✦ Synopsis

Abstract

A simple method is described that corrects for the intensity inhomogeneity experienced when using endorectal surface coils in prostate imaging. The method uses a series of proton‐density‐weighted images, which are acquired to demonstrate the sensitivity profile of the coil and used to correct T2‐weighted images acquired in the same plane. The results demonstrate improved image uniformity and visualization of prostatic anatomy.

## Abstract We have designed a solid endorectal receiver coil for MRI of the prostate. The coil provided an improved signal‐to‐noise ratio up to 5 cm from its surface when compared with a standard pelvic phased array.
