3T MRI can accurately stage, and help surgeons plan sphincter-sparing
surgery in patients with rectal cancer, according to a recent study
conducted by researchers at Qilu Hospital of Shandong University in
"Recently, MRI has been increasingly accepted by radiologists,
surgeons and patients to image the rectum because of its superior soft
tissue contrast and multi-planar capability," said Chuanfu Li, MD, lead
author of the study. "Most rectal MRI studies have used field strength
of 1.5 Tesla or less. Only two recent studies focus on 3T MRI for
diagnosing and staging rectal cancer. "No standard protocol is
available for 3T MRI of the rectum, which may cause inconsistent
diagnostic accuracy among institutions. The purpose of this study was
to evaluate the image quality of various 3T MR sequences for
preoperative staging and planning of sphincter sparing rectal cancer
resection," he said.
The study included 39 patients (23 men, 15 women), who underwent 3T
MRI. According to the study, rectal carcinoma was identified on MRI and
confirmed histologically in all 38 (should this be 39?) patients. The
study showed that MRI findings correctly identified 31 of 32 resectable
cases (96.9%), and sphincter-sparing approaches were accurately chosen
on the basis of the MRI findings.
"In addition to accurate tumor staging, MRI contributes to surgical
planning by showing the relationship of tumor to the sphincter and
levator ani muscles on good quality coronal and sagittal images," said
Dr. Li. "This technique can give the surgeons a higher level of
confidence and ," he said.
The study appears in a recent issue of the American Journal of Roentgenology.
