What is an MRI?

A machine that that uses an incredibly powerful magnet for scans

Several important parts (super conducting magnet, RF coils, and gradient coils)

What do each of these do?

Common Uses

Brain

Neck

Heart

Chest

Abdomen

ect

Problems with MRI

Duration of exam

Noise from machine

Inability for people with metal implants to use scan

Smallness of machine (diameter of machine)

Ability of patients getting claustrophobia

Corrections

New ability for those with metal implants to use machine

Glass siding for machine (reduce risk of claustrophobia)

New ability of taking exam 7 times faster than before

Conclusion

Produces clearest exam results

Still in infancy (more improvements can occur)
