Introduction to Magnetic Resonance Imaging (MRI)

The video tutorial explains MRI technology, highlighting its superior contrast in imaging soft tissues compared to CT scans and X-rays. It covers the history of MRI, from its first image in 1973 to its application in human studies by 1977. Initially called nuclear magnetic resonance imaging, the term 'nuclear' was dropped to improve public acceptance. The video also discusses the evolution of MRI machines, addressing patient comfort issues like claustrophobia with newer models offering larger bores and faster scan times.

What is one of the main advantages of MRI over CT scans and X-rays?

• It is less expensive.

• It uses less radiation.

• It provides greater contrast between soft tissues.

• It is faster to perform.

In which year was the first MRI image published?

• 1980

• 1895

• 1977

• 1973

Why was the term 'nuclear' dropped from 'nuclear magnetic resonance imaging'?

• It was trademarked by another company.

• Doctors feared it would not be accepted by the public.

• It was not scientifically accurate.

• It was too long to pronounce.

What is a common issue patients face during MRI scans?

• Loud noises

• Long recovery time

• Claustrophobia

• High radiation exposure

How have newer MRI machines improved the scanning experience?

• By reducing the cost of scans

• By eliminating the need for a technician

• By using less electricity

• By having larger bores and faster scan times
