Note the persistent extensive retroperitoneal air and metallic clips (arrowhead in B).
Metal artefact reduction algorithms using flat-panel detector CT [ 71, 72], subtraction three-dimensional CTA with the orbital synchronised helical scan technique [ 65], and advanced 3 T MRI imaging techniques [ 73] are some of the new modalities applied to reduce artefacts generated by the metallic clips, which can in turn improve the quality of the image.

To design selective radiation exposure of the right kidney, metallic clips were surgically placed in the kidney of anesthetized mice.
Another technical drawbacks are magnetic susceptibility artifacts, due to metallic clips or to the air-filled balloon, in the interface with the rectum, that could lead to an unreliable evaluation of some lesions, especially in posterior portion of the PF (false positive or unsatisfactory images).
Susceptibility artefacts from metallic clips and gas may give rise to difficulties in interpretation, although titanium clips used nowadays for cholecystectomy are not magnetic.
Comparison of unenhanced (a) and arterial-phase (b, c) CT images detected active contrast extravasation in the duodenal lumen (arrowheads) abutting the metallic clips (thin arrows), consistent with persistently ongoing arterial haemorrhage.
The abdomen was closed in layers using 4 0 sutures (Ethicon Inc., Piscataway, NJ) and metallic clips.
After repositioning of the bowel, the abdomen was closed in layers using 4-0 suturesl suturEthiconInc. Inc., Somerville, NJ) and metallic clips.
How puzzling then that the overall effect of mid-calf tailoring, with coats fastened with metallic clips and wide cropped pants, seemed more stolid than artsy.
