Facilities and Equipment

The Radiological Research Laboratory occupies more than 17,000 square feet spread over three floors of the Snyder Translational Research Building in Fontaine Research Park at the University of Virginia. Additional research space and equipment is located at the main Health System campus, including a third whole-body MRI scanner dedicated to research studies, sited immediately adjacent to University Hospital.

 

Resources of the laboratory at Snyder Translational Research Building available for whole body MRI research include:

  • Whole-body, 1.5-Tesla (Siemens Avanto) and 3-Tesla (Siemens Trio) magnetic resonance imaging (MRI) human scanners, both fully dedicated to research studies.  Scanner features include an actively-shielded super-conducting magnet (60cm clear bore with all permanent coils installed); maximum gradient strengths and slew rates of 40 mT/m [x, y] or 45 mT/m [z], and 200 T/m/s [x, y, z], respectively; digital RF system with 32 broadband, high-speed receivers; multinuclear imaging and spectroscopy; circularly-polarized body, head array, neck array, spine array, body array and flexible RF coils; wireless patient physiological monitoring and gating system (ECG, respiratory, and pulse); pulse sequence software for spin-echo, fast spin-echo, gradient-echo, magnetization-prepared gradient-echo, time-of-flight, phase contrast and contrast-enhanced MR angiography, and echo-planar and diffusion-weighted echo-planar imaging; pulse sequence and reconstruction software for parallel imaging; post-processing and analysis software for 3D imaging, spectroscopy, cardiac imaging, MR angiography, and functional brain imaging.

 

  • A 230 sq. ft. patient examination room for consent and preparation of study participants, located next to the MRI suites. Major equipment includes a handheld Koko spirometer (PDS Ferraris, Lousville, CO), a 12-lead ECG system (HP Pagewriter XLi, Hewlett Packard Co., Palo Alto, CA), and an MR compatible system for monitoring heart rate and oxygen saturation level (model 3150 MRI Patient Monitor, Invivo Research Inc., Orlando, FL).

 

  • Hyperpolarized-gas production laboratory.  Major equipment includes a 129Xe/3He gas polarization system (Model IGI.9600.Xe/He; Magnetic Imaging Technologies Inc., Durham, NC), which can routinely deliver 1 liter of 3He polarized to ~40% in 18 hours, or 0.5 liter of 129Xe polarized to 10% in approximately 1 hour, and a 3He gas polarization system using hybrid alkali spin-exchange optical pumping to deliver 3 liters of 3He polarized to 50-60% in 12 hours.

 

  • RF coils for hyperpolarized-gas imaging.  Two flexible chest 3He coils for 1.5T (1 coil suitable for small and medium-sized adults from IGC-Medical Advances, Milwaukee, WI, and 1 coil suitable for medium to large-sized adults from Clinical MR Solutions, Brook­field, WI); a rigid chest 3He coil for 1.5T (Rapid Biomedical GmbH, Würzburg, Germany); a 24-channel chest 3He coil for 1.5T (Medical Engineering & Technology Co., New York, NY); a 5-inch surface coil for 129Xe at 1.5T (Clinical MR Solutions, Brook­field, WI); a two flexible chest 129Xe coils for 1.5T (Clinical MR Solutions, Brook­field, WI); a flexible chest 129Xe coil for 3T (Clinical MR Solutions, Brook­field, WI); a 5-inch surface coil for 129Xe at 3T (Clinical MR Solutions, Brook­field, WI); and a variety of home-built birdcage coils for animal studies of 3He and 129Xe at 1.5T and 3T.

 

  • Picture archive and communication system (PACS).
