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
