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.
