Gadolinium-enhanced Magnetic Resonance Angiography in the Planning of Supratentorial Glioma Surgery

Abstract

The utility of gadolinium (Gd)-enhanced magnetic resonance (MR) angiography in the planning of supratentorial glioma surgery was evaluated. MR angiograms of the arterial and venous anatomy visualized the anatomical relationship of the main arteries to the tumor, especially on three-dimensional images. Combination with data from surface anatomical images allowed the tumor location to be determined preoperatively. Gd-enhanced MR angiography can be used non-invasively prior to tumor surgery to ascertain the spatial relationship of the vessels to the tumor mass.
