4. How do you prepare for a CT scan?

Sometimes, the medical practitioner will inject a dye into the patient's bloodstream or have him or her drink a substance containing the dye. This makes it easier for the radiographer to see the internal structures during the scan. The dye can cause nausea, so in such cases, individuals are asked to abstain from eating and drinking for a period beforehand. The patient will also be required to remove any metal items such as jewelry, and may also need to change into a special gown. Most patients will not be sedated, although those who are anxious about the procedure may have that option.
