Findings of High Resolution Computed Tomography in Patients Presenting with Signs and Symptoms of Interstitial Lung Disease Having Normal Chest X-Ray

Background: Interstitial lung Disease is a general category that includes many different lung conditions. This study aimed to compare the chest X-rays and HRCT for clear diagnosis of ILD. Objectives: To rule out the findings of high resolution computed tomography in patients presenting with signs and symptoms of interstitial lung disease having normal chest x-ray. Methods: The study was conducted in the department of Radiology, Gulab Devi Trust Teaching Hospital and its duration was of three months from September 2019 to November to 2019. Results: Out of 148 patients, there were 65 (43.9%) males and 83 (56.1%) were females, with the mean age of 55.89 ±14.39 years. Patchy ground glass appearance 92.6%, Honey Comb Appearance 45.9%, Centri lobular CT 29.1% and Parenchymal appearance 24.3% were the high scoring variables of HRCT and were also most frequent in the patients presented with ILD. While Pleural Effusion 4.7%, Consolidation 2.7%, and nodules 12.8 % were found the less frequent variables. Conclusion: After having normal chest X-ray and confirmation of diagnosis on high resolution computed tomography (HRCT), it can be concluded that HRCT is more accurate and highly reliable technique or diagnostic tool to diagnose interstitial lung disease as compared to chest X-ray.
