Difference between MRI and CT Scan

Mri’s and Ct scans are both medical imaging procedures used to diagnose issues in the body. Both procedures use different types of radiation to produce images of the inside of the body. However, there are some key differences between these two scans. The most notable difference is that MRIs use magnets while CT scans use x-rays. This means that MRIs are better at imaging soft tissues, while CT scans are better at imaging bones. MRI and CT scan results can also be interpreted differently by doctors, so it is important to understand the difference before undergoing one of these tests.

What is MRI?

MRI (magnetic resonance imaging) is a medical imaging technique that uses magnetic fields and radio waves to create detailed images of the human body. MRI is a non-invasive procedure, which means it does not require any surgery or injections. MRI can be used to image many different parts of the body, including the brain, spine, joints, and organs. MRI is often used to diagnose conditions such as tumors, strokes, and degenerative diseases. MRI is also used to guide surgeries and other procedures. For example, MRI can be used to help surgeons locate a tumor before surgery or to help guide a needle during a biopsy. MRI is a safe and painless procedure that has few side effects.

What is CT Scan?

CT Scans, or computed tomography scans, are a type of diagnostic imaging test that uses x-rays and computers to create detailed images of the inside of the body. CT Scans can be used to detect a wide variety of conditions, including tumors, infections, and bone fractures. They can also be used to guide biopsies and other types of medical procedures. CT Scans are generally safe, but they do carry a small risk of radiation exposure. CT Scans are typically covered by insurance, but some patients may have to pay a co-pay or deductible.

Difference between MRI and CT Scan

MRI and CT scans are both types of medical imaging tests. MRI stands for magnetic resonance imaging and uses radio waves and a strong magnetic field to produce detailed images of the body. CT stands for computed tomography and uses X-rays to create cross-sectional images of the body. MRI is better at detecting subtle differences in tissue and can provide more detailed images of organs, while CT is better at showing detailed bone structures. MRI is also better at detecting certain types of tumors, while CT is better at detecting lung cancer. MRI is generally more expensive than CT, but both tests are typically covered by insurance.


CT scans are a type of medical imaging that uses X-rays to create cross-sectional images (often called slices), while MRI scans use magnets and radio waves. Both have their advantages and disadvantages, which your doctor can help you decide between based on your specific needs. Whichever scan you choose, make sure you go to a reputable facility with experienced staff who will ensure that you receive the best care possible.
