目的研究颅内肿瘤的MRI、CT的 诊断价值，以提高对颅内肿瘤的诊断水 平。方法 选取2013年8月-2014年11月期 间我院收治的72例颅内肿瘤患者为研究对 象，所有患者均经手术病理确诊为颅内肿 瘤。根据其临床资料进行回顾性分析和总 结，探讨颅内肿瘤的MRI、CT诊断价值。 结果 CT检出65例，诊断正确率为75.0%， MRI检出72例，诊断正确率为100.0%，MRI 的诊断正确率明显高于CT，p＜0.05，差 异具有统计学意义。结论 CT与MRI对颅内 肿瘤的诊断具有重要的价值，其影像表现 具有一定的特征性，MRI对病变组织及肿 块的敏感性要高于CT，有助于对颅内肿瘤 做出准确的定位、定性诊断，颅内肿瘤采 用MRI诊断和鉴别，能提高诊断正确率， 值得在临床实践中广泛应用和推广。

Objective To discuss the diagnostic value of MRI and CT on intracranial tumor, and improve the diagnostic accuracy of intracranial tumor. Methods Seventy two patients with intracranial tumor admitted by this Hospital during the period from August, 2013 to November, 2014 were selected as research subjects, all patients were pathologically confirmed of intracranial tumor. The clinical data and diagnostic value of MRI and CT of intracranial tumor were analyzed and summarized retrospectively. Results Sixty-five cases were detected to suffer from intracranial tumor by CT, with diagnostic accuracy of 75.0%. A total of 72 patients were detected to suffer from intracranial tumor by MRI, with diagnostic accuracy of 100.0%, the diagnostic accuracy of MRI was significantly higher than that of CT( p<0.05), and the difference was statistically significant. Conclusions CT and MRI deliver important value in the diagnosis of intracranial tumor, the images show certain characteristics. The sensitivity of MRI in demonstrating the diseased tissue and tumor is higher than that of CT, and it helps to make a accurately localized and qualitative diagnosis. MRI is an good detection method on intracranial tumor and be worth of wide application and promotion in clinical practices.
