Evaluation of B-mode ultrasound as a means of improving radium dosimetry in the treatment of gynecologic cancer.

The radiation dose to the base of the bladder and anterior rectal wall during radium applications for gynecologic cancer is a function of the distances between the source and the bladder and rectum. Precise measurement of these distances depends on a number of factors and cannot be obtained with current radiographic localization techniques. B-mode ultrasound is useful as a means of supplementing available information. While it is not necessarily more accurate than standard radiographs, it offers a three-dimensional appreciation of pelvic anatomy and does appear to be more accurate than transverse axial tomography.
