Our objectives were to study by PC-MRI intracranial flow alterations in patients with cerebral venous thrombosis (CVT). Thanks to a specific selection of MRI parameters, and of key-parameter velocity encoding values, intracerebral and cervical arterial and venous flows, as well as cervical and ventricular CSF flows were evaluated in 6 patients with diagnosed CVT on MR Venography. PCMRI did not detect any venous flow in the veins and/or sinuses with thrombosis detected on Venography, and it showed alterations of CSF flows in 5/6 patients. PC-MRI is a complementary tool in the evaluation of venous thrombosis effects on intracranial dynamics.
