How to check lung fibrosis

Fibrous lesions in both lungs can be examined by CT scans of the lungs. Fibrous lesions in both lungs mainly appear as streaks or high-density patchy shadows on CT scans of the lungs. They can also be examined by pulmonary function tests, because patients with fibrous lesions in the lungs mainly show restrictive ventilation dysfunction. Double lung fiber focus is generally an old disease, mostly because the patient has had chronic inflammation or trauma, the body in the healing process of fibrous tissue hyperplasia, so show some scar tissue. Double lung fiber focus if the symptoms are not obvious, generally do not take special treatment, recheck lung CT every year. If there are obvious symptoms, such as chest tightness, shortness of breath, breathing difficulties, etc., we must take the corresponding treatment.
