A developmental venous anomaly (DVA) is a common vascular malformation, with an unusual-locating collection vein and fine venous structures draining into it. Occasionally, abnormal signal intensity is combined in draining area of DVA, which is a result of venous congestion. In this work, we explored the magnetic susceptibility of draining veins in DVAs with and without venous congestion. DVAs with venous congestion showed higher susceptibility values in collecting veins than those without venous congestion. Using 3D GRE and QSM, we could assess the oxygen metabolism of brain tissue with venous congestion.
