摘要
目的通过优化检查流程,对3.0T CMRI的临床价值进行再评价。方法收集2010年10月-2012年4月临床怀疑有心脏疾患行3.0T CMR检查的36例患者,应用黑血对比和亮血对比成像以及心肌首过灌注和延迟增强等"一站式"优化检查,对心脏的解剖形态、运动功能和心肌的血供情况进行分析。结果 3.0T CMRI能够清楚显示各房室形态结构,36例患者中,CMRI无异常10例,缺血性心脏病7例,其中心肌缺血伴肺栓塞1例,非缺血性心肌病12例,CMRI偶然发现胸腺瘤及心包肿瘤各1例;房颤射频消融术前查体明确有无血栓3例;左室假腱索、二尖瓣返流各1例。结论 3.0T CMRI"一站式"优化检查图像质量好、可重复性强,不仅对心脏本身而且对其临近结构也可一并观察,对心脏的形态结构、心室功能以及心肌活性等生理方面可做出准确评价。
Objective To re-evaluate clinical application of 3.0T MRI by optimizing exami- nation process. Methods 36 patients with suspected cardiovascular diseases underwent contrast-enhanced CMRI on 3.0T scanner from Oct 2010 to Apr 2012. We sought to assess cardiac involvement in one-stop optimized cardiac magnetic resonance imaging （CMRI） approach including d^rk-blood, bright-blood imaging. ~]rst-p.＇~ss myocardial-perfiJsion and delayed enhancement.Cardiac morphology and function evaluation were castled out. The assessment of myocardial viability were also pertormed. Results＂ The cardiovascular images were well developed in all of these 36 cases,in which there were 10 cases with no abnormity, 7 cases with ischemic heart disease（IHD）,of which 1 case combined with pulmonary embolism（PE）, 12 cases with nonischemic myocardial disease, I case with tumonr which was occasionally found in thymus gland and pericardium respectively, and 3 cases with arrhythmias who were examined in order to find whether there were thrombus in atrium. Ft, rthermore, we also found one case with left ventricular false tendon（LVFT）and mitral regurgitation respectively. Conclusion 3.0T CMRI is a high quality and reproducible technique. It can be used to observe both heart itself and its neighborhood structt, re. and provide accurate assessment of cardiac physiology including morphology, function and myocardial viability.
