A diagnosis of asbestosis will usually be made by a chest consultant following investigations which normally include x-rays and a CT Scan. If an x-ray shows some shadowing, the consultant may ask for you to have a CT scan which takes pictures of the inside of the body and provides much more information. Some conditions look similar on an x-ray to asbestosis and therefore the consultant should take a history of your asbestos exposure before diagnosing you with asbestosis.
