交替射频信号定位(STAR)、STAR和血流无关松弛增强(STARFIRE)是血流相关和血流无关磁共振血管造影(MRA)的非对比方法。该方法依赖于由空间选择性或空间非选择性反转射频脉冲交替标记的两个图像集的采集和复杂减法。实验结果表明,射频标记期影响STAR成像显示的颈动脉血管的范围,以及STARFIRE图像中脑脊液(CSF)和脂肪的显著性。两种方法都被发现比飞行时间(TOF)血管造影的非对比MRA技术提供更详细的颈动脉描述。中华医学杂志,2009,31(1):379 - 379。(C) 2008 Wiley-Liss, Inc。
Signal Targeting with Alternating Radiofrequency (STAR) and STAR and Flow-independent Relaxation Enhancement (STARFIRE) are noncontrast methods for flow-dependent and flow-independent magnetic resonance angiography (MRA). The methods rely on the acquisition and complex subtraction of two image sets alternately labeled by spatially selective or spatially nonselective inversion radio frequency (RF) pulses. Experimental results show that the RF labeling period affects the extent of the carotid vessels seen with STAR imaging, and the conspicuity of cerebrospinal fluid (CSF) and fat in the STARFIRE images. Both methods were found to provide more detailed depiction of the carotid arteries than the alternative noncontrast MRA technique of time-of-flight (TOF) angiography. Magn Reson Med 61:117-124, 2009.
