实例介绍
【实例简介】
Phase-Contrast Magnetic Resonance (PCMR) is a technique used to quantitatively measure blood velocity and determine blood flow. In the first section, the technical aspects of the technique are described including the basic physics covering the generation of the phase-based velocity measurements, the specific implementation of the technique in pulse sequences, and MR parameters specific to PCMR. Advanced acquisition methods such as real-time imaging, tissue phase mapping, and 4D PCMR are described, as well as effects of parameter choices on temporal and spatial resolution. The analysis of the PCMR velocity images is explained, specifically highlighting physiologically relevant velocity and flow metrics that can be calculated from the PCMR measurements. In the second section, the clinical applications of PCMR are surveyed, concentrating on the information PCMR can provide as a complementary hemodynamic assessment of systolic and diastolic function to aide both diagnosis and prognosis in patients with cardiovascular disease. Disease conditions highlighted include myocardial disease, valve disease, and vascular disease. Special emphasis is given to congenital heart disease, where a significant number of PCMR applications have been developed.

小贴士
感谢您为本站写下的评论，您的评论对其它用户来说具有重要的参考价值，所以请认真填写。
- 类似“顶”、“沙发”之类没有营养的文字，对勤劳贡献的楼主来说是令人沮丧的反馈信息。
- 相信您也不想看到一排文字/表情墙，所以请不要反馈意义不大的重复字符，也请尽量不要纯表情的回复。
- 提问之前请再仔细看一遍楼主的说明，或许是您遗漏了。
- 请勿到处挖坑绊人、招贴广告。既占空间让人厌烦，又没人会搭理，于人于己都无利。
