Controlled Attenuation Parameter in Nonalcoholic Fatty Liver Disease: The Thresholds Do Matter

We read with interest a recent paper by Caussy et  al1 on a direct comparison of controlled attenuation parameter (CAP) measurements using the M versus the XL probe for the detection of liver steatosis in a well-characterized group of patients at risk of nonalcoholic fatty liver disease (NAFLD) with magnetic resonance imaging (MRI) proton density fat fraction used as the reference. A single time-point assessment clearly demonstrated that in the same participants, CAP values are significantly lower when obtained with the M probe as compared with the XL probe, even when the probe is selected according to participant’s body mass index.
