The C.T. findings of 33 intracerebral hematomas are described. During the first week intracerebral hematomas were visible as a sharply demarcated lesion with markedly increased density without contrast enhancement. Thereafter the density decreased gradually and after 30 days the density was always lower than that of cerebral tissue. Depending on the etiology of the hemorrhage, differences were found in the localization, shape and density of the lesion on the C.T. scan. Secondary mass effects could be evaluated precisely. On first interpretation, 94% of the hematomas were recognized as focal lesions (2 false negative) and 85% as intracerebral hematomas (2 false negative and 3 incorrect). False positives were absent. The review C.T. diagnosis was correct in 94%. In the diagnosis of intracerebral hematomas, C.T. was found to be superior to all other investigations both quantitatively and qualitatively. C.T. also has therapeutic consequences since the operability can be much better judged than before.
本文描述了33例脑内血肿的CT表现。在第一周内，脑内血肿表现为边界清晰的病变，密度显著增加，无强化。此后密度逐渐降低，30天后密度始终低于脑组织。根据出血病因，CT扫描显示病变在定位、形状和密度上存在差异。继发性占位效应可得到精确评估。初次解读时，94%的血肿被识别为局灶性病变（2例假阴性），85%被识别为脑内血肿（2例假阴性和3例错误诊断）。无假阳性。复查CT诊断正确率为94%。在脑内血肿的诊断中，CT在定量和定性方面均优于所有其他检查。CT还具有治疗意义，因为与以往相比，现在能更好地判断手术可行性。
