Endorectal ultrasound (ERUS) since its introduction over 30 years ago has refined the preoperative staging of rectal cancer. Initially used to image the prostate and rectum the primitive 4 megahertz (MHz) transducers have progressed to higher frequency probes with markedly better resolution and most recently with the routine addition of three-dimensional (3D) machines. This chapter addresses the applications of ERUS in the preoperative staging of rectal cancer and its place alongside other modalities such as MRI.
