How long should breath-holds be for MRI of the chest and abdomen?

Hi everyone,

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?

My personal experience is that anything above 10s is asking too much from the patient specially if they have some sort of pathology.

Imaging after exhaling seems to allow the most consistency between different Breath-holds.
