Abstract
Objective To discuss the diagnostic values of CT and MRI for hemorrhagic transformation(HT) after cerebral infarction .Methods 45 patients with HT from two hospitals from January 2011 to April 2014 were chosen as research objects . Their clinical data were retrospectively analyzed and outcomes of CT and MRI were compared .Results Among 45 patients , there were 34 cases (75 .6% ) with intracerebral hematoma ,11 cases (24 .4% ) with sheet ,spot and strip hemorrhage in focus of cerebral infarction .Among them ,there were 24 cases (53 .3% ) with secondary hemorrhage after large cerebral infarction , 15 cases (33 .3% ) with hemorrhage secondary to medium area of infarction ,and 6 cases (13 .3% ) with hemorrhage secondary to little area of infarction .10 cases (22 .2% ) with HT were detected by CT and 45 cases (100% ) were detected by MRI (P<0 .05);9 cases (20 .0% ) of supratentorial hemorrhage and 1 case (2 .2% ) of subtentorial hemorrhage were detected by CT while 39 cases (86 .7% ) of supratentorial hemorrhage and 6 case (13 .3% ) of subtentorial hemorrhage were detected by MRI (all P<0 .05) .Conclusion MRI has more accuracy and sensitivity than CT in diagnosis of HT ,which has great significance in judgment of bleeding time ,guidance of clinical treatment and judgment of prognosis of disease .关键词
