Hi, and thanks for your medical question on eHealth's Ask a Doctor forum.

The usual lung screening tests are X-rays, CT scans, MRI, and PET (Positron emission tomography). All except X-rays give the result immediately if a trained person is visualizing the screen. However all these involve radiation.

The other test which can be done is a pulmonary function test. The test measures how well the lungs take in and give out air and how well they distribute oxygen into the blood. Auscultation of the chest by a trained doctor or chest specialist also often detects problems.

You can discuss this with your doctor as you are having symptoms. Hope this helps. Take care!
