ABSTRACT
Objective To explore the value of fluid-attenuated inversion recovery (FLAIR)sequence and gradient echo T2 ?weighted image (GRE-T2 ? WI)in diagnosis of acute traumatic extra-axial hemorrhage.Methods 50 patients who were diagnosed as acute traumatic extra-axial hemorrhage by plain CT underwent FLAIR and GRE-T2 ? WI in acute stage.The diagnosis consistency (Kappa ),detection rate of subarachnoid hemorrhage(SAH),epidural hemorrhage(EDH)and subdural hemorrhage(SDH)were compared.The detection rates of SAH in 8 locations among FLAIR,GRE-T2 ? WI and combination of two sequences were analyzed by Chi-square test.Results 48 patients were enrolled in the study.The diagnosis consistency of SAH between FLAIR and GRE-T2 ? WI was high (k =1.0).The detection rate of SAH was 100% for both FLAIR and GRE-T2 ? WI.Comparing with GRE-T2 ? WI and combi-nation of two sequences,FLAIR tended to misdiagnose SAH in perimesencephalic cistern (P <0.05).The diagnosis consistency of EDH between FLAIR and GRE-T2 ? WI was high (k =1.0).3 patients with EDH were all detected by FLAIR and GRE-T2 ? WI. The diagnosis consistency of SDH between FLAIR and GRE-T2 ? WI was high (k =0.943).The detection rate of 12 patients with SDH was 100% in FLAIR,and 1 patient with SDH was missed by GRE-T2 ? WI.Conclusion The detection rate of acute traumatic extra-axial hemorrhage is high for both FLAIR and GRE-T2 ? WI.Combination of two sequences can improve the accuracy of acute traumatic extra-axial hemorrhage in clinic.
