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.
