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.
