3D black blood T1-weighted sequence (T1 SPACE) at 3 T was performed for the patients.
T1 SPACE was helpful in the diagnosis of subacute cerebral venous thrombosis.
T1 SPACE offered excellent visualization of the thrombus as evident high signal intensity.
The sensibility/specificity for T1 SPACE were 100%/100% per patient and 96.7%/100% per segment.
