1. Although his ability to speak is otherwise normal, a Use functional magnetic
patient suffering from a stroke is having difficulty resonance imaging (fMRI)
naming common objects, such as tools. In order to to compare the activity
determine which region of the brain is functioning of the brains of the pa-
abnormally, which non-invasive technique would be tient and normal volun-
the most useful approach for his doctor to use for lo- teers when they name
calizing the impaired functional region and providing tools
a diagnosis?
During neurosurgery on the patient, electrically stim-
ulate his entire brain until tools are named
Do a computed tomography (CT) scan on the brain to
look for skull injuries
During neurosurgery on the patient, perform an ab-
lation procedure to remove a portion of the temporal
lobe
Use functional magnetic resonance imaging (fMRI) to
compare the activity of the brains of the patient and
normal volunteers when they name tools

resolution so it is difficult to identify when signals are
happening
Compared to other techniques, it is very invasive and
risky for participants
Compared to other techniques, it is very expensive
and costly to obtain and run
5. Ken is volunteering to be a subject in medical re- electrocorticogram
search, but he is prone to infection and would like (ECoG)
to avoid any highly invasive procedures. Which of the
following methods is the MOST invasive and risky for
Ken?
electroencephalogram (EEG)
magnetoencephalogram (MEG)
electrocorticogram (ECoG)
transcranial magnetic stimulation (TMS)
diffusion tensor imaging (DTI)
6. Michael fractured his arm and had to have screws Computed Tomography
inserted while it heals. Assume the screws are made (CT) Scan
of a magnetic metal and could be pulled out by ex-
posure to a strong magnet. Which imaging technique
would NOT involve exposure to a strong magnet and
therefore would be the SAFEST for Michael?
