From: 68Ga-DOTATATE PET imaging in clinically non-functioning pituitary macroadenomas
Coronal T1-weighted contrast-enhanced MRI and fused PET/MR images of a 68Ga-DOTATATE PET-positive (a, b) and PET-negative (c, d) NFMA. The colour bars represent SUV. a MRI shows a pituitary macroadenoma (asterisk) located laterally in the sella with an invasion of the left cavernous sinus. b After fusion with PET, intense uptake is seen in the NFMA (SUVmean 5.7) as well as physiological uptake in the pituitary gland on the right side of the adenoma. c In this case, the largest part of the adenoma (asterisk) is located on the right side of the pituitary stalk. d The fused PET/MRI shows no uptake in the NFMA (SUVmean 1.1) and moderate physiological uptake in the pituitary gland situated on top of the adenoma
