【摘要】：目的探讨CT多平面重组技术在诊断肿瘤患者化疗后继发肺部真菌感染中的价值,以期早期诊断,提高诊断正确率,降低医院感染率,提高临床治疗效果。方法选取2012年1月-2014年3月95例肿瘤化疗后继发肺部真菌感染患者为研究对象,均采用CT薄层扫描,原始数据采用多平面重组技术作各个方向的图像重建,观察在影像学上的形态表现,同时和横断位上进行比较。结果在经CT多平面重组技术重建的各层面和常规横断位进行比较,横断位显示支气管征13例占13.68%、深分叶征43例占45.26%、胸膜凹陷征57例占60.00%、磨玻璃5例占5.26%、大片实变15例占15.79%、片状阴影18例占18.95%、空气半月征5例占5.26%,CT多平面重组技术处理后结果支气管征38例占40.00%、深分叶征56例占58.95%、胸膜凹陷征46例占48.42%、磨玻璃38例占40.00%、大片实变37例占38.95%、片状阴影39例占41.05%、空气半月征49例占51.58%,各项结果比较差异均有统计学意义(P0.05),而在短毛刺征上比较差异无统计学意义。结论 CT多平面重组技术能早期诊断出肿瘤化疗后继发肺部真菌感染,有助于临床诊治。
[Abstract]:Objective to investigate the value of CT multiplanar recombination in the diagnosis of pulmonary fungal infection secondary to chemotherapy in patients with tumor, so as to improve the diagnostic accuracy and reduce nosocomial infection rate. Methods from January 2012 to March 2014, 95 patients with pulmonary fungal infection after chemotherapy were selected as the study objects, all of them were scanned by CT thin layer scan, and the original data were reconstructed by multi-planar reconstruction technique in all directions. At the same time, the morphologic features were compared with those in transverse position. Results the results were compared between the different levels of CT multiplanar reconstruction and conventional transection. Transverse position showed bronchial sign in 13 cases (13.68), deep lobular sign in 43 cases (45.26), pleural indentation sign in 57 cases (60.005), grinding glass in 5 cases (5.26%), extensive consolidation in 15 cases (15.79%), flake shadow in 18 cases (18.95%) and air semilunar sign (5 cases) in 5.26CT multiplanar reconstruction technique. Results after treatment, bronchial sign accounted for 38 cases, deep lobular sign 56 cases 58.95 cases, pleural depression sign 46 cases 48.42 cases, grinding glass 38 cases 40.005%, large consolidation 37 cases 38.95%, flake shadow 39 cases 41.055.The air semilunar sign 49 cases 51.58 cases. The results are all different. There was statistical significance in P0.05, but there was no significant difference in short burr sign. Conclusion CT multiplanar recombination technique can early diagnose pulmonary fungal infection secondary to chemotherapy. It is helpful for clinical diagnosis and treatment.
