The effects of time varying magnetic fields can include all of the following EXCEPT:
A. Peripheral nerve stimulation
B. Magnetophosphenes
C. Acoustic damage and/or hearing loss
D. Warmth and/or increase in body temperature
Give this one a try later!
D. Warmth and/or increase in body temperature
The effects of time varying magnetic fields can include peripheral nerve
stimulation, acoustic damage/hearing loss, magnetophosphenes ("seeing

,Utilization of surface coils yields all of the following EXCEPT:
A. Increased FOV capabilty
B. Localized, smaller FOV capability
C. Increased SNR
D. Smaller slice thickness
Give this one a try later!
A. Increased FOV capabilty
Utilization of surface coils yields a more localized, smaller FOV (field of
view) capability, with increased SNR, thus providing opportunity for thinner
slices on most systems.
