Abstract：Objective To explore the diagnostic value of ColorViz multi phase CT angiography(ColorViz mCTA)in large and middle artery occlusion cerebral infarction.Methods A total of 306 patients with acute ischemic stroke in our hospital were selected.All patients were completed multi-phase CTA and MRI-DWI examination.Multi stage CTA vascular information was summarized by FastStroke software.Then,we compared the differential detection of ColorViz mCTA for large and small in-farcts,analyzed the correlation between ColorViz mCTA and distinguishing large and small infarcts,and evaluated the diagnos-tic value of ColorViz mCTA for distinguishing the large and small acute cerebral infarction using receiver operating characteristic curve(ROC).Results A total of 323 lesions were detected,there were 190 cases of large and middle artery occlusive infarc-tion and 133 cases of small artery occlusive cerebral infarction.The larger the lesion,the higher the detection rate of ColorViz mCTA(P<0.001),and there was a significant correlation between ColorViz mCTA and lesion size(r=0.749,P<0.001);Color-Viz mCTA could distinguish the large and small lesions with an area under the curve(AUC)of 0.933(P<0.001).When the le-sion area was equal to 2.53 cm2,ColorViz mCTA had the maximum diagnostic efficacy,with a sensitivity of 91.1%and a specific-ity of 86.1%.Conclusion ColorViz mCTA can be used for the targeted diagnosis of large and medium cerebral infarcts caused by cerebral artery occlusion.
