What term describes disturbances that reduce image clarity?

Explanation:
Noise describes random fluctuations in the image signal that obscure structure and reduce image clarity. It isn’t tied to a specific pattern or source, but it degrades contrast and resolution across the whole image. Artifacts are distortions that misrepresent anatomy, speckle is a characteristic granular texture from interference, and clutter refers to unwanted echoes near the region of interest. Because the question points to general disturbances that blur the image, noise is the best fit.
