Dual energy computed tomography for detection of metastatic lymph nodes in patients with hepatocellular carcinoma

Figure 5 A 31-year-old male with hepatocellular carcinoma and non-metastatic lymph nodes. A: Region of interest was placed in the maximal axial section for lymph nodes (white arrow); B: Postoperative computed tomography showed that the lymph node was removed (white arrow); C: The spectrum curve of the removed lymph node in the portal phase showed a descending curve with a slope of about 0.8. The iodine concentration of the lymph node was 12.20 mg/mL. The normalized iodine concentration was 0.83.
