摘要
目的:探讨彩色多普勒血流成像(CDFI)技术及计算机断层摄影术(CT)在眼眶炎性假瘤诊断中的应用价值。方法:回顾性分析67例眼眶炎性假瘤彩色多普勒血流成像及计算机断层摄影的结果,并与手术病理结果作对照研究,采用自身配对x^2检验对其结果进行统计学处理。结果:增殖型29眼,CDFI与CT的诊断准确率分别为44.8％,82.8％,两者有显著性差异(X^2=5.88,P<0.05)。弥漫型25眼,CDFI与CT的诊断准确率分别为84％,56％,两者有显著性差异(x^2=4.0,P<0.05)。混合型19眼,CDFI与CT的诊断准确率分别为63.2％,78.9％,两者无显著性差异(X^2=1.63,P>0.05)。对所有的病例,CDFI与CT的诊断准确率分别为63％,72.7％,两者无显著差异(x^2=1.16,P>0.05)。结论:两种影像检查方法对眼眶炎性假瘤的诊断无显著性差异,但对不同类型的炎性假瘤的诊断价值不同,增殖型CT优于CDFI,弥漫型CDFI优于CT,混合型无显著性差异。眼科学报1999;15:85—88。
Purpose:To explore the values of colour doppler flow image(CDFI) technique and computer tomographic(CT) scan in diagnosising orbital pseudotumors. Methods: CDFI and CT were used for examining 67 cases of orbital pseudotumors demonstrated with surgery and pathaology. The results were treated with self-match design Chi-square test.
Results: The diagnosis validities for 29 mass-type cases with CDFI and CT were 44.8% and 82.8%, respectively, with significant difference ( %2 = 5. 88, P < 0.05). The validities for 25 diffuse-type cases were 84.0% and 56.0% , respectively, with significant difference. ( x2 -4.0, P <0. 05). The validities for 19 mixture-type cases were 63.2 % and 78. 9 % , respectively, with no significant difference ( x2 =1-63, P >0.05).
The diagnosis validities for all 67 cases were 63.0% and 72.7% , respectively, with no significant difference ( x2=1. 16, P >0.05).
Conclusion :The diagnosis validities with both imaging methods were not different for diagnosis of orbital pseudotumors. But the values for diagnosing various pseudotumors were different. The validity with CDFI was superior to CT in diffuse type; CT was superior to CDFI in mass type; while the validity with CDFI and CT were not significant different in mixture type.
