TUESDAY, Sept. 28, 2004 (HealthDayNews) -- Using magnetic resonance imaging (MRI) during brain tumor surgery helps doctors remove all the residual cancer in one operation, says a German study in the October issue of Radiology.

Without the aid of MRI guidance during surgery, surgeons may miss small parts of the tumor, which can lead to the need for repeated surgery, surveillance or further treatment.

"Imaging during surgery provides intraoperative quality control. It presents valuable information during the procedure that allows the surgeon an opportunity to adjust the strategy," study author Dr. Christopher Nimsky, of the University Erlangen-Nurnberg, said in a prepared statement.

In tests with 200 brain tumor patients, intraoperative MRI influenced strategy during surgery in 27.5 percent of the cases. In most of those cases, it identified additional cancerous tissue that needed to be removed from the brain.
