The value of MR three-dimensional cranial volume imaging in evaluating collateral circulation in pediatric patients with cerebral venous sinus thrombosis
Objective:To explore the value of three-dimensional brain volume imaging(3D-BRAVO)in assessing collateral circulation in children with cerebral venous sinus thrombosis(CVST).Methods:Eighty children with cerebral venous sinus thrombosis admitted to our hospital from January 2020 to December 2023 were selected,all of whom were diagnosed with CVST.All patients underwent skip magnetic resonance venous imaging(TOF-MRV),phase contrast venous angiography(PC-MRV),and 3D-BRAVO sequence enhancement scanning.The diagnostic efficacy of several detection methods was compared through ROC curves.Results:Through comprehensive evaluation using various imaging examination methods,it was found that there were 29 cases of single infection,21 cases in two locations,17 cases in three locations,8 cases in four locations,3 cases in five locations,and 2 cases in six locations in 80 pediatric patients.152 segments of venous sinus with thrombosis,including 30 superior sagittal sinus,15 straight sinus,30 right transverse sinus,32 left transverse sinus,31 right sigmoid sinus,and 14 left sigmoid sinus;Among 80 children with CVST,the detection rate of TOF lesions was 76.25%,and the detection rate of PC-MRV lesions was 78.75%;The detection rate of lesions in 3D-BRAVO enhanced imaging is 100%;All three diagnostic methods have certain diagnostic efficacy for CVST,among which TOF has a sensitivity of 89%and specificity of 59%,PC-MRV has a sensitivity of 85%and specificity of 70%,3D-BRAVO has a sensitivity of 94%and specificity of 71%,and its AUC is 0.893,which is higher than TOF(0.712)and PC-MRV(0.846).Conclusion:The detection rate of lesions in pediatric CVST using 3D-BRAVO enhanced scanning sequence is 100%.Compared to TOF sequence and PC-MRV sequence,it has a higher detection rate and better diagnostic efficacy.It can better display the true morphology and anatomical structure of venous sinus thrombosis and provide reference for clinical diagnosis.
