Methods 50 cases of clinically suspected microadenoma were examined with dynamicenhanced MR imaging, and standard imaging with unenhanced and contrastenhanced spinecho sequences were obtained. The threesequences were evaluated retrospectively and graded for glandlesion contrast conspicuity, lesion, homogeneity, and delineation of lesion margin.
