- W2123743240 abstract "Results: A comparison of EMG-EDR breath locations to the reference using a 1.6-s match window (representing 20% of average breath-to-breath interval) yielded a sensitivity of 94% and a positive predictive value of 95%. Discussion: EMG-EDR performed well with minimal errors in representation of respiration activity. However, most errors were caused by one subject's occasional atrial premature beats (APBs) which inhibited MRI triggering, and thus resulted in an apparent drop in the baseline EMG levels; this caused a subsequent but temporary distortion of the EMG-EDR waveform. Data from more subjects are currently being obtained. Conclusion: On this limited data set, the ECG/EMG-derived respiration technique performs well even in the electrically noisy MRI environment. Additional algorithm logic is needed to reduce the effects of APBs. Use of this technique may allow elimination of the additional hardware of the respiratorygating belt, since ECG signals are already acquired during cardiacMRI imaging." @default.
