Narrative review demonstrates improved needle stability and targeting accuracy during CT and MRI procedures, indicating expanded utility for minimally invasive interventions.
Key Points
To review the design, capabilities, and clinical utility of six robotic systems developed for percutaneous needle-guided interventions under CT and MRI guidance.
Evaluated technical features across six robotic platforms compatible with CT, cone-beam CT, and MRI systems.
Summarized findings from experimental validation across phantom, animal, and clinical human trials.
Robotic assistance provided stable needle positioning for angulated approaches and enabled tool access inside restricted CT and MRI gantry spaces.
The evaluated systems facilitated accurate targeting of hard-to-reach lesions for biopsy and thermal ablation without requiring repeat contrast injections.
