Abstract

INTRODUCTION

Alveolointerstitial involvement is a common manifestation in patients with connective tissue disorders. The aim of our study is to investigate the utility of modified TTUS scoring system compared with HRCT findings of pulmonary involvement in rheumatoid lung disease.

MATERIAL AND METHODS

Thirty one consecutive patients with a suspected diagnosis of rheumatoid lung involvement were examined with high resolution transthoracic ultrasonography for detecting of ultrasonographic comet tail signe as a ultrasonographic marker of lung involvement in alveolointerstitial involvement in rheumatoid lung disease and the results of them were compared with High resolution computed tomography as gold standard method for diagnosis of lung involvement in this patients.

RESULTS

In comparison with HRCT as gold standard method, the sensitivity, specificity, positive and negative predictive value of TTUS was 73.58%, 88.23%, 95.12% and 51.72% respectively.

CONCLUSION

Modified TTUS can be a useful imaging modality in the evaluation of even early stages of pulmonary involvement in rheumatoid lung disease.

摘要

引言

肺泡间质受累是结缔组织疾病患者的常见表现。我们研究的目的是调查改良的经胸超声评分系统与类风湿性肺病肺部受累的高分辨率计算机断层扫描(HRCT)结果相比的效用。

材料与方法

连续31例疑似类风湿性肺受累的患者接受了高分辨率经胸超声检查,以检测超声彗尾征,作为类风湿性肺病肺泡间质受累中肺受累的超声标志物,并将其结果与高分辨率计算机断层扫描作为诊断该患者肺受累的金标准方法进行比较。

结果

与作为金标准方法的HRCT相比,经胸超声(TTUS)的敏感性、特异性、阳性和阴性预测值分别为73.58%、88.23%、95.12%和51.72%。

结论

改良的经胸超声在评估类风湿性肺病肺部受累的早期阶段可能是一种有用的成像方式。
