原始语种摘要: Abstract(#br)Purpose(#br)The clinical adoption of quantitative imaging biomarkers (radiomics) has established the need for high quality contrast-enhancement in medical images. We aimed to develop a machine-learning algorithm for Quality Control of Contrast-Enhancement on CT-scan (CECT-QC).(#br)Method(#br)Multicenter data from four independent cohorts [ A, B, C, D ] of patients with measurable liver lesions were analyzed retrospectively (patients:time-points; 503:3397): [ A ] dynamic CTs from primary liver cancer (60:2359); [ B ] triphasic CTs from primary liver cancer (31:93); [ C ] triphasic CTs from hepatocellular carcinoma (121:363); [ D ] portal venous phase CTs of liver metastasis from colorectal cancer (291:582). Patients from cohort A were randomized to training-set (48:1884) and...
