CMR的局限性（与超声心动图相比成本更高[但与其他模式相比不是这样]，3缺乏便携性，可用性有限，含不锈钢植入物的伪影[尽管大多数现代植入物中已不再使用]，4以及植入起搏器或心脏起搏器的患者的相对禁忌症5）已得到充分记录。应该注意的是，通过避免在肾小球滤过率降低的患者中使用钆基造影剂，已在很大程度上消除或大大降低了与钆基造影剂相关的肾源性系统性纤维化风险。6重要的是，当通过CMR评价RV时，不需要使用造影剂。因此，总的来说，CMR获得的数据的临床受益远远超过其局限性，详见以下章节。
The limitations of CMR (higher cost in comparison with echocardiography [but not in comparison with other modalities], 3 lack of portability, limited availability, artifacts from implants containing stainless steel [although no longer used in most modern implants], 4 and relative contraindication in patients with pacemaker or defibrillator5) are well documented. It should be noted that the risk of nephrogenic systemic fibrosis that has been linked to gadolinium-based contrast has largely been eliminated or greatly reduced by avoiding its use in patients with reduced glomerular filtration rate. 6 Importantly, when it comes to evaluation of the RV by CMR, use of a contrast agent is not required. Hence, on balance, the clinical benefits of the data obtained by CMR greatly outweigh its limitations as detailed in the following sections.
