This test involves the uses of special dyes which is made up of radioactive tracers, they are either injected or inhaled by patient depending on the organ which the test is to be carried out on.
So the next best technique Veda could use as she doesn't have access to an fMRI machine is the Positron Emission Tomography (PET).
Using this technique, the PET scanner can trace the special dyes contain radioactive tracer as they are more concentrated on areas or part of the organs with high chemical activities, this could help her get information about brain activity during the card task.
