Using CMP images to distinguish AML.wovf from ccRCC. a, CMP imaging of a 59-year-old male with histopathologically proven ccRCC. Main quantitative parameter: AVT_CMP (1) = 188.93 Hu, RER_CMP (1) = 92.38, AVT_CMP (2) = 236.74 Hu, RER_CMP (2) = 115.76, HDT_CMP = 43.62 Hu, SHR_CMP = 369.35. b CMP imaging of a 55-year-old male with histopathologically proven AML.wovf. Main quantitative parameter: AVT_CMP (1) = 157.75 Hu, RER_CMP (1) = 84.22, AVT_CMP (2) = 179.96 Hu, RER_CMP (2) = 96.08, HDT_CMP = 24.29 Hu, SHR_CMP = 223.46. Generally, it is difficult to distinguish AML.wovf from ccRCC by using only one conventional ROI [ROI (1)] in CMP. However, combining a smaller ROI [ROI (2)] representing the enhancement degree and a larger ROI [ROI (3)] representing the degree of enhanced heterogeneity together can accurately distinguish them in single CMP
