The Translational MRI Core of the BIDMC Department of Radiology provides
state-of-the-art MRI capabilities for imaging human subjects and
potentially large animals as part of research studies. The facility
operates a GE Discovery MR750 3T whole-body scanner completely dedicated to
research and can provide access to a 1.5T system.
Located in the Ansin
Building on BIDMC's East campus, the scanner is FDA cleared for clinical
use. In addition to commercial tools for clinical imaging, it has
proprietary software including pulse programming environments and
reconstruction programs and customizable software and protocols for
applications including functional and structural brain imaging, abdominal
perfusion and diffusion, muscle functional imaging and spectroscopy are
available to users.
We upgraded to the GE Discovery 3T MR750 in the winter of 2016. This new
system includes state-of-the-art hardware and software. The scanner is
equipped with an optically coupled radiofrequency system for improved
signal-to-noise ratio and with high-duty-cycle 50 mT/m gradients at 200
T/m/s slew rate.
The 3T system has high-speed echo planar imaging capabilities. Support for
fMRI acquisition and visual and auditory stimulus presentation, diffusion
tensor imaging, spectroscopy, and high quality anatomic imaging is
available. The system has specialized receiver coils for sensitive imaging
of particular anatomy. Additional customized coils can be manufactured in
our RF lab. The system also has full broadband capability for multinuclear
MRI and MRS, including (F-19, C-13, P-31, and Na-23).
To achieve high homogeneity, the 3T MR750 system is equipped with high
order resistive shimming coils as well as super-conducting shimming coils.
Additionally, the scanner will use broadband transmission to permit
multiple frequency excitation schemes, which are crucial for spectroscopy
and multi-nuclear imaging experiments. The GE MR750 system uses Multi-Drive
RF transmit, which will improve body imaging by reducing RF transmit
non-uniformity and power deposition.
The system will include a 32-channel Head array coil, 16-channel Head Neck
Spine array, 32-channel Body Array, 8-Channel Torso Array, Flex Coils in
small, medium, and large, and will have the capability to use disposable
probes for imaging the prostate, cervix, and colon. Our 3T system will
continue to have capabilities for multinuclear MRI and MRS. Through our
contract with GE, the system will be continuously updated with new
features, hardware, and capability.
Our MRI Research Suite is equipped with a Medrad (Bayer) power injector for
contrast administration and Medrad (Bayer) physiologic monitors. Subject
monitoring within the magnet includes non-invasive measures of heart rate,
blood pressure, pulse-oximetry, end tidal CO2 levels, and ECG recording.
Our facility can also provide Image Post-processing and computerized image
transfer, assistance to ensure MRI equipment safety, and can facilitate
