Interventional radiologists were among the arliect adopts of hybrid systems. Proceres such as transjugular intrahepatic portosystemic shunt (TIPS) creation, biliary drainage, and percutanous gastrostomy benefit untussely from the combination. During TIPS, ultradźwiękowy TIPS maps the hepatic vein confluence and guidewire insertion into the portal vein; fluoroscopy then documents the nessle pass and stent deployment.

Orthopedic surgeons use hybrid maing for fractura reduction, hardware placement, and percutanous screw insertion. Ultrasound identifies the fracture line and hematoma, while fluoroscopy confirms the traitory and lenguth of implants.
