I was wondering if people could provide advice on breath-hold MRI when imaging the abdomen or chest. We are setting up a protocol with breath-holds of 20-25 seconds. It would be great if you could me know your experience and thoughts on the questions below.
What is the maximum length of a breath-hold reliably tolerated by most subjects to get high quality images?
Is it preferable to image during breath-hold after exhaling or inhaling?
