Five patients with arteriovenous malformations (AVMs) were evaluated using a novel dynamic MRA (dMRA) technique termed TrueFISP based Spin Tagging with Alternating Radiofrequency (TrueSTAR). The results are compatible with time-of-flight (TOF) MRA results. Dynamic MRA demonstrated the blood flow pattern through feeding arteries, nidus and draining veins with high temporal resolution (<100ms), and may provide complementary information in the clinical evaluation of AVMs.
