Spectral computed tomography parameters of primary tumors and lymph nodes for predicting tumor deposits in colorectal cancer

Figure 4 Receiver operating characteristic curves of the quantitative parameters used for the differential diagnosis of tumor deposits+ and tumor deposits- patients. The areas under the curve of arterial phase-normalized iodine concentration-lymph node-to-primary tumor ratio was the highest at 0.812 (sensitivity: 0.879, specificity: 0.648, cutoff value: 1.145). AP: Arterial phase; VP: Venous phase; NIC: Normalized iodine concentration; LN: Lymph node; T: Primary tumor; NTR: Lymph node-to-primary tumor ratio.
