Using MR venography,the two radiologists diagnosed dural sinus thrombosis in eight of the 17 patients with suspected dural sinus thrombosis.In these eight patients,the diagnosis was also made with CT venography.The diagnosis was confirmed by followup CT in four patients and by followup MR imaging in two patients.The MIP algorithm did not allow direct visualization of thrombus by either the CT or the MR imaging technique; however,the CT integral display algorithm enabled direct visualization of thrombus on the three-dimensional projection venograms.The systematic comparison of imaging techniques showed that CT venography reliably reveals all cerebral veins and sinuses when they are seen with MR venography.In addition,CT venography more frequently visualizes sinuses or smaller cerebral veins with low flow as compared with MR venography. Cerebral CT venography is superior to MR venography in the identification of cerebral veins and dural sinuses and is at least equivalent in the diagnosis of dural sinus thrombosis.CT venography is a viable alternative to MR venography in the examination of patients with suspected dural sinus thrombosis. |
