Abstract
- We report a hemodynamical assessment of the blood turnover pattern as well as the imaging of cavernous hemangioma in a cavernous sinus using time-resolved contrast enhanced 2D projection MRA, also known as MR-DSA, and conventional digital subtraction angiography (DSA), before and after radiotherapy. MR-DSA showed very fast dynamical images of a contrast turnover pattern and was well matched with the findings obtained from DSA. MR-DSA is a non-invasive study, and can replace DSA in examining a vascular tumor for the initial work-up and follow-up examination.
