Clinic and hospital records including additional background medical data such as results of echocardiograms, cardiac catheterization pathology reports etc., available and accessible.
Evaluation by a physician who determines that a High Resolution Computed Tomography (HRCT) of the Thorax and pulmonary function tests, including spirometry, lung volumes and diffusion capacity, are indicated as part of the standard clinical care.
If full lung function tests are normal imaging with a regular chest x-ray is sufficient.
* Study Population - subjects will be grouped based on the following criteria after obtaining pulmonary function tests and HRCT of the thorax -
1. COPD based on clinical assessment and spirometry showing airflow limitation i.e., (FEV1/FVC \< 0.70).
2. Interstitial lung disease (ILD) diagnosed by HRCT.
3. Control subjects presenting with pulmonary complaints evaluated by full PFTs (spirometry, lung volume and DLCO) and a chest x-ray and/or HRCT , all found to be within normal limits, .
You may not be if
* Primary or metastatic lung cancer.
* Acute pneumonia.
* Concomitant or previous diagnosis of Bronchial Asthma.
* Patients with severe chest wall deformity
* Decompensated heart failure or volume overload.
