超短回波时间磁共振血管成像
Ultra-short echo time magnetic resonance angiographyA non-contrast-enhanced imaging technique that uses ultra-short echo times to visualize blood vessels by exploiting the high signal intensity of flowing blood and the low signal intensity of surrounding tissues. / 一种非对比增强成像技术，利用超短回波时间通过利用流动血液的高信号强度和周围组织的低信号强度来可视化血管。
