ObjectiveTo evaluate the value of MSCTV in the diagnosis of cerebral venous sinus thrombosis(CVST)，in an attempt to provide a simple but more effective imaging method in the evaluation of cerebral venous sinus thrombosis clinically.Methods32 patients with cerebral venous sinus thrombosis underwent biphasic contrastenhanced CT scan (i.e. arterial and venous phases or CTA+CTV) using a MSCT scanner (followup CT in 6 cases), with a total of 38 MSCT examination being performed.The data were independently analyzed by three experienced radiologists and CTbased diagnosis was made when there is a consensus among the three radiologists.The criteria of diagnostic accuracy, based on the results of MRI+MRV and/or DSA correlating with clinilal diagnosis, was used.ResultsFilling defect was seen within the involved venous sinuses on axial contrastenhanced CT images and moderate enhancement of the sinal wall was significantly observed.Triangular area of filling defects is the typical feature of superior sagittal sinus and sigmoid sinus thrombosis, which termed as "empty triangle sign", and thrombosis in the transverse and straight sinuses manifested as girdleshaped filling defect, which was clearly revealed on coronal and sagittal MPR.MSCTV is capable of demonstrating filling defect within sinus, competing with MRV or DSA.MSCTV possess, to a considerable degree, the ability to depict the dilated superficial cerebral veins, as well as the cerebral venous edema and/or infarction with or without hemorrhage.ConclusionMSCTV can clearly display the image characteristics of CVST.Compared to MRV or DSA, it is simple and feasible and becoming a reliable imaging method for screening patients with suspected CVST.
