MR-guided biopsy of the prostate: Comparison of diagnostic specimen quality with 18G and 16G biopsy needles

16G biopsy needles do not provide a relevant diagnostic advantage over 18G needles in MRGB. Therefore, use of 18G needles is not discouraged and may even be preferred as it is not expected to result in a relevant degradation of specimen quality or compromise in prostate cancer detection rate.
