目的探讨CT和MRI在弥漫性轴索损伤检出情况中的临床价值。方法选取鹤壁市人民医院2014年7月—2015年11月收治的弥漫性轴索损伤患者65例,入院后均接受CT和MRI检查,根据影像学检查结果对比两组患者的阳性检出率和病灶检出情况。结果 65例患者MRI检查阳性检出率为93.9%(61/65),高于CT检查的53.9%(35/65),差异有统计学意义(P<0.05),且MRI检查对于位于丘脑、基底核、胼胝体、皮质下脑白质、脑干及小脑部位的病灶检出例数均高于CT检查,且病灶检出例数也高于CT检查,差异有统计学意义(P<0.05)。结论MRI与CT检查均可为弥漫性轴索损伤的诊断提供影像学依据,但MRI检查对此类病灶具有更高的诊断敏感性,其检查结果更为可靠。
Objective To investigate the clinical value of CT and MRI in detection of diffuse axonal injury. Methods Sixty-five patients with diffuse axonal injury who were treated in Hebi Municipal People’s Hospital from July 2014 to November 2015 were selected. CT and MRI were performed after admission. According to the results of imaging examination, the positive detection rate and Lesions detected. Results The positive rate of MRI examination in 65 patients was 93.9% (61/65), which was higher than that of CT examination (53.9%, 35/65), the difference was statistically significant (P <0.05) The number of lesions detected in basal ganglia, corpus callosum, subcortical white matter, brainstem and cerebellum was higher than that of CT, and the number of lesions detected was also higher than that of CT. The difference was statistically significant (P <0.05). Conclusion Both MRI and CT scan can provide imaging evidence for the diagnosis of diffuse axonal injury. However, MRI examination has higher diagnostic sensitivity for such lesions and the test results are more reliable.
