Seventy-four patients with tumors in the sellar region were examined by means of encephalotomography and axial computerised tomography. In nearly all cases, the localisation and expansion of tumors could be exactly determined by encephalotomography. In addition, a graduation according to the degree of hypothalamic compression was possible. In cases of density differences between tumor and brain tissue and contrast enhancement more information of the inner structure of a tumor (cystic or solid) could be obtained by computerised tomography. But in cases of missing density differences or/and contrast enhancement tumor diagnosis is easier by encephalotomography because of the high efficiency of encephalotomography. The indication for the form of operative treatment, transsphenoidal or transcranial, depends on the exact knowledge of tumor growth, especially of the degree of hypothalamic compression. Therefore, in all uncertain computerised diagnosis encephalotomography has to be undertained.
对74例蝶鞍区肿瘤患者进行了脑断层扫描和轴向计算机断层扫描检查。几乎在所有病例中，脑断层扫描都能准确确定肿瘤的定位和扩展情况。此外，还可以根据下丘脑受压程度进行分级。在肿瘤与脑组织之间存在密度差异且有对比增强的情况下，计算机断层扫描可以获取更多关于肿瘤内部结构（囊性或实性）的信息。但在不存在密度差异或/和对比增强的情况下，由于脑断层扫描效率高，通过脑断层扫描进行肿瘤诊断更容易。手术治疗方式（经蝶窦或经颅）的选择取决于对肿瘤生长情况的准确了解，尤其是下丘脑受压程度。因此，在所有计算机诊断不确定的情况下，都必须进行脑断层扫描。
