弥漫性轴索损伤患者核磁SWI成像与CT成像诊断价值比较及病情严重程度的相关性

Comparison of Diagnostic Value Between SWI and CT Imaging and Correlation Between Severity of Disease in Patients with Diffuse Axonal Injury

目的探讨弥漫性轴索损伤患者核磁SWI成像与CT成像诊断价值比较及病情严重程度的相关性。方法选择2019年9月至2021年3月来我院就诊的120例弥漫性轴索损伤患者,随机分为观察组和对照组,每组60例。观察组用SWI诊断、检测患者,对照组用CT成像诊断、检测患者。对比两组患者诊断准确率、不同病灶检出率,分析SWI和CT成像与病情严重程度的相关性。结果两组DAI患者性别、年龄、BMI等一般资料比较,差异无统计学意义(P>0.05);观察组检测出未见异常出血灶的概率小于对照组,观察组检测出双侧额叶多发低密度影率、准确率明显高于对照组,差异有统计学意义(P<0.05)。观察组检测出左、右侧额叶多发低密度影率与对照组相比,无明显差异(P>0.05);观察组脑干出血的检出率明显高于对照组,差异有统计学意义(P<0.05)。观察组灰白质出血、弥漫性脑肿胀的检出率与对照组相比,无明显差异(P>0.05)。SWI和CT诊断表现与病情严重程度呈正相关(r=0.61,0.57,P<0.05)。结论SWI的准确率、检出率明显高于CT,且SWI和CT检测的诊断表现与患者病情严重程度呈显著正相关。

Objective To investigate the correlation between the diagnostic value of MRI SWI and CT imaging in patients with diffuse axonal injury and the severity of the disease.Methods 120 patients with diffuse axonal injury who came to our hospital from September 2019 to March 2021 were randomly divided into observation group and control group,with 60 cases in each group.The patients in the observation group were diagnosed and detected by SWI,and the patients in the control group were diagnosed and detected by CT imaging.The diagnostic accuracy and detection rates of different lesions were compared between the two groups,and the correlation between SWI and CT imaging and the severity of the disease was analyzed.Results There was no significant difference in gender,age and BMI between the two groups(P>0.05);The probability of detecting no abnormal bleeding focus in the observation group was lower than that in the control group.The rate and accuracy of detecting multiple low-density shadows in bilateral frontal lobes in the observation group were significantly higher than those in the control group(P<0.05).There was no significant difference in the rate of multiple low-density shadows in the left and right frontal lobes between the observation group and the control group(P>0.05);The detection rate of brainstem hemorrhage in the observation group was significantly higher than that in the control group(P<0.05).There was no significant difference in the detection rate of gray matter hemorrhage and diffuse brain swelling between the observation group and the control group(P>0.05).The diagnostic manifestations of SWI and CT were positively correlated with the severity of the disease(r=0.61,0.57,P<0.05).Conclusion The accuracy and detection rate of SWI are significantly higher than that of CT,and the diagnostic manifestations of SWI and CT were significantly positively correlated with the severity of the patient's condition.
