After several years of research development cardiovascular MRI has evolved into a widely accepted clinical tool. It offers important diagnostic and prognostic information for a variety of clinical indications, which include ischaemic heart disease, cardiomyopathies, valvular dysfunction and congenital heart disorders. It is a safe non-invasive technique that employs a variety of imaging sequences optimized for temporal or spatial resolution, tissue-specific contrast, flow quantification or angiography. Cardiac MRI offers specific advantages over conventional imaging techniques for a significant number of patients. The demand for cardiac MRI studies from cardiothoracic surgeons, cardiologists and other referrers is likely to continue to rise with pressure for more widespread local service provision. Setting up a cardiac MRI service requires careful consideration regarding funding issues and how it will be integrated with existing service provision. The purchase of cardiac phased array coils, monitoring equipment and software upgrades must also be considered, as well as the training needs of those involved. The choice of appropriate imaging protocols will be guided by operator experience, clinical indication and equipment capability, and is likely to evolve as the service develops. Post-processing and offline analysis form a significant part of the time taken to report studies and an efficient method of providing quantitative reports is an important requirement. Collaboration between radiologists and cardiologists is needed to develop a successful service and multi-disciplinary meetings are key component of this. This review will explore these issues from our perspective of a new clinical cardiac MRI service operating over its first year in a teaching hospital imaging department.
经过数年的研究发展,心血管磁共振成像已发展成为一种被广泛接受的临床工具。它为多种临床适应症提供重要的诊断和预后信息,这些适应症包括缺血性心脏病、心肌病、瓣膜功能障碍和先天性心脏病。它是一种安全的非侵入性技术,采用了多种针对时间或空间分辨率、组织特异性对比、血流定量或血管造影进行优化的成像序列。对于大量患者而言,心脏磁共振成像相对于传统成像技术具有特定优势。心胸外科医生、心脏病专家和其他转诊医生对心脏磁共振成像研究的需求可能会随着更广泛的本地服务提供压力而持续上升。建立心脏磁共振成像服务需要仔细考虑资金问题以及它将如何与现有服务提供相结合。还必须考虑购买心脏相控阵线圈、监测设备和软件升级,以及相关人员的培训需求。合适成像方案的选择将由操作人员经验、临床适应症和设备能力来指导,并且可能会随着服务的发展而演变。后处理和离线分析在报告研究所需的时间中占很大一部分,提供定量报告的有效方法是一项重要要求。放射科医生和心脏病专家之间需要合作来建立一个成功的服务,多学科会议是其中的关键组成部分。本综述将从我们在一家教学医院影像科运营新的临床心脏磁共振成像服务的第一年的角度探讨这些问题。
