Round CT film static artifacts: simulation of focal pathology.
Spot-like or smudge-like film artifacts produced by static electric discharges may mimic lesions when superimposed on filmed CT images. These artifacts are typically round with a dark center that fades peripherally. Automatic film loading, low atmospheric humidity, and dirty film cassettes increase production of these artifactual pseudolesions. Misdiagnosis is prevented by familiarity with the artifacts' appearance and review of images on the viewing console.
