What is hypoenhancement?

Answer 1

Hypoenhancement refers to a region in medical imaging, particularly in computed tomography (CT) or magnetic resonance imaging (MRI), where a specific area appears less enhanced or less bright compared to surrounding tissues after the administration of a contrast agent. This phenomenon can indicate various conditions, such as tumors, abscesses, or areas of ischemia, depending on the context and the specific characteristics of the hypoenhanced region. It is an important diagnostic feature that can aid clinicians in identifying and evaluating pathological changes in tissues.
