适应症这一很少研究的造影的最重要适应症为用来在蝶鞍变化(○度)之前早期发现垂体微腺瘤。病变直径只有3毫米时造影改变就很显著,而CT扫描只能查出直径大于7毫米的病变。对较大的蝶鞍病变,造影可提供肿瘤向外扩张情况,确定颈内动脉虹吸部,海绵窦及海绵窦间窦(以下简称间窦)的位置 Indications The most important indication for angiography, which is rarely studied, is to detect early detection of pituitary microadenomas before the sella changes (degree). When the lesion diameter is only 3 mm, the contrast change is significant, and the CT scan can only detect lesions with a diameter greater than 7 mm. For larger sella lesions, angiography can provide tumor expansion, determine the position of the internal carotid siphon, cavernous sinus and interscaling sinus (hereinafter referred to as the sinus)
