Identify and explain
Magnetic fields and radiofrequency interactions generate signals that are processed into images.

- Patient table
- Scanner housing
Screen
Assess implants, devices, metal and other MRI-specific safety factors.
Communicate
Explain the examination and evaluate contrast or support needs as appropriate.
At the viva table
Try answering aloud, then open the suggested answer. Examiner questions vary.
01 / Does MRI use X-rays?
No. MRI does not use ionising radiation.
02 / Does an implant always exclude MRI?
No. Compatibility depends on the specific device and its conditions; unknown status requires assessment.
03 / Why restrict ferromagnetic objects?
The magnetic field can create dangerous forces and projectile risks.
04 / Is every sequence interchangeable?
No. Sequences provide different tissue contrast and answer different questions.
