Vibration-controlled transient elastography (VCE) can accurately assess liver stiffness (i.e., fibrosis) and steatosis noninvasively, but has a high failure rate (25%) in assessing overweight patients. Now, researchers have evaluated the success and reliability of a newer VCE technology (Fibroscan 502 Touch) that includes the added ability to measure degree of steatosis, or controlled attenuation parameter (CAP).
A simultaneous assessment of liver stiffness and CAP was performed in nearly 1000 patients (mean body-mass index, 34 kg/m2) with histologically confirmed nonalcoholic fatty liver disease (NAFLD) who were participating in a prospective study. Testing was performed twice in all patients. Failure of testing was defined as the inability…
