In radiographic imaging, what does the term "artifact" mean?

In the context of radiographic imaging, an "artifact" refers to unwanted features or distortions that appear in an image and can compromise the quality and interpretability of the radiographic findings. Artifacts can arise from various sources, including equipment malfunction, improper technique, patient movement, or even the presence of foreign materials. Recognizing and understanding these artifacts is essential because they can mimic pathological conditions, potentially leading to misdiagnosis or unnecessary additional procedures. The term highlights the importance of quality control in imaging practices to ensure that images accurately represent the anatomy and pathology without misleading features.
