Diagnostic value of T2*-weighted gradient-echo MRI for segmental evaluation in cerebral venous sinus thrombosis

ObjectiveWe evaluated the diagnostic value of gradient-echo (GRE) imaging in patients with “cerebral venous and sinus thrombosis” (CVST).Materials and MethodsIn total, 130 thrombosed venous segment signal intensities in 45 patients with CVST were analyzed retrospectively using magnetic resonance imaging and magnetic resonance venography.ResultsThe T2* GRE sequence had a diagnostic value for detecting acute and subacute superior sagittal sinus (SSS) thrombosis and thrombosis of the deep veins (DVs), and cortical veins (CVs; P< .05).ConclusionsThe T2* GRE sequence had a high diagnostic value for detecting both acute and subacute SSS, DV, and CV thromboses.
