Background: Interstitial lung diseases are a diverse group of diseases that affect the lung interstitium and share similar clinical and radiological manifestations. They are a heterogeneous group of disorders of the lower respiratory tract that are characterized by both acute and chronic inflammation and a generally irreversible and relentless process of fibrosis in the interstitium and the alveolar walls. Material and methods: The study was conducted on patients who were clinically suspected of ILD (interstitial lung disease). The subjects underwent an HRCT scan of the thorax. The study included 100 subjects, of either sex, with clinically suspected ILD. The objective was to assess if HRCT can detect abnormalities in patients with suspected ILD. Demographic details, occupational history, smoking history as well as other history of risk factors, symptomatology, history of associated co-morbidities and conditions, and relevant investigations like chest radiograph findings were noted. HRCT scans were obtained in the supine position. Results: 9 subjects were below 30 years of age, 15 as well as 56 subjects belonged to the age groups of 30-50 years as well as 50-70 years whereas 28 subjects were above the age of 70. Of 100 subjects, 58 subjects were smokers whereas rest 42 subjects were non-smokers. 57 subjects were having diabetes mellitus, 23 were suffering from hypertension as well as 20 subjects were suffering from asthma. Majority of the subjects were farmers accounting for 30 cases, followed by those handling poultry business accounting for 12 cases. 40 subjects presented with both as well as dyspnea followed by 26 subjects who presented with cough only whereas 20 subjects who presented with dyspnea only. 14 subjects didn’t present with cough or dyspnea. Conclusion: The study concluded that HRCT is a reliable tool for determining the prognosis and assisting in patient care during follow-up visits. It lessens the requirement for a confirmatory lung biopsy as well as can help with the diagnosis of ILD and direct the surgeon in choosing the site for a lung biopsy.
