The term "comparative imaging" is best described as evaluating different imaging modalities. This involves assessing and contrasting various imaging techniques, such as CT, MRI, ultrasound, and X-rays, to determine their effectiveness, advantages, and limitations in diagnosing and treating specific medical conditions. Understanding the strengths and weaknesses of each modality helps healthcare professionals decide which imaging should be employed for a particular patient based on clinical needs.

Other options address related topics but do not fully capture the essence of "comparative imaging." For instance, comparing patient histories focuses on patient data rather than the imaging techniques themselves. Analyzing exposure levels between patients does not directly involve the comparison of different imaging types. Lastly, examining changes in image quality pertains to a specific aspect of imaging rather than the broader evaluation of modalities.
