The Value of Multimodal MRI in the Diagnosis of Cerebral Microhemorrhage Caused by Mild Traumatic Brain Injury
Objective To explore the diagnostic value of multimodal MRI in mild traumatic brain injury microhemorrhage(MTBI-CMB),in order to improve the diagnostic level of this disease.Methods The clinical data and imaging data of 200 patients with mild traumatic brain injury(MTBI)who were clinically diagnosed from September 2017 to December 2023 were retrospectively analyzed,and the efficacy and consistency of multimodal MRI diagnostic mode and conventional imaging mode in the detection of MTBI-CMB were evaluated by statistical methods.Results A total of 400 MTBI-CMB lesions were detected in 70 cases of 200 MTBI patients,of which 25 were detected in 16 cases with a sensitivity of 6.25%and a specificity of 73.08%.Routine MRI was used to detect 95 cases in 43 cases,with sensitivity 23.75%and specificity 57.69%.DWI detected 106 samples from 42 patients with sensitivity 26.50%and specificity 46.92%.SWI was detected in 69 cases with 330 samples,sensitivity 82.50%,specificity 63.08%.The consistency test of Kappa test showed that SWI had a good consistency with multimodal MRI diagnosis(Kappa value=0.431,P<0.05).Conclusion The early clinical manifestations of MTBI-CMB have certain characteristics,and multi-modal MRI has higher diagnostic efficacy in the early diagnosis of MTBI-CMB than SWI,which can provide scientific basis for the early clinical intervention treatment of MTBI-CMB.
