Which of the following is a common artifact that can affect radiographic images?

A common artifact that can affect radiographic images includes several phenomena that can degrade image quality or lead to misinterpretation. Double exposure occurs when a film is exposed to radiation more than once before it is developed, causing overlapping images that can obscure details and confuse analysis. High contrast refers to situations where there is a significant difference in density between adjacent areas of the radiograph, which can potentially mask subtle features due to overly dark or light regions. Motion blur arises when there is movement during the exposure, resulting in a loss of sharpness and detail, making it difficult to discern critical structural information.

All of these artifacts can compromise the quality of radiographic images, making the option that encompasses them all the most accurate answer. Understanding these artifacts and their effects on image quality is crucial in radiographic testing, as it aids in ensuring more reliable and interpretable results.
