SWI与3D-PCASL联合应用对急性脑梗死出血转化的预测研究
Combined with SWI and 3D-PCASL in prediction of bleeding after acute cerebral infarction
摘要
Abstract
Objective:To evaluate the clinical value of combined using 3.0T magnetic resonance magnetic susceptibility weighted imaging(SWI) and three dimensional pseudo continuous arterial spin labeling(3D-PCASL) in prediction of hemorrhagic transformation(HT) after acute cerebral infarction.Methods:Fifty-four cases of acute cerebral infarction(＜72 h) were performed conventional MRI,3D-PCASL and SWI.The SWI were used to assess the type of HT.Combined with SWI and 3D-PCASL,the infarction area,HT area and cerebral blood flow (CBF) of each patient were calculated and the correlation relationship among them were analyzed.Results:In 54 cases of acute cerebral infarction,19 cases were HT,13/19 cases were HI type,6/19 cases were PH type.The average rCBF zone in HI or PH lesions and area around two types of the lesions were (32.787±10.876),(26.655±19.325),(26.033±10.930),(28.984±11.019)mL/(100g·min),the differences of rCBF in HI and PH lesions area difference was statistically significant (t=0.766,P=0.000,＜0.01,t=0.834,P=0.041,＜0.05).Within and around the 54 cases of acute cerebral infarction lesions,the high perfusion hemorrhage presented in 42.8％ and 50％ lesions,respectively.Normal perfusion and surrounding hemorrhage presented in 50％ and 37.5％ of lesions,respectively.Hypo-perfusion and the surrounding hemorrhage presented in 31.7％ and 28.1％ lesions,respectively.Acute cerebral infarction and HT lesion area and the surrounding low,normal,high perfusion of the t test analysis statistically significant (t=0.658,P=0.002,＜0.01).Conclusion:Combined the SWI and 3D-PCASL is useful in prediction of HT after acute cerebral infarction.关键词
