What is used in MRI to change the quantum state of hydrogen atoms?

• Ultrasound

• Radio waves

• A very strong magnet

• X-rays

What is the role of radio waves in MRI?

• They are used to create a magnetic field

• They are used to detect the signals from hydrogen atoms

• They are used to destabilise the hydrogen atoms

• They are used to translate signals into an image

How are the signals from hydrogen atoms detected in an MRI machine?

• Using an X-ray detector

• Using an antenna in the tube

• Using a gamma-ray detector

• Using ultrasound waves

What does the computer do with the signals detected by the MRI machine?

• It amplifies the radio signals

• It creates a three-dimensional model

• It translates these signals into an image

• It records the signals for further analysis

Does MRI use ionising radiation?

• Yes

• No

• Only in certain conditions

• Only with additional equipment

In which planes can MRI generate an image?

• Only in the horizontal plane

• Only in the vertical plane

• Only in the sagittal plane

• In ANY plane

What type of objects are not allowed in the room during an MRI scan?

• Plastic objects

• Ferrous or electronic objects

• Wooden objects

• ID chips

Why must patients be anesthetised or heavily sedated during an MRI scan?

• To prevent allergic reactions to the MRI scan

• To reduce the cost of the scan

• To prevent any movement that can ruin the scan

• To speed up the scanning process

How long may an MRI scan take?

• Less than 30 minutes

• An hour or more
