Robert C. Long, Jr. Ph.D. of the Department of Radiology manages the 4.7T small animal imaging core facility. The facility is located in Room B120 of the Woodruff Memorial Research building and provides access for Emory researchers to imaging and spectroscopy. The lab is conveniently located adjacent to the animal facility in the WMB. A workspace for animal preparation is provided in the magnet room. The workhorse of the core is a state-of-the-art Varian Inova 4.7T/200MHz 33 cm horizontal imaging/spectroscopy system. Two gradient sets are available with different gradient strengths 10 G/cm large bore (22.2 cm i.d.) and 25 G/cm small bore (11.7 cm i.d.). These allow studies in vitro samples as well as in vivo experiments for animals. Animals as small as mice and as large a rhesus monkeys can be studied. Many NMR sequences are available including Spin-echo (SE), Gradient-echo (GRE), Fast Spin Echo (FSE), 3D-Gradient Echo (3D-GRE) Diffusion Weighted Spin Echo (DW-SE) as well as Echo-Planar (EPI). Localized spectroscopy using the PRESS and STEAM are also available. Multinuclear capability allows investigations to be carried out on 13C, 31P, 19F, and 23Na with specialty coils. Cardiac-gated studies and cine MRI can be done on mice and rats.
