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 Shandong, China.
"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.
