Implication

Prospective study demonstrates enhanced detection of deep cerebral venous thrombosis with MRV, highlighting its diagnostic superiority over conventional MRI sequences.

Key Points

To evaluate the diagnostic efficacy of magnetic resonance venography compared to conventional magnetic resonance imaging sequences in detecting cerebral venous thrombosis.
Prospective single-center study including 55 patients clinically suspected of having cerebral venous thrombosis between September 2022 and June 2024.
Patients underwent conventional MRI sequences (T1 SE, T1 FLAIR, T2 FSE, T2*), diffusion-weighted imaging (DWI), and 2D time-of-flight MRV.
Differences in detection rates between MRV and conventional T1w/FLAIR sequences were evaluated using chi-square tests (significance threshold p < 0.05).
Detection rates were identical or statistically similar between MRV and T1w/FLAIR for the superior sagittal sinus (61.8%), right transverse sinus (47.3%), and sigmoid sinuses.
Thrombosis in deep venous segments was detected significantly more frequently by MRV than by T1w/FLAIR (21.8% vs. 3.6%, p=0.0104).
Overall cerebral venous thrombosis identification trended higher with MRV compared to T1w/FLAIR (16.3% vs. 5.4%, p=0.0565).
