Letter to the Editor: Arterial spin labeling in evaluation of venous drainage pattern in brain arteriovenous malformations

Identification of venous signal on arterial spin labeling improves diagnosis of dural arteriovenous fistulas and small arteriovenous malformations.

BACKGROUND AND PURPOSE DAVFs and small AVMs are difficult to detect on conventional MR imaging/MRA or CTA examinations and often require DSA for definitive diagnosis. The purpose of this study was to assess the value of venous signal intensity on ASL imaging for making this diagnosis. MATERIALS AND METHODS Two neuroradiologists and 1 neurologist reviewed MR imaging studies in 26 patients, 15 ...

Arteriovenous shunt visualization in arteriovenous malformations with arterial spin-labeling MR imaging.

BACKGROUND AND PURPOSE A reliable quantitative technique for measuring arteriovenous (AV) shunt in vascular malformations is not currently available. Here, we evaluated the hypothesis that continuous arterial spin-labeled (CASL) perfusion MR imaging can be used to detect and measure AV shunt in patients with arteriovenous malformations (AVMs). MATERIALS AND METHODS CASL perfusion MR imaging w...

Feeding artery pressure and venous drainage pattern are primary determinants of hemorrhage from cerebral arteriovenous malformations.

PURPOSE The purpose of this study was to define the influence of feeding mean arterial pressure (FMAP) in conjunction with other morphological or clinical risk factors in determining the probability of hemorrhagic presentation in patients with cerebral arteriovenous malformations (AVMs). METHODS Clinical and angiographic data from 340 patients with cerebral AVMs from a prospective database we...
