Differentiating between non-functioning pituitary macroadenomas and sellar meningiomas using ADC

open access: yesEndocrine Connections, 2020
Introduction and aim: It is difficult to distinguish between non-functioning pituitary macroadenomas (NFPMAs) and sellar meningiomas because of their overlapping imaging manifestations on routine MRI, especially in cases of meningiomas growing into the ...
