Abstract:
Displacement of peripherally inserted central catheter (PICC) lines during contrast-enhanced computed tomography examinations is an underappreciated phenomenon. We report a case of iatrogenic PICC line displacement following the power injection of contrast during a computed tomography pulmonary angiogram. During the study, the PICC line was shown to move on 2 occasions, resulting in 2 nondiagnostic studies. We review the available literature on the topic and suggest possible strategies to avoid this phenomenon. Radiologists should be aware of PICC line migration, and it should become common practice to review the catheter tip position after computed tomography examinations.

Computed Tomography
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Pulmonary Angiogram
A Pulmonary Angiogram is an invasive procedure involving injecting a contrast medium through a catheter threaded into the pulmonary artery or the right side of the heart to visualize the pulmonary vasculature. Computed Tomography (CT) scans have mainly replaced this...
