21 patients without digital subtraction angiography before surgery. †2 missing data, 308 patients were assessed via computed tomography perfusion, 5 via arterial spin labeling MR perfusion, 4 via perfusion weighted imaging, and 8 via single-photon emission computerized tomography. ‡310 patients were evaluated by digital subtraction angiography (DSA), and 17 patients were evaluated either by computed tomography angiography (CTA) or magnetic resonance angiography (MRA).
