"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 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.

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
Biochips have been developed at TU Wien (Vienna), on which tissue can be produced and examined. This allows supplying the tissue with different substances in a very controlled way.
Cultivating human cells in the Petri dish is not a big challenge today. Producing artificial tissue, however, permeated by fine blood vessels, is a much more...
