目的探讨核磁共振成像(MRI)与 多层螺旋CT(MSCT)在诊断中央型肺癌患 者中的应用。方法 选择我院2016年1月 至2018年1月收治的疑似中央型肺癌患者 126例，均进行MRI与MSCT检查，且行手术 或穿刺活检，以病理结果为标准，比较 MRI与MSCT对中央型肺癌的诊断价值。结 果 126例患者病理显示为中央型肺癌117 例。以病理结果为准，MSCT检出中央型 肺癌107例，MRI检出中央型肺癌104例。 MSCT对中央型肺癌诊断灵敏度、特异度、 准确度、阳性预测值和阴性预测值分别 为91.45%、77.78%、90.48%、98.16%和 41.18%。MRI对中央型肺癌诊断灵敏度、 特异度、准确度、阳性预测值和阴性预 测值分别为88.89%、66.67%、87.30%、 97.20%和31.58%。结论 MRI与MSCT对中央 型肺癌均有较高诊断价值。

Objective To explore the application of magnetic resonance imaging (MRI) and multi-slice spiral CT (MSCT) in the diagnosis of patients with central lung cancer. Methods 126 cases of patients with suspected central lung cancer in our hospital from January 2016 to January 2018 were selected and examined by MRI and MSCT, t and they were given surgery or needle biopsy. The diagnostic value of MRI and MSCT for central lung cancer was compared by taking the pathological results as standards. Results Pathology showed there were 117 cases of central lung cancer among 126 patients. Taking pathological results as standards, 107 cases of central lung cancer were detected by MSCT, and 104 cases of central lung cancer were detected by MRI. The diagnostic sensitivity, specificity, accuracy, positive predictive value and negative predictive value in the diagnosis of central lung cancer were 91.45%, 77.78%, 90.48%, 98.16% and 41.18% respectively by MSCT, and were 88.89%, 66.67%, 87.30%, 97.20% and 31.58% respectively by MRI. Conclusion Both MRI and MSCT have high diagnostic value for central lung cancer.
