Pinpoint the location of a tumor, infection or blood clot. Your doctor may recommend a CT scan to help: Diagnose muscle and bone disorders, such as bone tumors and fractures. That electrical impulse can only be seen by wires that can measure that electrical impulse. In fact, when you have epileptic activity in your brain, you cant see it with any imaging methods such as a CAT scan or MRI. An MRI is highly adept at capturing images that help doctors determine if there are abnormal tissues within the body. What the EEG measures is very different than what other tests, like CAT scans or MRIs measure. However, a CT scan is faster and can provide pictures of tissues, organs, and skeletal structure. They show internal injuries and bleeding, such as those caused by a car accident.īoth MRIs and CT scans can view internal body structures. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. Similarly, what can CT scans detect? CT scans can detect bone and joint problems, like complex bone fractures and tumors. Both MRI and CT are used to produce images of the area of the body where the tumor is located, which can aid an oncologist may use in determining the best treatment options.

This is because the EEG only shows brain activity during the time of the test. Even someone who has seizures every week can have a normal EEG test. Approximately one-half of all EEGs done for patients with seizures are interpreted as normal. Regarding this, why do I need a CT scan after an MRI?Īfter a physician initially spots a tumor, cancer patients may undergo further testing to help their oncologist stage and monitor their cancer. A normal EEG does not mean that you did not have a seizure. MRI scanners may cause a safety issue due to its strong magnets. MRIs provide more detailed information about the inner organs (soft tissues) such as the brain, skeletal system, reproductive system and other organ systems than is provided by a CT scan. CT scans use radiation (X-rays), and MRIs do not.
