Figure 3From: Myocardial arterial spin labeling perfusion imaging with improved sensitivityMeasurements of global MBF from all subjects. (dark gray) Reference method and (light gray) accelerated method, using rate-2 SENSE. Error bars indicate physiological noise standard deviation. No significant difference was found between global MBF measured from the two techniques (p = 0.7297). The mean and standard deviation of PN across all subjects was 0.20 ± 0.08 ml/g/min from the reference method and 0.08 ± 0.05 ml/g/min for the accelerated method, corresponding to a 60% reduction. Physiological noise from the accelerated method was significantly lower than that from the reference method (p = 0.0059).Back to article page
