A spine MRI typically takes between 30 and 60 minutes to complete, including the time required for positioning.
Here's a breakdown of factors influencing the duration:
- Region of the Spine: The specific area being imaged (cervical, thoracic, or lumbar) can affect the scan time. Imaging a larger area, such as the entire spine, will naturally take longer.
- Specific Protocol: Different clinical indications necessitate different imaging protocols. More complex protocols, requiring multiple sequences, increase the overall scan time.
- MRI Machine and Technology: Newer MRI machines with advanced technology may acquire images faster than older models.
- Patient Cooperation: Patient movement during the scan can prolong the procedure, as the technologist may need to repeat sequences to ensure image quality.
- Need for Contrast: The use of contrast dye can add a few minutes to the overall procedure.
While the scan itself is painless, it's important to note that the MRI machine is an enclosed space, which can trigger anxiety in some individuals. If you anticipate feeling anxious, discuss options with your doctor, such as anti-anxiety medication to take before the exam.
