“Can I eat before CT scan?”

If your CT scan examination requires IV contrast administration, you might be instructed not eat or drink for 4 hours prior to the scan. To decrease the likelihood of vomiting and aspiration, some radiology practices request the patients to fast prior to administration of intravenous contrast media. If you are taking prescription medications, please discus with your doctor when to take them, as preprocedural fasting may have negative effects of hypoglycemia, specifically in the patients with diabetes mellitus.
