characterizations of functional vascularity of ACTH-producing and non-functioning
pituitary adenomas are critical to identify their differences in clinics. From
this, a semi-quantitative method, i.e. three-time point method of DCE-MRI was
proposed to detail the dynamic enhanced features and thus distinguish them. The
results indicate that based on the enhancement time-signal curve, the volume
percentage of the two groups are different in the washout-type curve.
Particularly, in wash-out phase of the curve, the descending slope of
ACTH-producing is greater than that in non-functioning pituitary adenoma.
