Ten obese patients (BMI 30 - 39.9 kg/m2) with ultrasound and CT-verified non-alcoholic fatty liver disease (NAFLD). Subjects will be recruited from the Swedish CArdioPulmonary bioImage Study (SCAPIS) in Gothenburg. The participants in this study (50-65-year-old men and women) are randomly recruited from the Swedish Population and Address Register. Currently, 1050 subjects have been analyzed and 5000 additional subjects will be analyzed over the next 2 years. By January 2015, over 2000 subjects have been analyzed. Each subject is extensively phenotyped over two days. This includes extensive blood samples, anthropometry, carotid and liver ultrasound, and a CT examination that includes coronary calcium score, CT angiography of coronary arteries, thoracic aorta, and assessment of epicardial fat, liver fat, and subcutaneous abdominal fat.
