Advanced radiological modalities such as Amide Proton Transfer weighted imaging (APTw) may be useful in probing biological tissue properties of pituitary adenomas. The objective of the present study was to examine APTw derived APT value to noninvasively and quantitatively measuring pituitary adenomas. Moreover, the correlation analysis was performed between ATP value and hormone secretion to validate the efficiency of ATP value in differentiate hormone secretion related pituitary adenomas.
