What does a CT scan show that an MRI does not?
Both MRIs and CT scans can view internal body structures.
However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure.
An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body.
MRIs are more detailed in their images..
Is MRI better than CT scan for brain?
MRI scans usually provide a far more detailed image of the soft tissues and internal organs such as the brain, skeletal system, reproductive system and other organ systems than that provided by a CT scan. CT scans are quick and painless, although they do involve exposure to small amounts of radiation.
When would you use an MRI over a CT scan?
Expect your MRI to take at least 30 minutes while a typical CT scan may take only 5 minutes. And while CT is great for looking at a tiny bone fracture or an organ, an MRI is better for looking at soft tissue like your brain.
What does a CT scan of the brain show?

Why would you need to have an MRI after having a CT scan?

Why would a doctor order a CT scan?
Your doctor may recommend a CT scan to help: Diagnose muscle and bone disorders, such as bone tumors and fractures. Pinpoint the location of a tumor, infection or blood clot. Guide procedures such as surgery, biopsy and radiation therapy.
