-targeted biopsy, whether using any of the three options of cognitive fusion, MRI-ultrasound fusion software, or in-bore MRI-guided biopsy, can also be performed via either transrectal or transperineal approaches. The Number of Cores Removed Many different theories exist as to the “best” way to “sample” the prostate … The way that prostate biopsy samples are handled varies among hospitals. In the transrectal approach, the biopsy needle is passed through a needle guide attached to ultrasound, and then through the rectal wall into the prostate under guidance.

While early studies of transrectal ultrasound (TRUS) proposed a hyperechoic appearance for prostate cancer (Resnick 1978, Peeling 1979), improvement in probe technology and an increase in ultrasound frequency utilized in transrectal imaging indicated that prostate cancer was hypoechoic (Frentzel-Beyne 1983).
