While time of flight (TOF) angiography detects occlusion of arteries in patients with acute ischemic stroke due to the absence of blood flow in the occluded vessel, Susceptibility Weighted Imaging (SWI) enables visualization of the occluding thrombus. In our study we investigated the sensitivity of both methods for the detection of peripheral and central vessel occlusion and found SWI to be superior to TOF-angiography for the detection of peripheral thrombi.
