HP ¹²⁹Xe spectrum obtained from rat brain <i>in vivo</i> after the administration of HP ¹²⁹Xe gas.

Abstract

<p>The spectrum was acquired from 50 averages using an RF pulse with a flip angle of 90°, and a frequency of 55.477 MHz. At least four separate peaks are discernable, the largest of which occurs at 194.7 ppm downfield from the HP ¹²⁹Xe gas peak at 0 ppm. The SNR of the largest peak is 476.</p
