Spectris solaris mri compatible injection system

The MRI session consisted of the following scans: localizers, a high-resolution T1-weighted anatomical image, a B0 field-map image, the emotional images task, a resting-state fMRI scan, the emotional faces task, and finally, the fMRI battery task. The entire session lasted approximately 45 minutes. Participants used a mirror mounted on the head coil to view a screen mounted in the rear of the scanner bore, where visual stimuli were back projected through a wave guide in the rear wall of the scanner room. Participants also wore headphones in order to receive auditory stimuli and instructions from the researchers, as required. Physiological monitoring devices (pulse-oximeter and a respiratory belt) were attached to the participant, and these data were recorded using a standard data-recording system (AD Instruments PowerLab) in the control room. Infusions were performed using a Medrad Spectris Solaris MRI compatible injection system, which was also controlled using a remote panel in the control room.

During the MRI session, a series of anatomical and functional brain scans were performed. During the functional tasks, a mirror mounted on the head coil was used to view a screen at the rear of the scanner bore, onto which the stimuli were projected. To respond to the tasks, the participants were equipped with a custom-made, 5-button, MRI-compatible response box. In addition, a pulse oximeter and a respiratory belt were used to monitor physiological data by means of a standard data-recording system (AD Instruments PowerLab) in the control room. Kisspeptin and placebo infusions were administered via a Medrad Spectris Solaris MRI-compatible injection system controlled from a remote panel in the control room.
