18F-FDG hrPET–positive tumors had an attenuated response to CRH stimulation. All 18F-FDG hrPET–positive tumors had an attenuated response, specifically, less than 180% change in ACTH level during CRH stimulation test. The red line demonstrates cutoff at 180% change that separates the 18F-FDG hrPET–positive tumors from negative tumors.
