Quantitative analysis of skeletal muscle metastases (SMM). a Attenuation of SMM lesions and circumjacent muscle in conventional images (CI) and virtual monoenergetic images (VMI40keV). Attenuation of SMM is significantly increased in VMI40keV compared to CI. b Iodine concentration [mg/ml] of SMM lesions is significantly higher than in the circumjacent muscle. c Distribution of SMM iodine concentration. d CNR of SMM and circumjacent muscle is significantly increased in VMI40keV compared to CI. e Comparative ROC analysis for discrimination of SMM to circumjacent healthy muscle for attenuation in CI and VMI40keV as well as iodine concentration derived from iodine overlay images (IDO). f Distribution of SMM lesion size
