Multiphase CT angiography image, with each phase and follow-up CT angiography. a Peak-arterial Phase 1 image showed right M1 MCA occlusion (arrow). b, (c) Peak venous Phase 2 and late venous Phase 3 images demonstrate excellent arterial filling beyond the M1 MCA thrombus and no proximal M2 occlusion which was very short in this example (2 mm). d Follow-up CT angiography after intravenous thrombolysis administration showed complete recanalization of the arterial occlusion
