Apr 1, 2024 · X-ray artifacts can present in a variety of ways including abnormal shadows noted on a radiograph or degraded image quality, and have been produced by artificial means from hardware failure, operator error and software (post-processing) artifacts.
Aug 2, 2016 · Since the early days of radiology, artifacts have appeared on radiographs. Actually, the first radiograph ever taken had an artifact present, a metallic ring on the patient’s hand. Artifacts are a common cause of repeat radiographs; they often occur in unexpected places, with many peculiar internal objects being detected.
Radiographers’ scope of practice in medical image interpretation. There are three critical elements to every diagnostic imaging examination: It must be the appropriate investigation, justifi ed in the context of each person’s presenting signs and symptoms, and clinical history.
Artifactual appearances seen on a chest X-ray may be due to radiographic technique, patient factors, or the presence of external or internal non-anatomical objects. Artifact is often unavoidable, but some artifact can lead to misinterpretation of the image.
