Identification And Characterization

Ten patients with native intracranial dural arteriovenous fistulae (DAVF) demonstrated by arteriography underwent MR imaging and phase contrast MR angiography before treatment. The DAVFs were of type I (n=2), IIa (n=l), II a+b (n? 3), and TV (n=4). Joint review of the arteriography, MR imaging and MR angiography hard copies was performed by two observers. MR imaging showed intracerebral hemorrhage in 2 patients and diffuse or focal white matter edema in 2. Focal venous ectasias in 4 patients with type TV DAVF and dilated cortical vessels in 6 patients were recognized on MR images. MR angiography enabled identification of the DAVF nidus in 2 patients, hypertrophic feeding vessels in 5 patients and cortical dilated veins in 8 patients. Steno-occlusive alterations of the dural venous sinuses in 6 patients were readily demonstrated on MR angiography. Moreover, in 3 patients with type II a+b DAVFs, reconstruction of image phase of MR angiography allowed identification of flow revers al in the dural sinuses near the DAVF. Phase contrast MR angiography is a useful complement to MR imaging for identification and characterization of intracranial DAVF.
