Open Versus Closed MRI
Most patients will undergo a closed magnetic resonance imaging scan. This form has been around for longer than the open version. It is the type that involves a machine and space that resembles an enclosed capsule. The strength of the magnetic field in this form is stronger, which allows them to capture more detailed images and do so faster. A closed scan can diagnose more conditions and issues than an open scan. However, there are some disadvantages. A closed scan is often a problem for patients who experience claustrophobia. In addition, larger patients may not fit in the machine, the machine is quite loud, and patients often need to stay completely still during the scan.
An open magnetic resonance imaging scan is self-explanatory. This scan takes place in an open machine. The open machine offers several advantages, including fewer issues for claustrophobic patients, being a better fit for larger patients, and more child-friendly. An open MRI also allows the technician to tilt the machine. Evidence indicates that open scans are more cost-effective, quieter, and cause fewer side effects. However, they take longer to perform and produce less detail in their images than the closed type.
