magnetic resonance angiography in the diagnosis of cerebral arteriovenous malformation and dural arteriovenous fistulas: comparison of time-resolved magnetic resonance angiography and three dimensional time-of-flight magnetic resonance angiography
background traditional digital subtraction angiography (dsa) is currently the gold standard diagnostic method for the diagnosis and evaluation of cerebral arteriovenous malformation (avm) and dural arteriovenous fistulas (davf). objectives the aim of this study was to analyze different less invasive magnetic resonance angiography (mra) images, time-resolved mra (tr-mra) and three-dimensional ti...

متن کاملMagnetic resonance angiography of cerebral arteriovenous malformations.
Magnetic resonance (MR) angiography as a method for the long-term follow-up of cerebral arteriovenous malformations (AVMs) was assessed in 14 patients with cerebral AVMs. These patients were either untreated or treated with transarterial embolization and/or stereotactic radiosurgery (gamma knife). Two-dimensional- and three-dimensional (3D)-time-of-flight (TOF) techniques were useful for follow...
متن کاملEvaluation of cerebral vasoreactivity by three-dimensional time-of-flight magnetic resonance angiography.
BACKGROUND AND PURPOSE Cerebral vasoreactivity is an important indicator of the reserve capacity of the cerebral circulation. To make a quantitative analysis of cerebral vasoreactivity in individual major arterial territories, we evaluated the response to acetazolamide using three-dimensional time-of-flight magnetic resonance angiography. METHODS We examined 10 healthy volunteers and 6 patien...
متن کاملHemodynamic quantification in brain arteriovenous malformations with time-resolved spin-labeled magnetic resonance angiography.
BACKGROUND AND PURPOSE Unenhanced time-resolved spin-labeled magnetic resonance angiography enables hemodynamic quantification in arteriovenous malformations (AVMs). Our purpose was to identify quantitative parameters that discriminate among different AVM components and to relate hemodynamic patterns with rupture risk. METHODS Sixteen patients presenting with AVMs (7 women, 9 men; mean age 37...
