Low dose C-arm Computed Tomography (CT), is a technology that uses flat panel detectors to acquire real-time 3D images during an interventional radiology (IR) procedure to assist with anatomic localization and procedural mapping. This study describes our low dose protocol and applications of its use at a pediatric institution. Read More

Percutaneous CT-guided biopsy and ablation are established techniques to diagnose and treat solid tumors. However, some tumors are not adequately visualized with CT, even after IV contrast administration, because of transient enhancement. Many of these “CT-occult” tumors are optimally seen on preprocedural MRI or PET scans. To enable targeting of such tumors, we developed software that fuses MRI/PET images to intraprocedural CT in real time. The software corrects for soft-tissue deformations which occur due to differences in patient positioning or motion. The fusion imaging is generated after each intraprocedural CT scan and takes advantage of all available imaging data. We report retrospective evaluation of this fusion method for pediatric interventional radiology procedures. Read More
