A practical analysis to high-resolution CT diagnosis of diffuse lung diseases

Abstract

Background & Methods: The aim of the study is to analyse the high-resolution CT diagnosis of diffuse lung diseases. Data for the study were collected from patients referred to the Department of Radio diagnosis, G.R.M.C Gwalior for evaluation subjected to HRCT. A cross sectional study performed in >30 years of patients among both sexes were included in the study. They were evaluated with High Resolution Computed Tomography. Results: Out of 160 patients, 9.4% had chest discomfort, 51.9% had cough, 11.3% had fatigue, 18.1% had Shortness of breath and 9.4% had weight loss type of symptoms observed during the study. Conclusion: Diffuse lung disease mainly affects the middle age group and shows female predominance. Diffuse interstitial lung diseases are associated with smoking and chullah. It is also associated with various types of connective tissue disorders. Chest radiography is the first imaging investigation used to evaluate diffuse interstitial lung disease. It is helpful in assessing the pattern of lung disease, i.e., reticular, nodular, ground glass, honeycombing, and traction bronchiectasis. However, it has several limitations, such as obscured or hidden lung zones and limited contrast resolution, which impair sensitivity to subtle alterations in lung density (e.g., ground glass attenuation).
