Does a SQUID magnetometer accurately detect small intestinal basic electrical rhythm compared to invasive serosal electrodes in anesthetized rabbits?
Effect estimate: r = 0.96
SQUID magnetometers can noninvasively record small intestinal basic electrical rhythm with high correlation to invasive serosal electrodes in a rabbit model.
Bradshaw et al. (1997) studied Small intestinal basic electrical rhythm / Mesenteric ischemia. Transabdominal superconducting quantum interference device (SQUID) magnetometer vs. Serosal electrodes was evaluated on Correlation of basic electrical rhythm (BER) frequency (r = 0.96). Transabdominal SQUID magnetometers noninvasively recorded small intestinal basic electrical rhythm that was highly correlated with invasive serosal electrode recordings (r = 0.96).
