Molokai General Hospital’s Radiology Department provides X-rays, which use a very small dose of ionizing radiation to produce pictures of the inside of the chest. This type of imaging is used to evaluate the lungs, heart and chest wall and may be used to help diagnose shortness of breath, persistent cough, fever, chest pain or injury. Chest x-rays also assists in diagnosing and monitoring treatment for a variety of lung conditions such as pneumonia, emphysema and cancer. Chest x-rays are particularly useful in emergency diagnosis and treatment.
