This will be a cross-sectional descriptive study aimed at evaluating the role of high-resolution computed tomography (HRCT) in diagnosing Idiopathic Pulmonary Fibrosis (IPF).

Inclusion Criteria:

• Patients aged 18 years and above.
• Patients clinically suspected of having IPF.
• Patients referred for HRCT examination.
• Patients who provide informed consent to participate in the study.

Exclusion Criteria:

• Patients with a known diagnosis of other interstitial lung diseases.
• Patients with comorbid conditions that could mimic IPF.
• Patients who are pregnant.
• Patients with incomplete medical records or imaging studies

Idiopathic Pulmonary Fibrosis (IPF): IPF is defined as a chronic, progressive fibrotic interstitial lung disease diagnosed based on clinical evaluation, exclusion of other potential causes, and characteristic radiological findings on high-resolution CT (HRCT).
