多层螺旋计算机断层扫描联合磁共振成像对早期中央型肺癌及术后复发的诊断价值

目的:探讨多层螺旋计算机断层扫描(MSCT)联合磁共振成像(MRI)对早期中央型肺癌及术后复发的诊断价值。方法:选取2015年8月到2017年2月我院收治的早期中央型肺癌患者98例,所有患者均经MSCT和MRI检查。分析并对比单独MSCT的诊断结果及MSCT联合MRI的诊断结果。随访1年,观察并比较疑似复发的患者单独MSCT的诊断结果及MSCT联合MRI的诊断结果,并比较其对复发诊断的灵敏度、特异度。结果:MSCT联合MRI对早期中央型肺癌诊断的准确率、误诊率、漏诊率分别为94.90%、1.02%、4.08%,与单独MSCT诊断的82.65%、9.18%、8.16%比较,MSCT联合MRI诊断的准确率明显升高,误诊率明显降低(P0.05),而两种诊断方法的漏诊率比较差异无统计学意义(P0.05)。随访1年后,98例患者共复查122例次,共有49例复发。MSCT联合MRI诊断早期中央型肺癌患者术后复发的灵敏度、特异度分别为97.96%、93.15%,均高于单独MSCT诊断的83.67%、82.19%(P0.05)。结论:MSCT联合MRI诊断早期中央型肺癌准确率较高,且在诊断术后复发中可提高灵敏度、特异度。

The Diagnostic Value of MSCT Combined with MRI for Early Central Lung Cancer and Postoperative Recurrence

ABSTRACT Objective: To investigate the diagnostic value of multi-slice spiral computed tomography (MSCT) combined with mag- netic resonance imaging (MRI) for early central lung cancer and postoperative recurrence. Methods: 98 patients with early central lung cancer who were treated in our hospital from August 2015 to February 2017 were selected.All patients were examined by MSCT and MRI. The diagnostic results of separate MSCT and MSCT combined with MRI were analyzed and compared.Follow up for 1 year, the di- agnosis results of separate MSCT and MSCT combined with MRI in patient with a suspected relapse were observed and compared, and the sensitivity and specificity to the diagnosis of recurrence between them were compared. Results: The accuracy rate, misdiagnosis rate and missed diagnosis rate of MSCT combined with MRI were 94.90%, 1.02% and 4.08% respectively, compared with 82.65%, 9.18% and 8.16% of separate MSCT, the accuracy rate of MSCT combined with MRI diagnosis was increased significantly, and the misdiagnosis rate was decreased significantly (P<0.05), there was no significant difference in missed diagnosis rate between the two diagnostic meth- ods (P>0.05). Follow up for 1 year, 98 patients were reexamined 122 times, and 49 cases recurred. The sensitivity and specificity of MSCT combined with MRI in diagnosis of postoperative recurrence were 97.96% and 93.15%, which were significantly higher than 83.67% and 82.19% of separate MSCT (P<0.05). Conclusion: MSCT combined with MRI has high accuracy rate in the diagnosis of early central lung cancer, and it can improve sensitivity and specificity in diagnosis of postoperative recurrence.
