 Transient hepatic attenuation differences

Transient hepatic attenuation differences (THAD) refer to a phenomenon observed in imaging studies, particularly in computed tomography (CT) scans of the liver. THAD is characterized by differences in the attenuation (or density) of liver tissue in certain areas, which can be temporary and may change over time. These differences can be associated with various conditions, including: 1. **Fatty liver disease**: Areas of the liver may exhibit reduced attenuation due to the presence of fat.
