Introduction (2-3 paragraphs) Interstitial Lung Disease (ILD) represents a heterogeneous group of diffuse parenchymal lung diseases (DPLDs) involving the lung interstitium - the tissue and space around the alveoli. ILD encompasses over 200 distinct disorders including Idiopathic Pulmonary Fibrosis (IPF), Non-Specific Interstitial Pneumonia (NSIP), Hypersensitivity Pneumonitis (HP), Sarcoidosis, Connective Tissue Disease-associated ILD (CTD-ILD), and Cryptogenic Organizing Pneumonia (COP), among others. High-Resolution Computed Tomography (HRCT) of the chest has emerged as the gold-standard imaging modality for evaluation of ILD, superseding conventional chest radiography due to its superior spatial resolution and ability to characterize subtle lung parenchymal abnormalities. HRCT enables detection of patterns such as honeycombing, ground-glass opacities (GGO), reticulation, traction bronchiectasis, and nodules, which are pathognomonic of specific ILD subtypes. In India, ILD is an under-recognized cause of morbidity and mortality. The incidence is estimated at 6–10 per 1 lakh population per year. Late diagnosis, lack of awareness, and limited access to specialized investigations contribute to poor outcomes. HRCT, when combined with clinical findings and pulmonary function tests (PFTs), allows clinicians to establish a confident diagnosis without the need for surgical lung biopsy in many cases. The present study aims to systematically evaluate HRCT patterns in ILD patients and correlate these findings with clinical and functional parameters. ### 2. Review of Literature Webb WR et al. (1988) were among the first to demonstrate the superior diagnostic yield of HRCT over conventional CT and chest radiography in diffuse lung diseases. Subsequent studies established HRCT as the investigation of choice for ILD. The American Thoracic Society (ATS) and European Respiratory Society (ERS) guidelines (2002, updated 2014 and 2022) have standardized HRCT pattern recognition for IPF diagnosis. The Usual Interstitial Pneumonia (UIP) pattern on HRCT - characterized by bilateral, predominantly basal and subpleural honeycombing with or without peripheral traction bronchiectasis - can establish a diagnosis of IPF without biopsy. Raghu G et al. (2022) published the updated ATS/ERS/JRS/ALAT Clinical Practice Guidelines for IPF, incorporating HRCT as a central diagnostic pillar with specific pattern criteria. Johkoh T et al. (2020) updated the HRCT classification incorporating UIP, NSIP, DIP, RB-ILD, COP, and AIP patterns with detailed morphological descriptors. Indian studies by Sharma SK et al. reported IPF as the commonest ILD subtype in North India, while CTD-ILD was more prevalent in women. HRCT sensitivity for UIP pattern has been reported at 90-96% with specificity of 90-96% in multi-reader studies. Research gap: There is limited Indian data specifically from Gujarat/Western India on the spectrum of HRCT patterns in ILD patients and their clinico-radiological correlations, warranting a regional study. ### 3. Research Objectives Primary Objective: - To evaluate HRCT patterns in patients with suspected Interstitial Lung Disease at NMCRC Visnagar Secondary Objectives: 1. To classify ILD subtypes based on HRCT patterns (UIP, NSIP, DIP, COP, HP, AIP, Sarcoidosis, others) 2. To correlate HRCT findings with clinical features (age, sex, symptoms, duration, associated comorbidities) 3. To correlate HRCT findings with Pulmonary Function Test (PFT) parameters 4. To determine the diagnostic accuracy of HRCT in establishing ILD diagnosis ### 4. Hypothesis H0 (Null): There is no significant correlation between HRCT patterns and clinical/PFT findings in patients with ILD. H1 (Alternate): There is a significant correlation between HRCT patterns and clinical/PFT findings in patients with ILD. ### 5.
