CT scan

CT scans use X-rays and provide detailed images of bones and organs, while MRI scans use magnets and radio waves to get images of soft tissues. CT scans are quicker but involve some radiation, while MRI scans do not use radiation but take longer.

CT scans involve radiation, and thus, it's generally recommended to avoid them during pregnancy. However, in emergency situations, a CT scan may be necessary, and appropriate precautions can be taken to minimize radiation exposure to the fetus.

The duration of a CT scan varies depending on the type and complexity of the scan. It can range from a few minutes to around half an hour.

Depending on the type of CT scan you need, your doctor/healthcare professional may ask you to avoid drinking or eating for a certain period before the procedure. It's important to follow the instructions provided by your healthcare provider.

If you have a known allergy to contrast dye, inform your healthcare provider/doctor well in advance. They can take necessary precautions or consider alternative imaging techniques that do not require contrast dye.

No, a CT scan is a painless procedure. However, you may need to lie still on a table during the scan, and some individuals may feel slightly uncomfortable due to the confined space of the scanner.
