胸片DR后处理在特发性肺间质纤维化诊断中的应用

目的 分析胸片DR后处理功能在特发性肺间质纤维化（IPF）诊断中的作用。方法 对经确诊为IPF的患者胸片在计算机上对图像进行一系列后处理后，由3位放射诊断医师对处理前后的胸片DR进行比较分析及评价。结果 IPF患者胸片DR后处理前影像表现：纤维化条索影21例（75．0％），云雾状磨玻璃16例（57．1％），粟粒状影10例（35．7％）；结节状影12例（42．9％）；网格状、蜂窝状影14例（50．0％）；IPF患者胸片DR处理后影像表现；纤维化条索影26例（92．9％）；云雾状磨玻璃23例（82％）；粟粒状影22例（78．6％）；结节状影13例（46．4％）；网格状、蜂窝状影21例（75．0％），（P〈0．001）。结论 运用胸部DR后处理软件进行分析，能提高IPF的征象显示率，有助于提高诊断。

The Effect of Digital- ray Postprocess in Diagnosis of IPF

Objective To evaluate the value of DR post process in diagnosis of IPF.Methods 28 cases with IPF were performed DR .The chest radiographs after postprocess were compared with pre-postproess films and analysed by three radiologists.All cases were confirms by pathological findings.Results The chest films pre-postprocess showed: 21cases of fibrilliform(75.0%).16 cases of cloudy,ground-glass infiltration(57.1%);10 cases of military(35.7%);12 cases of nodule(42.9%);14 cases of reticulations and honeycomb formation(50.0%);The chest films after postprocess showed:26 cases of fibrilliform(92.9%);23 cases of cloudy,ground-glass infiltration(82.1%);22cases of military(78.6%);13 cases of nodules(46.4%);21cases of reticulations and honeycomb formation(50.0%).(p<0.01).Conclusions It can improve IPF imagine sign display rate and help improve diagnosis with using chest DR postprocess software to analysis.
