Intracranial DAVFs are most commonly found in the cavernous, transverse, and sigmoid sinuses. MR imaging and MR angiography can be used to screen for these lesions and determine if there is cortical venous drainage. Conventional angiography still has a major role in screening and is mandatory prior to any therapy. Spinal DAVFs are uncommon lesions seen predominantly in older men. The diagnosis can be suspected with MR imaging if a large draining vein is seen in association with swelling and enhancement of the conus and increased signal on T2-weighted images. MR angiography shows some promise in identifying the vascular anatomy of these lesions.
颅内硬脑膜动静脉瘘最常见于海绵窦、横窦和乙状窦。磁共振成像（MR）和磁共振血管造影（MRA）可用于筛查这些病变，并确定是否存在皮质静脉引流。传统血管造影在筛查中仍起主要作用，并且在任何治疗前都是必需的。脊髓硬脑膜动静脉瘘是少见病变，主要见于老年男性。如果在圆锥肿胀、强化以及T2加权像信号增高的同时看到粗大引流静脉，磁共振成像可怀疑该诊断。磁共振血管造影在识别这些病变的血管解剖方面显示出一定前景。
