title: [Artefacts in the CT scan caused by surgical clips and central venous catheters and the use of new materials].
abstract: When metal clips and venous catheters have been used the computerized tomography shows artifacts, which make it computerized tomography shows artifacts, which make it difficult to have a reliable and accurate diagnosis, because the X- raying of the metal clips and the venous catheter gives radiating lines, so called streaking. We have tested new materials for the metal clips and a new polymer to replace the substance of the venous catheter with the intention that the materials should have the same density as the normal tissues. With a new metal for the clips and a new polymer for the venous catheters, mixed with metal ions, the computerized tomography does not show streaking.
