摘要
本文总结了11例原发性垂体性侏儒患者鞍区MRI和CT检查结果。发现:MRI检查,11例患者均清楚显示垂体萎缩,以及垂体柄、垂体后叶异常;CT检查,仅可见垂体的消失,而其大小则无法评价,垂体柄显示不如MRI敏感,并且不能显示后叶。MRI较CT有更好的组织对比性。尤其是微细结构的显示,MRI更具优势。检查发现所有垂体侏儒患者MRI上均有鞍区异常。这为该病的诊断和今后治疗研究提供了重要形态学依据。
The sella MRIand CT of 11 patients with primary pituitary dwarfism (PPD) were evaluated in this study. The results revealed that MRI could find the aplasia of the pituitary and the abnormality of the pituitary stalk and pituitary posterior lobe, while CT only could show the disapperance of the pituitary and not the morphology of the pituitary and its posterior lobe. The CT scanning of the pituitary stalk was less clear than that of MRI. It is suggested that MRI has better tissue contrast and sensitivity, especially to the display of slight structure. Besides, the sella abnormality in MRI provides an important morphological basis for diagnosis and treatment of PPD.
