摘要
目的利用多层螺旋CT的密度分辨率高、成像受控因素少的特点,探讨用多层螺旋CT冠状面重建图像取代高千伏胸片诊断尘肺。方法对100例已经确诊为尘肺病患者的同期高千伏胸片和多层螺旋CT冠状面重建图像与尘肺标准片进行对照性研究,分析尘肺病在多层螺旋CT冠状面重建图像上诊断标准。结果本组资料中56例在高千伏胸片上诊断Ⅰ期尘肺,而在多层螺旋CT冠状面重建图像上有49例符合Ⅰ期尘肺诊断标准、有5例符合尘肺病观察对象、有2例符合Ⅱ期尘肺诊断标准;39例在高千伏胸片上诊断Ⅱ期尘肺,而在多层螺旋CT冠状面重建图像上只有31例符合Ⅱ期尘肺诊断标准、有6例符合Ⅰ期尘肺诊断标准、有2例符合Ⅲ期尘肺诊断标准;5例在高千伏胸片上诊断Ⅲ期尘肺,在多层螺旋CT冠状面重建图像上5例全部符合Ⅲ期尘肺诊断标准。本组资料中各期尘肺病在高千伏胸片上小阴影的显示远不如多层螺旋CT冠状面重建图像上显示精确,特别是对Ⅰ、Ⅱ期尘肺病诊断有明显差异(P<0.01)。结论多层螺旋CT冠状面重建图像是高千伏胸片诊断尘肺病的有效补充,比高千伏胸片诊断尘肺病更为可靠。
Objective To investigate the clinical application of Multi - slice CT （MSCT） coronal reconstruction image substituting for the high kilovolt radiography in the diagnostic criteria of pneumoconiosis. Methods We compared the high kilovolt radiography with MSCT coronal reconstruction in 100 patients with pneumoconiosis and analyzed the diagnostic standards of pneumoconiosis on MSCT coronal reconstruction. Results Among 100 patients, 56 eases were diagnosed asⅠ- stage pneumoconiosis on the high kilovolt radiography, while on MSCT coronal reconstruction image,49 cases as Ⅰ-stage and 5 cases as the observed objects of pneumoconiosis,2 cases asⅡ -stage pneumoconiosis. 39 cases were in Ⅱ -stage pneumoconiosis on the high kilovolt radiography,while on MSCT coronal reconstruction image, 31 eases in Ⅱ -stage pneumoeoniosis and 6 eases in Ⅱ -stage pneumoconiosis,2 cases in Ⅲ-stage pneumoeoniosis. 5 cases of 100 patients were in Ⅲ- stage pneumoconiosis both on the high kilovolt radiography and on MSCT coronal reconstruetion image. It was more precise of displaying small shadows on MSCT coronal reconstruction than high kilovolt radiography in every phase, especially Ⅰ and Ⅱ stage in which the difference of pneumoconiosis diagnoses was very definite（ P 〈 0.01 ）. Conclusion MSCT coronal reconstruction is the effective supplement to the high kilovolt radiography in the diagnose of pneumoconiosis,and is more reliable in pneumoeoniosis diagnosing.
