More Information
Fasting helps provide clearer imaging results by preventing artifacts that food in the digestive system might create. Clear liquids like water, juice, or black decaffeinated coffee are usually allowed, but it’s essential to follow specific instructions based on the type of CT scan being performed.
Tips
A common mistake is eating or drinking too soon before the exam, which can blur the scan images. Following the specific fasting and preparation instructions properly is crucial.
