There are several differences between CT scans and MRIs. Usually, your doctor will decide on the best scanning tool for your situation. Here are several ways the two stand apart.
Cost: CT scans are almost half the price of MRIs. The average computed tomography scan costs around $1,200 while an MRI is about $2,000.
Speed: CT scans take much less time than MRIs. The exact time required depends on whether you need a contrast dye for the procedure, but MRIs always require more time for the scan. A typical CT scan lasts 10 minutes whereas MRIs can take up to an hour or longer.
Images: MRIs will produce sharper, more detailed results, especially of soft tissues and behind bones, which may block views on CT scans.
Sound level: MRIs tend to be very noisy, and you will get earplugs or headphones to reduce the effect on your ears. CT scans are much quieter than MRIs, and you won’t need ear protection during the procedure.
