Interventional Mri Guidance

Interventional MRI guidance is the use of magnetic resonance imaging to plan, navigate, monitor, and assess minimally invasive procedures while they are being performed. It generates detailed soft-tissue images without ionizing radiation, and rapid image updates can show anatomy, target movement, and device position, enabling clinicians to adjust trajectories or treatment delivery in response to changing conditions. In bioengineering, this approach supports the design of MRI-compatible instruments, robotic systems, imaging sequences, and therapeutic platforms. Applications include biopsy, ablation, drug delivery, and targeted interventions, where improved visualization can enhance precision, procedural control, and evaluation of treatment effects.

The closure of a patent foramen ovale (PFO) is a catheter-based intervention to prevent PFO-associated stroke. The PFO-occlusion device is advanced through the femoral vein and deployed across the interatrial septum using transesophageal echocardiography (TEE) and fluoroscopic guidance. The following protocol provides a step-by-step guide for the PFO-closure intervention using a double-disc device.

Dynamic computed tomography angiography (CTA) imaging provides additional diagnostic value in characterizing aortic endoleaks. This protocol describes a qualitative and quantitative approach using time-attenuation curve analysis to characterize endoleaks. The technique of integrating dynamic CTA imaging with fluoroscopy using 2D-3D image fusion is illustrated for better image guidance during treatment.
