Abstract:
10mm in diameter) which were mostly non-functional ones(63.3%), and 12 microadenomas(≤10mm in diameter) which were mostly functional ones(91.7%). Only macroadenonas had abnormal imaging in DR, DSA, while microadenomas had no change in above radiological examinations. Microadenomas appeared in low density on CT or hypointensity in MRI as the direct signs, and CT, MRI contrast enhancement raised its display rate greatly. Macroadenomas showed various contrast in the post enhancement CT or MRI. Contrast enhancement of CT or MRI were capable of delineating size, location, extent of the tumor and the remaining intact pituitary tissue. Conclusion MRI Gd-DTPA contrast enhancement scaning is the first-selecting method to diagnose the pituitary adenomas especially the clinical suspected cases.
