Patients with known/suspected cardiac disease were excluded from the study. All patients underwent chest X-ray and chest ultrasound, reported by two different investigators. The concordance was analyzed using Cohen's kappa value with a ‘p-value’ less than 0.05 considered statistically significant.Results Among the fifty-three patients with dyspnea, five diagnostic pathologies were evaluated. Concordance between lung ultrasound and chest X-ray for diagnosis of pneumonia, pneumothorax, acute exacerbation of COPD/severe asthma, and diffuse alveolar interstitial syndrome was found to be high with Cohen's kappa value > 0.8 (p < 0.01). Ultrasound was able to correctly diagnose more cases of pneumothorax and pulmonary edema compared with chest X-ray with sensitivity and negative predictive value of 100%. Chest X-ray was found to be superior in correctly diagnosing COPD. The difference was, however, not statistically significant. Similarly, no statistically significant difference could be inferred between the diagnostic value of ultrasound and Chest X-ray in the diagnosis of pneumonia or pleural effusion.Conclusions A high concordance was noted between ultrasound and chest X-ray for diagnosis of all pathologies studied (p < 0.01), the highest noted in pneumonia/pleural effusion and diffuse interstitial syndrome (κ = 0.9). Hence, ultrasound may be considered a complimentary imaging modality for Chest-X-ray in the evaluation of dyspnea. PB - Thieme Medical and Scientific Publishers Pvt. Ltd.
