摘要:

介入治疗在神经、血管和乳腺等手术中广泛使用。在影像学检查引导下,机器人辅助的介入治疗可以有效提高介入治疗的精准性和安全性,已成为当前介入手术的重要发展方向。与其他介入成像方法相比,磁共振介入成像(interventional magnetic resonance imaging, i-MRI)具有高软组织对比度、多对比度、可定量成像、无电离辐射等优点,在介入治疗的引导中具有巨大优势。然而,磁共振成像(magnetic resonance imaging,MRI)的成像速度相对较慢,对介入器械的兼容性要求高,是当前i-MRI引导治疗中面临的主要挑战。得益于快速i-MRI以及磁兼容介入设备等技术的发展,i-MRI在神经介入、心血管介入、前列腺介入以及乳腺介入等临床手术中发挥了重要的作用。本文总结i-MRI技术的发展现状及i-MRI的临床应用现状,分析i-MRI目前所面临的成像速度慢和时空分辨率难以平衡等挑战,并对i-MRI在多模态成像、实时MRI以及i-MRI引导下的介入机器人手术等方面的发展机遇进行展望。

Abstract:

Interventional therapy has been widely used in surgeries involving neurology, vasculature, and breasts.Image-guided, robot-assisted interventional therapy significantly enhances surgical precision and safety, emerging as a critical trend in modern interventional surgery. Among various interventional imaging methods, interventional magnetic resonance imaging (i-MRI) stands out due to its excellent soft tissue differentiation, diverse imaging contrasts, ability to yield quantitative data, and no ionizing radiation. However, the challenges facing MRI-guided therapy include the relatively low speed of imaging and the stringent compatibility demands of interventional devices. Advance in the rapid i-MRI techniques and MR-compatible equipment have propelled i-MRI to a pivotal role in clinical applications, encompassing neurological, cardiovascular, prostate, and breast interventions. This review initially provides an overview of the current i-MRI landscape. It then consolidates the application of i-MRI in multiple medical interventions, offering illustrative examples. The article further delves into the obstacles posed by i-MRI, specifically slow imaging speed and the delicate spatiotemporal resolution balance. Ultimately, it envisages the growth potential of i-MRI in multimodal imaging, real-time MRI, and i-MRI-guided interventional robotic surgery.
