ABSTRACT
Multiparametric MRI—the most accurate imaging technique for detection of prostate cancer—has transformed the landscape
of prostate cancer diagnosis by enabling targeted biopsies. In a targeted biopsy, tissue samples are obtained from suspicious regions
identified at prebiopsy diagnostic MRI. The authors briefly compare the different strategies available for targeting an MRIvisible
suspicious lesion, followed by a step-by-step description of the direct MRI-guided in-bore approach and an illustrated
review of its application in challenging clinical scenarios. In this technique, direct visualization of the needle, needle guide, and
needle trajectory during the procedure provides a precise and versatile strategy to accurately sample suspicious lesions, improving
detection of clinically significant cancers. |
