Endorectal coil magnetic resonance imaging

Endorectal coil magnetic resonance imaging

Endorectal coil magnetic resonance imaging or endorectal coil MRI is a type of medical imaging in which MRI is used in conjunction with a coil placed into the rectum in order to obtain high quality images of the area surrounding the rectum. [cite journal | author=Hricak H, White S, Vigneron D, Kurhanewicz J, Kosco A, Levin D, Weiss J, Narayan P, Carroll PR. | title=Carcinoma of the prostate gland: MR imaging with pelvic phased-array coils versus integrated endorectal-pelvic phased-array coils. | journal=Radiology | volume=193 | issue=3 | year=1994| pages=703–709 | pmid=7972810] The technique has demonstrated higher accuracy than other modalities in assessing seminal vesicle invasion and extra-capsular extension (ECE) of prostate cancer (96% and 81% respectively). Endorectal coil MRI is useful for determining the extent of spread and local invasion of cancers of the prostate, rectum, and anus.

Similar coils may be used vaginally for evaluating cervical cancer.
