Prostatic high-resolution micro-ultrasound. an attractive step-forward in the management of prostate cancer patients

Prostatic high resolution micro-ultrasound (MUS) was first described by Pavlovich et al. in 2014 [1]. Thanks to scanners operating at high frequency (29 MHz) and the resulting real-time spatial resolution up to 70 microns (near 300% higher than existing platforms) it allows to better evaluate the microstructures and tissue planes. Consequently, MUS is capable of highlighting the alterations of the prostatic histology that are typically associated with high-grade prostate cancer (PCa) such as loss of normal acinar lumen and tighter cellular packing.
