Question

Quizplus · Accepted Answer

Artifacts are features in an image that are not actual anatomical structures but appear as if they are. They can mimic or mask clinical features and are often caused by technical errors during imaging. Noise is random variation in image intensity, density resolution refers to the range of gray tones that can be detected by the imaging system, and detective quantum efficiency is a measure of the efficiency of the imaging system in converting x-rays to image information. None of these directly relate to masking or mimicking clinical features.
