Pseudo-continuous arterial spin labeling (PCASL) is a
quantitative CBF-fMRI pulse sequence. We investigate
feasibility of simultaneous electroencephalography (EEG)
and PCASL multi-modal measurement. Specific absorption
rate (SAR) of PCASL, may increase the temperatures of
EEG electrodes and thus have potential safety risks. To
evaluate the feasibility and safety we performed
real-time measurements of EEG electrode temperatures
during concurrent EEG&PCASL (acquired with standard
imaging hardware) at 3 Tesla. The results showed that
the electrode temperature after a long PCASL scan will
reach about 34C - well below the safety limit (41C).
Results show feasibility of multi-modal EEG&PCASL
experiments.
