MRI is used for guiding and monitoring interventional surgery with MR-compatible instruments and devices, which is called MRI-guided interventions. The screen simultaneously displays the probe and the patient’s images, which helps to guide and monitor the surgery, so surgeons can adjust treatment plan to ensure the effectiveness and safety of the interventional surgery. This article reviews the principle and the current development of the MRI-guided interventions, then introduces main components of MRI-guided intervention system, clinical application and the development trend of the system.
