[Diagnosis for dural arteriovenous fistulas based upon MR angiography].
Diagnosis of dural arteriovenous fistulas (DAVFs) has been traditionally based on cerebral angiography, which is still an invasive process. Recent advances of MR angiography have started to bring us into a new area of diagnosis for stroke patients. While using MRA at the out-patient clinic for screening patients with cerebrovascular disease, we have had a chance to diagnose DAVFs. We discussed MRA findings concerning DAVFs, comparing them with the findings of conventional angiography. We also stressed the need to set the slab so as to include the entire posterior fossa in order to disclose any vascular anomaly around the lateral and sigmoid sinus.
