While these brain-imaging techniques can provide detailed images of the brain, they do have limitations. For example, PET scans require the injection of a radioactive tracer, making them invasive and potentially risky. MRI and fMRI scans require the person being scanned to remain still for an extended period, which can be difficult for some individuals. Additionally, these imaging techniques may not capture all aspects of brain function, and there may be limitations in interpreting the results.
