B)Computerized axial tomography (CAT scan)
C)Transcranial magnetic stimulation (TMS)
D)Magnetic resonance imaging (MRI)

Out of the given options, the most likely technique that the neurologist would use to examine the levels of glucose in Judith's brain is a PET scan. A PET scan can detect the metabolic activity in the brain by using a radioactive tracer that is injected into the bloodstream. The tracer binds to glucose, and the PET scanner produces images that show the distribution of the tracer in the brain. This can help the neurologist identify any areas of low glucose metabolism, which could indicate potential neurological problems. The other options, such as CAT scan or MRI, can provide structural information about the brain but do not directly measure glucose levels. TMS can be used to stimulate or inhibit specific areas of the brain but is not typically used to measure glucose levels.
