INTERVENTIONAL COMPUTED-TOMOGRAPHY AND MR-IMAGING IN THE HEAD AND NECK

Many modern surgical techniques have been developed to provide exposur e or visualization of the surgical field to perform definitive treatme nt. The actual therapeutic part of surgery is often a small fraction o f the procedure. In obtaining exposure, however, morbidity can ensue. This has led to newer techniques that use minimally invasive treatment s, thus substantially decreasing overall morbidity and patient costs. By providing physicians with visualization alternatives, MR imaging an d computed tomography, when combined with a therapeutic procedure, can reduce the morbidity of surgery.
