Two Bi2Sr2Ca2Cu3Ox (Bi-2223) surface resonators, each of 4-cm diameter, were used in a 3T MRI. Professionally made copper resonators operate at 300 K, but each Bi-2223 resonator, operated at 77 K and demonstrated a 3.75 fold increase in SNR gain. For the same scanning time, the SNR of the images of a rat's brain and back, obtained using two small Bi-2223 surface resonators, was higher than that obtained using a single 8-cm surface resonator. © 2012 Lin et al.copper; animal experiment; article; back; brain; equipment design; female; field of view; high temperature superconducting resonator; image display; image processing; imaging; nonhuman; nuclear magnetic resonance imaging; radiation equipment; rat; signal noise ratio; Animals; Imaging, Three-Dimensional; Magnetic Resonance Imaging; Phantoms, Imaging; Rats; Signal-To-Noise Ratio; Rattusjournal article10.1371/journal.pone.0042509228800092-s2.0-84864551258WOS:000307284100114
