Compared with the standard transrectal ultrasound-guided sextant biopsy, MRI-targeted biopsies detect more intermediate/high-risk cancer using fewer biopsy cores and reduce overdetection of low-risk cancer.
In order to increase the cancer detection rate of prostate biopsy, various schemes have been applied in time such as sextant biopsy, extended biopsy and saturation biopsy (9).

The biopsy procedure was completed as a sextant biopsy in left lateral decubitus position, using a 22-gauge needle accompanied by transrectal ultrasound.

Thus, a prostate cancer diagnosis is typically made through TRUS-guided sextant biopsy and histopathological examination.
