Abstract:
PURPOSE:To compare the diagnostic performance of magnetic resonance (MR) sequences for the evaluation of cerebral venous sinus thrombosis (CVST) during follow-up examinations.
MATERIALS AND METHODS:Thirteen cases that were confirmed to be CVST between January 2006 and March 2016 were included in this study. Two neuroradiologists independently examined each initial and follow-up MR sequence image in random order.
RESULTS:Gadolinium-enhanced T1-weighted imaging (Gd-enhanced T1WI) was the most sensitive sequence for the detection of CVST in the initial and follow-up MR examinations (82% and 55.3%, respectively). Among the non-enhanced MR sequences of the initial examination, gradient-recalled echo was the most sensitive (77.4%), fluid-attenuated inversion recovery (FLAIR) had low sensitivity (34.4%). The overall diagnostic performances of all MR sequences except for FLAIR decreased during the follow-up. FLAIR was the most sensitive during follow-up, and was also the only sequence with increased sensitivity during follow-up (from 34.4% to 55.6%).
CONCLUSION:Gd-enhanced T1WI had the best diagnostic performance for CVST in both initial and follow-up MR examinations. Therefore, it is reasonable to use Gd-enhanced T1WI to evaluate CVST during follow-up examinations. However, for patients who cannot tolerate MR contrast agents, the use of FLAIR to assess the remaining CVST during the follow-up may be helpful.
