[Abstract] Objective: To study the value of phase-contrast sequence MRV in evaluating relationship between meningioma and cranial venous sinus.Materials and Methods: Analyzing 26 Phase-contrast Sequence MRV images of meningioma beside venous sinus. Observing the location concern with venous sinus and the meningioma, and the degree that the tumor compressing, eroding and obstructing the venous sinus. Then, comparating and analyzing the diagnoses of MRV with the findings of operation one by one.Results: All of the 26 phase-contrast sequence MRV images are cleraly displayed: (1) 11 cases suggest that the venous sinus was compressed of different degree, and it was confirmed by operation, in which it was found that the venous sinus had adhesion with the tumor, and the coincidence rate is 100%. (2) 6 cases suggest that the tumor clung to the venous sinus, four of which were confirmed by operation that the venous sinus was not eroded, while the other two were comfirmed to be eroded. (3) 9 cases suggest that there was no relationship between the tumor and venous sinus, and it was confirmed by operation. The coincidence rate is 100%.Conclusions: As an economical, non-invasive, non-contrast media imaging technology, phase-contrast sequence MRV has values to evaluating the relationship between meningioma and cranial venous sinus. It has important guiding significance when selecting surgical approach of meningioma close to venous sinus, and preventing complication after operation. It is worth routine using before operation.
