MRI Procedures and Safety Guidelines

Magnetic Resonance Imaging (MRI) is a medical imaging technique that uses strong magnets, radio waves, and a computer to create detailed images of the body's interior. It is used to diagnose various conditions such as brain bleeding, strokes, and injuries like herniated discs and torn ligaments. Before undergoing an MRI, patients must remove metal objects and inform the technologist of any implants. The scanning process involves lying still in a noisy scanner, which can be closed or open. The procedure is safe, and images are generated from energy signals in the body. After the scan, normal activities can be resumed, and if contrast dye is used, hydration is recommended to aid kidney function.

What is the main difference between closed and open MRI scanners?

• Open scanners provide better image quality

• Closed scanners are quieter

• Open scanners are faster

• Closed scanners are more narrow

During an MRI scan, why is it important to stay very still?

• To save energy

• To reduce scan time

• To ensure clear images

• To avoid discomfort

What is the purpose of using contrast dye in an MRI?

• To enhance comfort

• To reduce noise

• To speed up the scan

• To make the images clearer

After an MRI with contrast dye, why might you be advised to drink plenty of water?

• To stay hydrated

• To help remove the dye from your body

• To improve digestion

• To enhance image quality

What can you do after completing an MRI scan?
