Abstract

A setup is presented for the use of radiative antenna’s as external labeling coils for cASL at 7T. Four radiative antenna’s attached to a neck pillow filled with heavy water are used to create a B1 field in the neck. This neck pillow can be used in combination with a head coil for labeling during ASL experiments. SAR calculations show that using this setup labeling pulses for cASL can be used with a factor 5.5 longer duration than is allowed with the use of the head coil, while remaining within SAR safety guidelines.
