摘　　要：目的:研究在颅脑外伤诊断中应用CT与磁共振成像检查的临床价值。方法:从2021年1月~2022年11月选择50例颅脑外伤病例,均实施CT检查,并予以磁共振成像检查,对比分析两种检查方式弥漫性轴索损伤阳性率,并对两种检查方式的病灶检出情况进行对比。结果:磁共振成像检查中,弥漫性轴索损伤阳性率为82.00%,29例弥漫性脑肿胀阳性,14例蛛网膜下腔出血阳性,脑室出血阳性23例,硬膜外血肿阳性11例,出血性病灶阳性10例,非出血性病灶阳性32例;在CT检查中,弥漫性轴索损伤阳性率为54.00%,11例弥漫性脑肿胀阳性,26例蛛网膜下腔出血阳性,脑室出血阳性42例,硬膜外血肿阳性20例,出血性病灶阳性25例,非出血性病灶阳性16例;磁共振成像检查对弥漫性脑肿胀、蛛网膜下腔出血、脑室出血、非出血性病灶、非出血性病灶阳性检出率高于CT检查,对比差异有统计学意义(P<0.05)。磁共振成像检查显示25例轴外损伤、13例脑深部挫伤、45例脑内损伤,其中31例额叶损伤、14例颞叶损伤,在CT检查中,21例轴外损伤、4例脑深部挫伤、38例脑内损伤,其中25例额叶损伤、13例颞叶损伤,磁共振成像检查对轴外损伤、脑深部挫伤的检出例数高于CT检查,对比差异有统计学意义(P<0.05)。结论:在颅脑外伤诊断中,CT与磁共振成像检查均可以起到诊断作用,但相比于CT检查,磁共振成像检查对病灶检出率更高,适合在较为严重患者中应用,使诊断准确性提高,临床检查可以结合患者实际情况选择适合的检查方式。Objective:To investigate the clinical value of CT and magnetic resonance imaging in the diagnosis of craniocerebral trauma.Methods:50 cases of craniocerebral trauma were selected from January 2021 to November 2022,and CT examination and magnetic resonance imaging were performed.The positive rate of diffuse axonal injury was compared and analyzed by the two examination methods,and the detection of lesions were compared by the two examination methods.Results:In MRI examination,the positive rate of diffuse axonal injury was 82.00%,29 cases were positive for diffuse brain swelling,14 cases were positive for subarachnoid hemorrhage,23 cases were positive for ventricular hemorrhage,11 cases were positive for epidural hematoma,10 cases were positive for hemorrhagic lesion and 32 cases were positive for non-hemorrhagic lesion.In CT examination,the positive rate of diffuse axonal injury was 54.00%,11 cases were positive for diffuse brain swelling,26 cases were positive for subarachnoid hemorrhage,42 cases were positive for ventricle hemorrhage,20 cases were positive for epidural hematoma,25 cases were positive for hemorrhagic lesion and 16 cases were positive for non-hemorrhagic lesion.The positive detection rates of diffuse brain swelling,subarachnoid hemorrhage,ventricle hemorrhage,non-hemorrhagic lesions and non-hemorrhagic lesions by MRI were higher than those by CT,and the difference was statistically significant(P<0.05).Magnetic resonance imaging showed 25 cases of extra-axial injury,13 cases of deep brain contusion and 45 cases of intracerebral injury,including 31 cases of frontal lobe injury and 14 cases of temporal lobe injury.CT examination showed 21 cases of extra-axial injury,4 cases of deep brain contusion and 38 cases of intracerebral injury,among which 25 cases of frontal lobe injury and 13 cases of temporal lobe injury.The number of cases of extra-axial injury and deep brain contusion detected by MRI was higher than that by CT,and the difference was statistically significant(P<0.05).Conclusion:Both CT and
