It is relatively easy to distinguish PZ from TZ on transverse views so that simultaneous images of both transverse and sagittal images make far lateral biopsy easy. For the sagittal images only, after identifying the center of prostate such as the line of urethra, then, slowly rotate ultrasound probe to the lateral part, so that far lateral PZ would be identified just after disappearing from TZ. For patients with middle to large prostate, far lateral PZ on sagittal images may sometimes represent only the mid-base of the prostate. To obtain biopsies from the far-lateral part of PZ at the apex, we need to slightly rotate to the center.
