Abstract

Objective: We evaluated the diagnostic value of gradient-echo (GRE) imaging in patients with "cerebral venous and sinus thrombosis" (CVST).

Materials and methods: In total, 130 thrombosed venous segment signal intensities in 45 patients with CVST were analyzed retrospectively using magnetic resonance imaging and magnetic resonance venography.

Results: The 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).

Conclusions: The T2* GRE sequence had a high diagnostic value for detecting both acute and subacute SSS, DV, and CV thromboses.

Keywords: Cerebral venous sinus thrombosis; Gradient-echo (GRE); Magnetic resonance imaging; Magnetic resonance venography (MRV).
