X线摄影对颅内肿瘤的诊断和定位的价值主要局限于肿瘤累及颅骨的病例。在对霍尔斯特德医生诊所100例脑瘤的X线检查结果的分析中，豪雅和我发现，只有6%的病例肿瘤投下阴影，在这些病例中，只有钙化区域才能通过X射线与正常脑组织区分开来。肿瘤侵犯蝶窦、筛窦或额窦者占9%。这种阴影是由于正常情况下所含的空气被X射线较难透过的组织所吸收。这组阴影的实际意义不大，因为可以通过破坏窦壁或窦骨隔来识别生长。
THE value of rontgenography in the diagnosis and localization of intra-cranial tumors is mainly restricted to the cases in which the neoplasm has affected the skull. In an analysis of the X-ray findings in one hundred cases of/brain tumor from Doctor Halsted's Clinic, Heuer and I 1 have shown that in only 6 per cent. of thecases did the tumor cast a shadow, and in these it was only the calcified areas that were differentiated by the X-rays from the normal cerebral tissues.In those instances (9 per cent. of our cases) in which a tumor (has en-croached upon the sphenoid, ethmoid or frontal sinus, the invading portion casts a shadow in the r6ntgenogram. Such shadows are due to the displace-ment of the normally contained air by tissues which are less pervious to the X-ray. This group of shadows is of minorpractical importance because the growth can be recognized by the destruction of the walls or bony septa of the sinuses.
