Introduction and Aim: The CAP (Controlled Attenuation Parameter) function of FibroScan® is a new non-invasive diagnostic tool that allows the quantification of hepatic steatosis at the same time as elastometry. It calculates the attenuation of ultrasonic signals. The aims of our study are to determine the role of CAP values in predicting liver steatosis in patients with chronic liver diseases, and to determine factors associated with the presence of steatopathy.

Methods: Prospective, cross-sectional study, which was monocentric extending over 1 year. A CAP measurement by compact 530 fibroscan was performed using the M probe, or XL probe in the case of obesity, in all patients with chronic liver disease referred for liver elastometry, whatever its etiology and severity. Liver steatosis is graded based on the percentage of fat within the hepatocytes: grade 0: < 5%, grade 1: 5% -3 3%, grade 2: 34% - 66%, and grade 3: > 66%.

Results: Hepatic steatosis diagnosed by Fibroscan's CAP function is present in 40% of patients referred for evaluation of hepatic fibrosis for all causes of chronic liver disease. Severe hepatic steatosis is present in half of these patients. CAP values were significantly correlated with body mass index (p < 0.001), there was no correlation between CAP values and age, sex or etiology of hepatopathy nor with blood glucose, trigylceridemia, cholesterol level and liver enzymes.

Conclusion: The CAP is a promising imaging method for rapidly and non-invasively diagnosing liver steatosis.
