垂体CT轴面扫描技术对微腺瘤的诊断价值

DIAGNOSTIC VALUE OF PITUITARY MICROADENOMA WITH COMPUTED AXIAL TOMOGRAPHY

本文复习20例正常人及38例垂体微腺瘤病人的CT表现,所有病例均采用层距、层厚1.5mm轴面扫描及冠、矢状面重建技术。30例病人垂体内可见低密度病灶,其中24例的低密度区在CT随诊中重复显示。提示垂体薄层轴面扫描及重建技术是诊断微腺瘤的有效方法。

A review was made of pituitary computed tomographic studies of 20normal persons and 38 patients with prolactin secreting microadenomas. Consecutive 1.5mm axial sections were taken through the pituitary fossa. Coronal and sagittal reconstructions were reviewed. Thirty patients had focal low density defects within the pituitary glands. 24 of the defects wcere verified by follow-up CT scans. Result of the studies shows that the thin-section axial scans with reconstructions is useful to diagnose the microadenoma.
