MRI about

MRI is a noninvasive imaging tool for physiological, pre-clinical, and clinical research. The service includes consulting and designing MRI protocols for the researcher's need, implementing of advanced protocols, and assistance in image analysis.

The center comprises a 3T whole Body (wide bore) MRI scanner (Siemens TIM TRIO) used mainly for imaging experiments on Human subjects and for developing and testing new MRI methods. The system has 32 channels and is equipped with unique coils for whole body 1H imaging and spectroscopy (including 32 channel head coil, 12 channels head matrix coils, a neck matrix coil, a spine matrix coil, 4 and 7 channels breast matrix coils, a 6 channels body matrix coil, a CP extremity coil, a Tx/Rx CP head coil, a double tuned head coil for proton imaging and 1H decoupled 31P spectroscopy, and a double tuned flex coil for proton imaging 1H decoupled 23Na spectroscopy). Among the applications that are included on the system are BOLD imaging, diffusion and perfusion imaging, MR angiography, flow measurements, spectroscopy, neuro-imaging, breast imaging, whole-body imaging, and abdominal imaging.

Currently, the system is being used primarily by researchers from the Department of Neurobiology for functional brain imaging (fMRI), an advanced imaging technique that enables to map brain activity , and for developing and testing new methods and protocols for MRI and MRS with the IDEA platform. The facility includes the following MR compatible devices that can be used for fMRI studies: A visual system for presenting high-quality visual stimuli in the MRI, An Audio system including headphones and a dual channel MRI microphone system, A 32-channels MR compatible EEG, Response devices, An Eye tracking system, a software for real time fMRI analysis that allows neuro- feedback studies, and a system for physiological data monitoring and acquisition during MRI (including pulse, respiration, EMG, EOG, EEG, and skin conductivity). Additionally the facility includes an MRI simulator – a non magnetic replication of the MR environment to familiarize and train the participants with the research setting.
