  1. Note—Data are the number of lesions, with the sensitivity and specificity percentages in parentheses
  2. Sensitivity refers to the proportion of the number of correctly diagnosed HCC with HBDTTs to that of all HCCs
  3. Specificity refers to the proportion of the number of correctly diagnosed hilar CCs to that of all hilar CCs
