ABSTRACT
Modern MR systems conventionally have multielement body coils for imaging the pelvis. An array or matrix of coil elements positioned anteriorly are matched with a paired matrix positioned posteriorly or with the matrix of coils in the spine coil. Endorectal coils can provide an increase in signal-to-noise ratio for small FOV applications, for instance in prostate imaging, but physical tissue distortion of the wall of the rectum and signal flaring directly adjacent to the coil can impact on image interpretation.
