Excellent correlation was noticed among MRA, angiography, operation and ultrasound (90%). When MRA is accordant with ultrasound, it can basically substitute angiography, which is an invasive procedure. 展开 关键词: MR angiography Vascular disease of the lower extremity ...
Magnetic resonance (MR) angiography of lower extremity occlusive vascular disease has evolved into a feasible diagnostic imaging option. The previous emphasis on time-of-flight techniques was associated with lengthy acquisition times and artifactual signal losses. Those limitations pre...
•Body MR angiography •Central nervous system (CNS) MR imaging The protocol parameters can generally be adapted to work with other software platforms or releases and hardware configurations but may require small modifications that can be made by a knowledgeable and experienced MR technologist. Scan...
Introduction: The aim of this study was to evaluate the applicability of contrast enhanced magnetic resonance angiography (ce-MRA) as a first stage imaging tool for individual treatment planning in patients with lower extremity arterial occlusive disease....
When performing non-enhanced time-of-flight angiography of the lower extremity arteries at 7 T with cardiac triggering, the acquisition time is a crucial consideration. Therefore, in previous studies, saturation RF pulses were applied only every second TR. In the source images a slight artifact wi...
Three-dimensional (3D) contrast enhanced MR angiography (MRA) is another established noninvasive method to examine peripheral arteries. This method has been shown to be a promising noninvasive alternative to DSA and CTA for screening patients suspected of having lower extremity ischemia [6,7]. Howe...
