Brain and nervous system
MRIs can detect brain problems like strokes, Alzheimer's, and brain injuries. A special type of MRI called a functional MRI (fMRI) can map brain activity by looking at blood flow in the brain.
Heart and blood vessels
MRIs can evaluate the heart's chambers, valves, and blood flow, and diagnose conditions like tumors, infections, and inflammatory conditions.
Bones and joints
MRIs can detect joint injuries or diseases, bone infections, and tumors of the bones and soft tissues.
Breast cancer
MRIs can be used with mammography to detect breast cancer, especially in people with dense breast tissue.
Prostate cancer
MRIs can detect prostate cancer and evaluate if it's spreading.
MRIs use a large magnet and radio waves to create images of the body. The MRI scanner is a large tube that contains powerful magnets. During the scan, you lie inside the tube and need to lie as still as possible. MRI scans are painless, but they can be noisy, so you wear ear plugs or headphones."

Both a CT scan machine and MRI could use modern improvements...
An MRI is essentially a spinning magnet that always needs to be on, is massive and costs like $1M. A CT scanner is simpler but produces radiation and hits you with a high dose every time you have one... you don't want to have those too often. Both seem like overkill and it would be nice to have something smaller and simpler.
