Comparative study on values of CT and MRI for diagnosis of diffuse axonal injury / 医疗卫生装备

ABSTRACT

Objective To explore the application values of CT and MRI in the diagnosis of diffuse axonal injury.Methods Totally 52 cases of diffuse axonal injury patients from November 2012 to December 2014 were retrospectively analyzed,who underwent examinations by CT and MRI,then the abilities to find the lesions and the sensitivities of CT and MRI were compared.Results The diagnosis sensitivity of CT (48.08％) was significantly lower than that of MRI (73.08％) (P＜0.05).There were 56 lesions of 25 abnormal cases detected by CT,and there were 99 lesions in the T1WI sequence,137 lesions in T2WI sequence,171 lesions in the FLAIR sequence of 38 abnormal cases detected by MRI.The numbers of lesions found by MRI were significantly higher than those by CT (P＜0.05).The radiographic signs showed as diffuse brain swelling,subarachnoid and ventricular hemorrhage,epidural hematoma and parenchymal hemorrhage or edema.Conclusion CT and MRI contribute to the diagnosis and treatment of diffuse axonal injury.MRI gains advantages over CT in the sensitivity of diagnosing diffuse axonal injury,and thus is worthy promoting clinically.
