What is the typical duration of a standard MRI scan?

A standard MRI scan typically lasts between 15 to 90 minutes, which accounts for the time required to properly position the patient, obtain the necessary images, and process the data. MRI scans can vary in duration due to several factors, including the type of MRI being performed, the area of the body being scanned, and the specific imaging protocols utilized.

For instance, a simple scan, such as a knee MRI, may be completed more quickly, while more complex scans involving multiple sequences or larger areas of the body, like the brain or spine, can take longer to ensure comprehensive coverage and high-quality images. The flexibility in timing allows healthcare providers to adjust the duration based on individual patient needs and specific diagnostic requirements, enhancing the overall effectiveness of the imaging process.

Other durations provided in the options are less common. Scans lasting 1 to 2 hours or over 2 hours would typically indicate specialized or significantly detailed examinations that are not standard practice and may imply additional factors such as patient comfort issues or complicated procedures that would not generally apply to standard protocols.
