Contrast enhanced 4D time-resolved MR angiography with CENTRA Keyhole (4D TRAK) and parallel imaging (SENSE) was performed at 3.0 Tesla in 10 patients with cerebral arteriovenous malformations (cAVM) and compared with DSA. A total acceleration of 6 (Keyhole) x 8 (SENSE) x 1.25 (half Fourier) = 60 was achieved yielding a temporal resolution of 608 msec./dynamic. In 10/10 patients, 4D TRAK allowed for reliable classification of cAVM according to Spetzler and Martin matched with DSA.
