Implication

Comparative imaging study demonstrates high-resolution MRI visualization of pelvic fascias in rectal cancer, highlighting its value for surgical planning.

Key Points

To describe the radiologic appearance of key anatomic structures, particularly fascial planes and nerve plexuses, relevant to surgical planes in total mesorectal excision of the rectum.
Performed high-spatial-resolution T2-weighted MRI using a 1.5-T system on cadaveric pelvic sections and in vivo patients prior to total mesorectal excision surgery.
Compared anatomic dissections of sagittally sectioned hemipelves directly with in vivo MR images to define visual criteria for anterior resection landmarks.
High-resolution MRI consistently depicted key surgical boundaries, including the mesorectal fascia, presacral fascia, peritoneal reflection, and Denonvilliers' fascia.
T2-weighted fast spin-echo imaging provided sufficient contrast resolution to resolve pelvic structures as small as 1–2 mm, clearly displaying the inferior hypogastric nerve plexus.
