The hyperdense right hemidiaphragm sign: a novel radiological indicator of diffuse fatty liver infiltration on non-enhanced ct

HIGHLIGHTS

• What: Observation, the authors propose a new radiological sign: the hyperdense right hemidiaphragm sign (HRHS). The authors aim to assess the utility of HRHS and compare its diagnostic performance with preexisting radiological signs. The aim of this study is to introduce HRHS as a novel radiological sign for diagnosing diffuse hepatic fat infiltration on NECT scans and to evaluate its sensitivity, specificity, positive predictive value, and negative predictive value in comparison with established NECT signs. The study shows higher specificity (98-100%) compared to the 90% specificity reported in Dendl and Schreyer`s study .
