Magnetic 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 کاملmagnetic 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 کاملValidation of cerebral arteriovenous malformation hemodynamics assessed by DSA using quantitative magnetic resonance angiography: preliminary study.
BACKGROUND The hemodynamic evaluation of cerebral arteriovenous malformations (AVMs) using DSA has not been validated against true flow measurements. OBJECTIVE To validate AVM hemodynamics assessed by DSA using quantitative magnetic resonance angiography (QMRA). MATERIALS AND METHODS Patients seen at our institution between 2007 and 2016 with a supratentorial AVM and DSA and QMRA obtained b...
متن کاملMagnetic 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 ...
متن کاملMR digital subtraction angiography of cerebral arteriovenous malformations.
BACKGROUND AND PURPOSE Although phase-contrast MR angiography provides some information regarding hemodynamics of cerebral arteriovenous malformations (AVMs), most conventional MR angiographic techniques have not been helpful in this respect. We attempted to determine the value of MR digital subtraction angiography (DSA) in assessing AVM hemodynamics. METHODS We developed an MR DSA technique ...
