Why does it take so long to get MRI?

An MRI is suited for examining soft tissue in ligament and tendon injuries, spinal cord injuries, brain tumors, etc. CT scans are widely used in emergency rooms because the scan takes less than 5 minutes. … You can understand that the tissues are very small elements so it will take more time than CT Scan.

How long does an MRI take?

A magnetic resonance imaging (MRI) scan is a painless procedure that lasts 15 to 90 minutes, depending on the size of the area being scanned and the number of images being taken.

What takes longer CT or MRI?

Although most scans are done within 10 to 15 minutes, CT scans typically take much less time than an MRI. The scan time for CTs can take as little as five minutes, while MRI scans can take 30 minutes to an hour to complete.

Why do I feel weird after an MRI?

According to researchers at John’s Hopkins University, the magnet in MRI machines can stimulate the inner ear’s balance center, causing some patients to feel vertigo while they are inside the machine and in the minute or two after they’ve left it.
