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)
