General Information About the Test
Test Process and Preparation
No. Unlike MRI machines, CT machines are not long, enclosed tunnels but rather shaped like a wide ring (donut). Because the scan takes only seconds, patients with claustrophobia generally do not experience any issues.
It is a scan performed by administering an iodine-based contrast agent intravenously prior to the procedure, allowing tissues and blood vessels to be distinguished much more clearly. Fasting and kidney function tests (e.g., creatinine) are required before this procedure.
The CT imaging process uses X-rays and therefore involves a certain amount of radiation. However, new-generation devices feature technology designed to keep the dose received by the patient to a minimum. It is not performed on pregnant women unless strictly necessary.
In emergency department visits (e.g., suspected brain hemorrhage or trauma), CT results are evaluated by radiologists within minutes. Detailed reporting of routine or contrast-enhanced scans for outpatient clinic patients is generally completed on the same day or the next day.
