Wellbeing A-Z -Magnetic resonance imaging (MRI)

The video explains MRI, its full name, and why it's preferred over CT scans and X-rays for examining soft tissues. It highlights the use of contrast agents like gadolinium, noting potential kidney concerns. MRI is safer than CT and X-rays as it uses non-ionising radiation, eliminating future malignancy risks.

What does the 'N' in NMRI stand for, and why was it dropped?

• Natural; because it was misleading

• Nerve; because it was unnecessary

• Neural; because it was redundant

• Nuclear; because it sounds less appealing

Which of the following body parts can be examined in detail using MRI?

• Bones

• Soft tissues like blood vessels and brain

• Hair

• Teeth

How does MRI compare to CT scanning in terms of detail?

• Both provide the same level of detail

• MRI provides more detail than CT

• MRI provides less detail than CT

• CT provides more detail than MRI

What is a contrasting agent used for in MRI?

• To reduce the scanning time

• To enhance color contrast in images

• To increase the radiation dose

• To improve patient comfort

Why is MRI considered safer than X-rays?

• MRI uses non-ionizing radiation

• MRI is faster than X-rays

• MRI is less expensive

• MRI uses ionizing radiation
