CT investigations of 783 cases of brain tumors, which were covered by histology, were checked with regard to frequency and configurations of calcifications. As expected the calcifications were detected more frequently by CT than by conventional radiology because of higher resolution. Most frequently calcifications were detected in craniopharyngeomas (72%) and in oligodendrogliomas (51%). The calcifications shown by CT can be changed by variation of technical parameters. Certain patterns of calcifications can be differentiated, if constant and best technical conditions are used. One single pattern cannot be specific. A homogeneous calcification of the tumor as a whole has been observed in meningeomas only. For other brain tumors calcifications are useful for the diagnosis, if localisation, density, and reaction of the surrounding tissue after injection of contrast medium and clinical data are known.
对783例经组织学证实的脑肿瘤病例进行CT检查，以确定钙化的频率和形态。正如预期的那样，由于CT具有更高的分辨率，因此比传统放射学更频繁地检测到钙化。钙化最常见于颅咽管瘤（72%）和少突胶质细胞瘤（51%）。CT显示的钙化可通过改变技术参数而改变。如果使用恒定且最佳的技术条件，可以区分某些钙化模式。单一模式并不具有特异性。仅在脑膜瘤中观察到肿瘤整体均匀钙化。对于其他脑肿瘤，如果已知钙化的位置、密度、注射造影剂后周围组织的反应以及临床数据，钙化对诊断是有用的。
