Table 1 Advantages and disadvantages of imaging methods
Modality
Advantages
Disadvantages
PET
Unlikely to disrupt implant placement or function Widely available Technically simple to combine with DBS (relative to fMRI) Customized radiotracers to measure binding capacity
Cost, availability and health risks of radiotracers Static data (averaged over set time interval) Poor temporal and spatial resolution (relative to fMRI) Difficult to interpret data (receptor binding vs density)
MRI
Time-locked data High temporal and spatial resolution (relative to PET) Flexible data acquisition, processing and analysis Possible analysis of ON and OFF settings
BOLD signal interpretation (temporal lag, anatomical imprecision) DBS safety considerations (lead migration, secondary lesioning) Possible deactivation of implanted impulse generators Potential DBS-related artifacts on images
