Photon-counting CT, the innovative and promising generation of CT detectors, has, for the first time, demonstrated the ability to accurately quantify fat content even in the presence of iron overload

    An in vitro phantom study has recently evaluated the ability of photon-counting CT (PCCT) to provide simultaneous estimates of fat and iron deposits, thereby allowing separate quantification of the fat fraction, essential for diagnosing several obesity-related conditions such as liver steatosis. Conducted on two phantoms containing various amounts of fat and iron, with added contrast material to mimic liver attenuation, the assessment involved comparing PCCT performance with that of dual-energy CT, MR spectroscopy and 3T MRI. PCCT-based estimation of fat content was robust, independent of iron deposition. Additionally, PCCT offers several technical advantages over the other imaging modalities used in this study.
