Vascular malformations of the brain are often found in the workup of intracranial hemorrhage, seizures, focal neurological deficits, or headaches. Although CT-angiography may reveal an underlying arteriovenous malformation (AVM) or arteriovenous fistula (AVF), other vascular malformations are not easily evaluated on CT and are better seen on magnetic resonance imaging. ...

To compare a novel combined acquisition technique (CAT) of turbo-spin-echo (TSE) and echo-planar-imaging (EPI) with conventional TSE. CAT reduces the electromagnetic energy load transmitted for spin excitation. This radiofrequency (RF) burden is limited by the specific absorption rate (SAR) for patient safety. SAR limits restrict high-field MRI applications, in particular. ...
