Abstract

Abstract: We compare 18F-FDG PET/CT and 99mTc 3PRGD2 SPECT/CT scans in a case of histologically proved pituitary metastases. The ratio of tumor to cerebellum (T/C) of 99mTc 3PRGD2 SPECT is much higher than that for 18F-FDG PET. We then conduct the same scans for a pituitary adenoma patient for better comparison. The T/C of 18F-FDG is not able to differentiate pituitary metastases from pituitary adenoma. However, The T/C of 99mTc 3PRGD2 observed in pituitary metastases was higher than that in pituitary adenoma.
