大腦中動(dòng)脈高密度征與磁敏感血栓征對(duì)大腦中動(dòng)脈閉塞比較研究
[Abstract]:Objective to compare the high density sign of middle cerebral artery (HMCAS) and magnetic sensitive thromboembolism (SVS) in showing occlusive thrombosis of middle cerebral artery (MCA). Methods the imaging data of CT and MRI (including SWI and MRA sequences) in 41 patients with MCA proximal occlusion were retrospectively analyzed. The sensitivity, specificity, positive predictive value, negative predictive value and their correlation of HMCAS,SVS in showing responsible vascular thrombosis were analyzed. Results among 41 patients with acute cerebral infarction in MCA region, 27 patients with proximal ipsilateral MCA were found to be occluded by MRA, and 22 patients with SVS,CT by SWI showed sensitivity (7878%) and specificity (93,100%) of HMCAS.HMCAS,SVS in showing responsible vascular thrombosis. Positive predictive value (95%) and negative predictive value (68%). In all patients, HMCAS and SVS were highly consistent in predicting proximal occlusion of MCA (魏 = 0.853). In patients with proximal MCA occlusion confirmed by MRA, HMCAS and SVS had good consistency in predicting proximal MCA occlusion (魏 = 0.786). Conclusion HMCAS,SVS has good sensitivity and high specificity in showing proximal thrombus of MCA, and there is good consistency between them.
