Fatty liver is often detected incidentally on which imaging modality?

• A. Abdominal imaging
• B. Chest X-ray
• C. EEG
• D. CT brain

Answer: (A)

Fatty liver is often found incidentally when imaging the abdomen because the liver sits in that region and its parenchymal changes are readily visible on abdominal studies. Ultrasound is commonly used and shows fatty infiltration as increased echogenicity, making the liver appear brighter than the kidney and sometimes obscuring vessels. CT can reveal lower liver attenuation relative to the spleen, and MRI can quantify fat content. Chest X-ray, EEG, and CT brain focus on thoracic structures or the brain and are not good modalities for assessing hepatic fat, so they’re unlikely to reveal this finding.
