24 May 2017 To determine the diagnostic accuracy of, and the concordance between, the MRI pathway and TRUS-guided biopsy approach for detecting clinically significant prostate cancer in men with a suspicion of prostate cancer, using template-guided biopsy as the reference standard. To investigate what clinical
In fact, a side-by-side comparison of TRUS versus MRI-guided targeted biopsy that was conducted as a prospective, investigator-blinded study demonstrated that MRI-guided biopsy improved detection of significant prostate cancer by 17.7%, and decreased the diagnosis of insignificant or low-risk disease by 89.4%.
7 Oct 2011 Unlike imaging-guided biopsy procedures performed in many other organs, transrectal US–guided prostate biopsy is not a targeted biopsy procedure, because most prostate tumors are not visualized on images or are indistinguishable from normal prostatic tissue and benign prostatic hyperplasia. .
25 Apr 2016 This topic addresses indications for, preparation for, and performance of prostate biopsy—in particular, transrectal ultrasonography (TRUS)-guided biopsy of the prostate gland. Although a number of different methods may be used to perform TRUS-guided prostate biopsy, the authors find that those

Biopsies are most commonly performed under ultrasound guidance. During the procedure, a special biopsy needle is inserted into the prostate gland through the wall of the rectum to remove several small samples of tissue for pathologic analysis. This method is known as transrectal ultrasound (TRUS) guided biopsy.
17 Oct 2010
Transrectal ultrasound–guided biopsy is considered the standard approach for prostate biopsy and is most commonly performed on an outpatient with a positive screening for prostate cancer. Nowadays, with the MRI capacity for depicting abnormal areas of the prostate, is possible to obtain targeted sampling of prostate
7 Oct 2011 Transrectal ultrasonography (US)–guided biopsy is the standard approach for histopathologic diagnosis of prostate cancer. However, this technique has multiple limitations owing to the operator's inability in most cases to directly visualize and target prostate lesions. Magnetic resonance (MR) imaging of the
26 Feb 2014 Prior to imaging methods, the prostate biopsy was guided by direct palpation. The use of TRUS began in the early 1970s with advent of ultrasound, and the original sextant biopsy scheme (total of six cores from the base, middle, and apex bilaterally) improved detection over digital guidance (8).
