Radiological Staging and History of Endorectal Sonography,As new imaging techniques became available they were used to stage rectal cancer.

Anatomy,Endorectal sonography is being used to assess a wide range of abnormal rectal conditions. So that the images can be interpreted accurately, the normal sonographic anatomy must first be described.

We have used Toshiba and Aloka linear scanning devices but have found image interpretation and manipulation of the probes within the rectum easier with the radial device. There are also a few images using a 12 MHz prototype Olympus ultrasound colonoscope.
