چکیده
Figure 2: MIPs of 1.5T (a) and 7T (b) PC MRA of the vasculature superior to the circle of Willis of a 39 year old, male volunteer. The acquisitions times for both sequences were about 5 minutes. Axial images were acquired with slices thickness of 0.75 mm. The 7T images depict third order branches of the circle of Willis, e.g. the paracentral artery.

Hypertension 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 کاملTime of Flight Magnetic Resonance Angiography of the Canine Brain at 3T and at 7T - A Quantitative Comparison
Introduction 7T ToF-MRA has proven to depict the major intracranial arteries in humans with a quality comparable or better than 3T or 1.5T magnets [1]. Ultrahigh field ToF-MRA has also allowed for the visualization of a larger number of the small intracranial arteries that were either not visualized or seen less clearly with lower field strength magnets [2]. The purpose of this study was to eva...
متن کاملQuantification of subcortical gray-matter vascularization using 7 Tesla time-of-flight angiography
Background The integrity of subcortical brain nuclei is associated with maintenance of regular cognitive performance levels and has been shown to be particularly affected by aging-related vascular pathology. This study aims to demonstrate applicability of high field strength magnetic resonance angiography at 7 Tesla (7T) for assessment of interindividual variation in subcortical vascularization...
متن کاملGadolinium-enhanced magnetic resonance angiography in brain death
Confirmatory tests for the diagnosis of brain death in addition to clinical findings may shorten observation time required in some countries and may add certainty to the diagnosis under specific circumstances. The practicability of Gadolinium-enhanced magnetic resonance angiography to confirm cerebral circulatory arrest was assessed after the diagnosis of brain death in 15 patients using a 1.5 ...
متن کاملA comparison between magnetic resonance angiography at 3 teslas (time-of-flight and contrast-enhanced) and flat-panel digital subtraction angiography in the assessment of embolized brain aneurysms
PURPOSE To compare the time-of-flight and contrast-enhanced- magnetic resonance angiography techniques in a 3 Tesla magnetic resonance unit with digital subtraction angiography with the latest flat-panel technology and 3D reconstruction in the evaluation of embolized cerebral aneurysms. INTRODUCTION Many embolized aneurysms are subject to a recurrence of intra-aneurismal filling. Traditionall...
