94例肺部局灶性磨玻璃密度结节MSCT诊断分析

MSCT Diagnostic Analysis of 94 Cases with Focal Ground-glass Opacity

目的:观察分析肺部局灶性磨玻璃密度结节(fGGO)采取MSCT诊断的方法及准确性,总结其临床诊断价值。方法:选取我院2009年8月至2011年8月经手术病理证实为fGGO的患者94例,分别对其MSCT的临床诊断资料进行回顾性分析,观察其诊断的灵敏度、特异性及准确率。结果:94例fGGO的患者中,混合性磨玻璃密度(mGGO)有70例,占74.5%,单纯性磨玻璃密度(pGGO)有24例,占25.5%,两种类型的fGGO的患者良恶性比较无明显差异性(P>0.05),无统计学意义。结论:在MSCT诊断中,"血管集束征"、"胸膜凹陷征"、"空泡征"、清楚毛糙的界面、棘状突起、分叶、类圆形皆为MSCT鉴别恶性结节的主要征象,诊断准确率高,能协助临床早期诊断,及早对症制定出合理的治疗方案,具有重要的临床诊断价值。

Objective：To observe and analyze the method and accuracy of MSCT diagnosis in focal ground-glass opacity（fGGO）, and to summarize the clinical diagnostic value. Methods：The pathologically confirmed fGGO 94 patients in our hospital from August 2009 to August 2011 were selected, retrospectively analyzed their MSCT clinical diagnostic datum, observed the diagnostic sensitivity, specificity and accuracy. Results： Of 94 cases with fGGO, there were 70 cases with mixed ground-glass opacity （mGGO）, accounted for 74.5%, 24 cases with simple ground-glass opacity （pGGO）, accounted for 25.5%, compared benign and malignant of the two fGGO types had no significant difference, P〉0.05, had no statistically significant. Conclusion：In MSCT diagnosis, vessel convergence sign, pleural indentation, vacuole sign, clearly rough interface, spines, leaf, oval are major signs the MSCT identify malignant nodules, it has high diagnostic accuracy rate, can help early diagnosis, early symptomatic develop a reasonable treatment options ,it has important clinical diagnostic value.
