Answer

Blooming artifacts can cause small high-contrast structures such as stents and calcium to appear larger than they are. [4] Edge-enhancing kernel filters can decrease blooming artifacts and may be helpful for evaluating a stent lumen, although image noise is increased.

Blooming artifact: Multiplanar reconstruction (MPR Blooming artifact: Multiplanar reconstruction (MPR) CT image demonstrates blooming artifact from a left anterior descending (LAD) artery stent. The stent lumen is poorly visualized secondary to this artifact.
