a–d Severe diffuse fatty liver disease. a Ultrasound image in a 58-year-old man known for intraductal papillary mucinous neoplasm (IPMN/IPMT) of the pancreas and alcoholic pancreatitis showing a hyperechoic liver compared with the right renal cortex. b CT, axial contrast-enhanced portal phase image shows a diffusely hypodense liver (42 HU) compared with the spleen (113 HU) (>25 HU difference). MRI, c axial T1-weighted in-phase and d out-of-phase images show an important signal drop of the liver on the opposed-phase image. MR images were obtained on a 1.5-T MRI system with TEs of 2.2 and 4.5 for in- and out-of-phase images respectively
