ObjectiveTo explore the features of images by CT,MRI,and MRV for early cranial venous sinus thrombosis (CVST) to provide the diagnostic evidence for choosing an optimal imaging examination.
MethodsThe clinical data (imaging features of CT,MRI,and MRV) of 46 patients with CVST diagnosed between January 2009 and January 2013 were retrospectively analyzed.
ResultsBrain CT showed the direct signs of CVST in 15 cases (32.6%),and indirect signs of CVST in 8(17.4%).MRI showed the signs of CVST in 17 cases (68.0%);the diagnostic positive rate of MR venography (MRV) combined with MRI was 87.5%,84.6% of which was in line with that of digital subtraction angiography.
ConclusionCT can be used as screening tool for those highly suspect CVST cases.MRI combined with MRV show great diagnostic value for CVST.
