Types of Scans
There are different types like X-ray, MRI, and CT scans.
Before some scans, you might need to take a special pill.
These pills help make the pictures clearer.
They're called 'contrast agents' because they highlight areas inside you.
With these pills, scans are safer and show more details.
Always follow the doctor's instructions when taking these pills.
Not every scan needs a pill, only some special ones.
Always ask your doctor why and when you need these pills.
