Pituitary microadenomas are commonly visualized as well-defined lesions that enhance less than the normal pituitary gland, but it is not clear about the enhancement pattern of microadenomas. Our work is to evaluate the TIC type and the five parameters extracted from time-signal curves of DCE-MRI in the normal pituitary gland, microadenoma and the Rathke’s cleft cyst.
