Ventricular Microaneurysms in Moyamoya Angiopathy Visualized with 7T MR Angiography.
The pathophysiologic role of hemodynamic alteration to peripheral vessels in Moyamoya angiopathy and the formation of microaneurysms remains unclear. The purpose of this study was to investigate microaneurysms in collateral Moyamoya vessels by using 7T ultra-high-field MR imaging. Ten patients with Moyamoya disease were evaluated with TOF-MRA at 7T acquired with 0.22 × 0.22 × 0.41 mm(3) resolut...
متن کاملMoyamoya disease: comparison of assessment with MR angiography and MR imaging versus conventional angiography.
PURPOSE To evaluate magnetic resonance (MR) angiography and MR imaging in assessment of moyamoya disease. MATERIALS AND METHODS The cases of 26 patients with moyamoya disease were evaluated prospectively. After three-dimensional time-of-flight 1.5-T MR angiography and MR imaging, images were evaluated in blinded separate interpretation. RESULTS MR angiography and MR imaging accurately depic...
متن کاملHypertension correlates with lenticulostriate arteries visualized by 7T magnetic resonance angiography.
Hypertension, a major risk factor for stroke, is associated with altered arterial anatomy and function; however, the limited resolution of current imaging techniques has restricted the in vivo study of microvascular changes in the brain. In this report, we quantitatively examined the lenticulostriate arteries in hypertensive patients using ultrahigh-field 7T MRI. We compared the number of stems...
متن کاملMeasuring Cerebral Blood Flow in Moyamoya Angiopathy by Quantitative Magnetic Resonance Angiography Noninvasive Optimal Vessel Analysis.
BACKGROUND Moyamoya disease causes progressive occlusion of the supraclinoidal internal carotid artery, and middle, anterior, and less frequently the posterior cerebral arteries, carrying the risk of stroke. Blood flow is often partially reconstituted by compensatory moyamoya collaterals and sometimes the posterior circulation. Cerebral revascularization can further augment blood flow. These ch...
متن کاملMR imaging of non-visualized pulmonary arteries at angiography in patients with congenital heart disease.
The aim of this study was to evaluate whether MR could depict pulmonary arterial anatomy in more detail than routine angiography in patients with congenital interruption or acquired occlusion of the left pulmonary artery or pulmonary atresia. This study included 10 patients with tetralogy of Fallot (n=6) or pulmonary atresia with ventricular septal defect (n=3) or aorticopulmonary window (n=1) ...
