From the Research
Yes, general practitioners (GPs) can order MRI scans for their patients. GPs have the authority to request various diagnostic imaging tests, including MRIs, when they believe such tests are clinically necessary for diagnosis or treatment planning 1. The process typically involves the GP completing a referral form detailing the patient's clinical history, symptoms, and the specific reason for the MRI request.
Key Considerations
- The referral is then sent to a radiology department or imaging center where the scan will be performed.
- However, there may be some limitations depending on local healthcare systems and insurance requirements.
- In some regions, certain specialized MRI scans might require referral to a specialist first, or there may be specific clinical criteria that need to be met before approval.
- Additionally, wait times for GP-ordered MRIs can sometimes be longer than those ordered by specialists, depending on the urgency indicated and local healthcare resources.
- GPs often consider factors such as clinical necessity, cost-effectiveness, and alternative diagnostic approaches before ordering an MRI, as these scans are expensive resources within healthcare systems.
Evidence Supporting GP-Ordered MRI Scans
- A study published in the Journal of primary health care in 2019 found that GPs who participated in clinical musculoskeletal training and used decision support guidance made appropriate MRI referrals, with 86% of referrals considered appropriate 1.
- Another study published in the Journal of clinical medicine in 2021 found that MRI findings often altered management in acute spinal cord injury, including timing of surgery, decision to operate, and surgical approach 2.
Limitations and Future Directions
- While the evidence supports the ability of GPs to order MRI scans, there may be variations in practice depending on local healthcare systems and insurance requirements.
- Further research is needed to determine the optimal timing, effect on outcomes, cost-effectiveness, and utility of MRI scans in different clinical contexts.
