When you undergo a brain scan or a specialized treatment, a team of experts works behind the scenes. A review of practices across 26 countries looked at how these teams are organized for different types of tests, including EEG, MRI, and others like TMS and FUS.
For common tests like EEG and MRI, technicians usually perform the scan while doctors, such as neurologists or radiologists, interpret the results. However, for tests like TCD, physicians often perform and interpret the results in real time. For other procedures like single-pulse TMS, a physician must be present if a technician is performing the task.
While these roles are established for many tests, the review found a lack of local guidelines for specific treatments like TMS and FUS. Because these procedures are complex, experts suggest that standardized national protocols are needed to ensure everything stays accurate and safe for every patient.
Common questions
Who performs and interprets common brain scans like MRI?
For tests like EEG and brain MRI, the work is typically split. Technicians perform the actual scan, while physicians, such as neurologists or radiologists, are responsible for interpreting the results to help with your diagnosis.
Do doctors have to perform every type of brain test?
Not every test requires a doctor to perform it. While some are done by technicians, others like TCD are performed and interpreted by physicians because they require real-time evaluation. For single-pulse TMS, a physician must be present if a technician is doing the work.
What are the current challenges with some brain treatments?
The review found a significant lack of local guidelines for the specific responsibilities involved in performing and interpreting TMS and FUS. Experts suggest that standardized national protocols are needed to ensure accuracy and safety for these specific procedures.
