Computed tomography as a problem solving tool in non-radiopaque central venous port systems - A report of three cases.

Central venous port systems are now routinely used in oncology. The non-functioning port system is a common issue in radiology departments. Fluoroscopy is a first-line imaging modality. The potential usefulness of computed tomography as a problem-solving tool in three complex cases with non-radiopaque central venous port systems is presented.
