What is the difference between a MRI scan and a CT scan?
What is the difference between a CT scan and an MRI? A CT scan uses X-rays to create detailed pictures of organs, bones, and other tissues. … An MRI also creates detailed pictures of areas inside the body, but it uses radio waves and a powerful magnet to generate the pictures, so this process is radiation free.
What is an MRI scan used to diagnose?
MRI can be used to detect brain tumors, traumatic brain injury, developmental anomalies, multiple sclerosis, stroke, dementia, infection, and the causes of headache.
What is a CAT scan used to diagnose?
CT scans can detect bone and joint problems, like complex bone fractures and tumors. If you have a condition like cancer, heart disease, emphysema, or liver masses, CT scans can spot it or help doctors see any changes. They show internal injuries and bleeding, such as those caused by a car accident.
When would you use an MRI over a CT scan?

What can a CT scan miss?
Imaging tests usually can’t tell if a change has been caused by cancer. CT scans can produce false negatives and false positives. CT scan can miss cancer, or miss tumors in other areas of the body. CT scans are proven to be less effective at diagnosing cancer than PET/CT.
Is a CT scan better with or without contrast?
CONTRAST MEDIA: CT scans are most frequently done with and without a contrast media. The contrast media improves the radiologist’s ability to view the images of the inside of the body. Some patients should not have an iodine-based contrast media.

Magnetic resonance imaging produces clearer images compared to a CT scan. In instances when doctors need a view of soft tissues, an MRI is a better option than x-rays or CTs. MRIs can create better pictures of organs and soft tissues, such as torn ligaments and herniated discs, compared to CT images.
Can I request MRI instead of CT scan?
Doctors might order MRIs instead of CTs when they need to create more accurate and detailed images. Physicians typically order MRI scans to diagnose issues with bones, joints, and organs, especially those that affect the: Brain.
What can a CT scan show that an MRI Cannot?
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.
Which is better for back pain MRI or CT scan?
A CT scan is better than an MRI for imaging calcified tissues, like bones. CT scans produce excellent detail used to diagnose osteoarthritis and fractures. Joseph Spine is an advanced center for spine, scoliosis and minimally invasive surgery.
Why would a doctor order a CT scan?

CT Scans, on the other hand, can be used to image (in great detail) soft tissue, bone, and blood vessels, and do all of this at the same time. … Ultrasound is often used to image muscles, internal organs, tendons, etc.
Is MRI or CT scan better for liver?
Such survey examinations are best undertaken with a contrast-enhanced CT study since CT has high sensibility (93%) and specificity (100%) for detecting hepatic metastases . While US and MRI also have similar accuracy, CT is preferred because it out-performs US and MRI for evaluating the extra-hepatic abdomen .
