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.
