Patients’ lives at risk from needless lung scans

It is commonplace for patients with Acute Lung Injury (ALI) to be injected with a dye, known as contrast material, before undergoing a CT (computerized tomography) scan of their lungs. Contrast material helps enhance the image so that doctors can evaluate the state of a patient?s lungs. New research published in Critical Care shows that using contrast material could worsen the condition of patients suffering from ALI because it causes the lungs to fill up with fluid, making it more difficult for patients to breathe.
