A radiologist interpreting chest roentgenograms of critically ill patients sees many objects of plastic and metallic density. There are newer devices with which many radiologists are not familiar. These include venous catheters, flow-directed pulmonary artery catheter, left heart intraaortic assist balloon, pulmonary artery and left atrial catheters inserted during surgery, and right atrial and right ventricular epicardial pacing wires inserted during surgery.
This presentation is intended to familiarize the radiologist with the appearance, function, and proper position of these newer devices.
