1 The cost of an MRI machine depends upon the size of the machine. 2  Usually, you can expect to pay anywhere from $500,000 to an upwards of $1,000,000 for an MRI machine. 3  In certain cases, the MRI machine can cost $10,000,000. For a typical installation for an MRI System, expect to spend between $40,000 and $80,000. 2  Also, inquire about ongoing service costs. 3  Look for specialized engineers that can properly handle MRIâs. 4  These include reliable, operation and maintenance costs.
An open MRI machine has a larger opening compared to a standard MRI machine. Some have magnets that do not completely surround your body, as shown here. But this kind of open MRI cannot do some types of MRI scans. People who get nervous in small places (are claustrophobic) may feel better using an open MRI machine. An open MRI machine also may be easier to use for people who are very overweight or obese. But not all medical centers have this kind of MRI machine.
