FIGURE 1. Consecutive coronal planes of non–attenuation-corrected ¹⁸F-FDG PET (upper row) and ¹¹C-CHOL PET (lower row) images. ¹⁸F-FDG images show intense uptake in primary tumor, hilar lymph node metastasis, and mediastinal lymph node metastases. ¹¹C-CHOL-PET images show mild tracer uptake in primary tumor and hilar metastasis; the mediastinal lymph node metastases are missed. Note high uptake of ¹¹C-CHOL-PET in liver and kidneys, hampering interpretation of upper abdomen.
