本文报告CT诊断的颅内肿瘤111例,正确诊断率为92.80%,误诊率为7.20%.对各种肿瘤的CT表现进行讨论.肿瘤发生的部位,强化前后的CT值改变以及观察肿瘤钙化、局部骨质改变、占位效应等对诊断颅内肿瘤有一定的参考价值,尤其对肿瘤的定位诊断更为优越可靠.但由于肿瘤生物学行为复杂、同种肿瘤可有不同的CT表现、不同种肿瘤也可能表现相同,因而,不能作为定性诊断的绝对依据.
This article reports 111 cases of CT diagnosis of intracranial tumors, the correct diagnosis rate was 92.80%, the misdiagnosis rate was 7.20% .To explore the CT findings of various tumors.Tumor site, before and after CT value enhancement and observation of tumor calcification, Local bone changes, mass effect of intracranial tumors on the diagnosis of a certain reference value, especially for the diagnosis of tumor positioning more superior and reliable.But because of the complexity of the biological behavior of the tumor, the same type of tumor may have different CT findings, different Tumors can also behave the same, and therefore, can not be used as a definitive basis for qualitative diagnosis.
