尽管X射线透视(XRF)几十年来一直指导经导管的诊断和治疗，但仍然存在一定的局限性。XRF对组织的可视化仍然很差，并且依赖于不传达深度信息的阴影的投影。辅助超声心动图克服了其中的一些局限性，但仍然存在不理想或不可靠的成像窗口。此外，儿童暴露在电离辐射中会增加患癌症的风险。使用实时磁共振成像(MRI)的介入平台可以在没有辐射的情况下提供卓越的图像指导。尽管仍然存在许多挑战，但实时磁共振成像具有彻底改变经导管治疗的潜力。
Although x-ray fluoroscopy (XRF) has guided diagnostic and therapeutic transcatheter procedures for decades, certain limitations still exist. XRF still visualizes tissue poorly and relies on projection of shadows that do not convey depth information. Adjunctive echocardiography overcomes some of these limitations but still suffers suboptimal or unreliable imaging windows. Furthermore, ionizing radiation exposure in children imparts a cancer risk. An interventional platform using real-time magnetic resonance imaging (MRI) may offer superior image guidance without radiation. Although there are many remaining challenges, but real-time MRI has the potential to revolutionize transcatheter therapeutics.
