Purdue Magnetic Resonance Imaging Facility

The Purdue MRI Facility (West Lafayette, IN) has in place and operational a 3T General Electric (Milwaukee, WI) Signa HDx imager with EXCITE. This system is located in the Purdue Research Park, a five-minute distance from the main campus of Purdue University, in a facility shared with InnerVision West, a local out-patient imaging center. The Purdue MRI Facility is research-available over 50 hours per week, at a rate of $400 per hour, with an additional hour scheduled for set-up and tear-down for each scheduled scanning hour. The 3T MRI is equipped with proton spectroscopy for MRS and a real-time acquisition system for use with echo-planar fMRI. All data acquired on the MRI may be directly transferred via high-speed internet connection to the PI's computers at Purdue University for subsequent processing. Backups of data may be generated on-site using DVD-R or CD-R media.

For fMRI purposes, the Purdue MRI Facility is equipped with a NordicNeuroLab Audio/Visual system (electrostatic headphones plus 800x600 LCD goggles) for high-quality auditory and visual stimulation, and bimanual fiber optic button pads (Current Designs, Inc.) for recording subject responses. The Facility also provides an Audio/Visual computer (dual boot between Windows XP and Linux) with which stimuli may be presented and responses recorded (e.g., via e-Prime). In addition, the Facility provides a trigger box for stimulus synchronization and the ability to record physiologic data (respiration and heart rate) for post-acquisition use.


The Purdue MRI Facility also houses a small animal MRI scanner in the Bindley Bioscience Center located in Purdue's Discovery Park (located just south of State St. along S. Martin Jischke Drive) - a new small animal 7.0 Tesla Bruker Biospec 70/30 USR 305 mm bore horizontal axis with two actively shielded gradient systems, multiple body and surface RF coils, and Paravision and Topspin software, capable of in vivo rabbit, rat, and mouse studies at high spatial resolution.

{taken from:} 7.0 Tesla Bruker (Billerica, MA) Biospec 70/30 USR 305 mm bore horizontal axis, actively shielded superconducting magnet operating at a proton frequency of 300MHz. This instrument was installed in March of 2014 and is located in the Bindley Bioscience Center in Discovery Park on the main campus of Purdue University. The 7.0T imager is available at all times during the week for trained personnel. The imager is equipped with two actively shielded gradient systems (BGA-20S and BGA-12S) with built in RT shims and a high power gradient amplifier providing strengths up to 660 mT/m. A console with a dual channel RF transmitter and dual receiver system, operated by a Linux workstation, with Paravision and Topspin software, is capable of multinuclear spectroscopy and imaging. The imager is equipped with multiple volume and surface RF coils, basic life monitoring and temperature control systems, and animal cradles. The 7.0T imager will be used for rabbit, rat, and mouse studies that require high spatial resolution.
