In radiologic imaging, what are "artifacts"?

Artifacts in radiologic imaging are specific types of distortions or errors that can obscure the clarity of the image being produced. They can manifest in various forms, such as unexpected streaks, shadows, or patterns that do not accurately represent the anatomical structures being imaged. These artifacts can arise from numerous sources, including equipment malfunction, patient movement, or even the positioning of the patient during the imaging process.

Understanding artifacts is critical for radiologic technologists and radiologists, as they can lead to misinterpretation of images and potentially impact clinical decisions. Being able to identify and differentiate artifacts from actual physiological findings is essential for accurate diagnosis and effective patient care.
