TR-3D-CE-MRA with an adequate diagnostic confidence index for the vascular study and temporal AVM. In comparison with CCA, the findings were the following: artifacts, none; arterial-to-venous separation, excellent; vascular visibility: ophthalmic artery, 0/2; PICA, 1/2; occipital artery, 2/2; ISS, 2/2; AUC, 9,100. Note a right temporal AVM with afferent branches from the right MCA and draining veins into the SSS and the right TS (by 2 collectors) and association with an aneurysm of the anterior communicating artery. A and B, Sagittal view with an intermediate and late arterial phase. C, Coronal view with an intermediate arterial phase. Note a faint venous SI within distal veins.
