What can image distortion best be described as?

Image distortion refers to alterations that cause anatomy to appear differently than its true form in terms of size and shape. When considering distortion, misrepresentation is key; it indicates that the anatomy does not maintain its accurate shape as it should appear in a proper, undistorted image. This misrepresentation can occur alongside a change in size, where the anatomy may also appear enlarged or reduced incorrectly.

Thus, the definition of image distortion encompasses both the enlargement of anatomical structures and the misrepresentation of their shape. This is why the correct characterization includes both aspects, making the comprehensive understanding of distortion critical for ensuring accurate imaging and diagnosis in medical contexts. Knowing both elements emphasizes the importance of precise imaging techniques and quality control in radiography.
