Can 3T MR angiography replace DSA for the identification of arteries feeding intracranial meningiomas?
BACKGROUND AND PURPOSE For identifying the arterial feeders of meningiomas, the usefulness of 3D TOF MRA at 3T has not been systematically investigated. This study was intended to assess whether unenhanced 3D TOF MRA at 3T can replace DSA for the identification of arteries feeding intracranial meningiomas and whether it is useful for assessing their dural attachment. MATERIALS AND METHODS Twe...
متن کاملIntracranial vascular stenosis and occlusive disease: evaluation with CT angiography, MR angiography, and digital subtraction angiography.
BACKGROUND AND PURPOSE Although digital subtraction angiography (DSA) provides excellent visualization of the intracranial vasculature, it has several limitations. Our purpose was to evaluate the ability of helical CT angiography (CTA) to help detect and quantify intracranial stenosis and occlusion compared with DSA and MR angiography (MRA). METHODS Twenty-eight patients underwent CTA, DSA, a...
متن کاملContrast-enhanced MR angiography at 3T in the evaluation of intracranial aneurysms: a comparison with time-of-flight MR angiography.
The combination of 3T and parallel-acquisition techniques holds promise for improved performance of contrast-enhanced MR angiography (MRA), in terms of speed, spatial resolution, and coverage. We present a comparison of 2 MRA techniques, including time-of-flight (TOF) and contrast-enhanced MRA, for detection and evaluation of intracranial aneurysms. Our results show that contrast-enhanced MRA w...
متن کاملFenestrations of intracranial arteries detected with 3D rotational angiography.
BACKGROUND AND PURPOSE Fenestrations of intracranial arteries are variants resulting from incomplete fusion of primitive vessels. An association with aneurysms is suggested in many studies. On conventional angiography, fenestrations are rarely visible. 3D rotational angiography (3DRA) provides improved visualization of cerebral vessels from any desired angle. We used 3DRA to assess the frequenc...
متن کاملAnatomical Evaluation of Renal Arteries and Veins in Kidney Donors by CT Angiography
Abstract Background: Renal transplantation (RT) is the transplantation of a kidney into a patient with end-stage renal disease and has become the treatment of choice for most patients with end-stage renal disease. The knowledge of renal vascular variations is of a great importance for the surgeons who approach the kidneys from the retroperitoneal o...
