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 کاملThree-dimensional contrast-enhanced magnetic resonance pulmonary angiography in the study of pulmonary vascular pathology.
OBJECTIVES To assess the feasibility of performing pulmonary angiography using MRI with contrast enhancement in patients with pulmonary vascular disease. METHODS We present our experience in ten individuals, two controls and eight patients who underwent the exam after injection of a gadolinium-based contrast agent on a 1 Tesla MR scanner using a time-of-flight sequence and breath-holding duri...
متن کاملTime-resolved Magnetic Resonance Angiography for assessment of recanalization after coil embolization of visceral artery aneurysms
BACKGROUND Follow-up imaging after coil embolization of visceral artery aneurysms is important for detecting recanalization. However, CT examination is susceptible to coil artifacts, which sometimes makes it difficult to assess recanalization. We report 2 cases where recanalization was successfully visualized using time-resolved magnetic resonance angiography after coil embolization of visceral...
متن کاملFree breathing contrast-enhanced time-resolved magnetic resonance angiography in pediatric and adult congenital heart disease
BACKGROUND Contrast enhanced magnetic resonance angiography (MRA) is generally performed during a long breath-hold (BH), limiting its utility in infants and small children. This study proposes a free-breathing (FB) time resolved MRA (TRA) technique for use in pediatric and adult congenital heart disease (CHD). METHODS A TRA sequence was developed by combining spiral trajectories with sensitiv...
متن کاملThree-Dimensional Time-of-Flight Magnetic Resonance Angiography Detection of Duplication of the Vertebral Artery in a Large Chinese Population
BACKGROUND The aim of this study was to investigate duplication of the vertebral artery (VA) using three-dimensional time-of-flight (3D TOF) magnetic resonance angiography (MRA) in a large study population to further our understanding of vascular variations. MATERIAL AND METHODS A retrospective analysis of 3D TOF-MRA data in 12 826 cases was performed. The occurrence rate of VA duplication was ...
