SYSTEMS AND METHODS FOR GATED MAPPING OF T1 VALUES IN ABDOMINAL VISCERAL ORGANS

摘要

The present disclosure provides systems and methods for universal mapping of T1 in abdominal organs using cardiac gating. A region of interest is selected for mapping or imaging. A determination is made whether any one or more of heart associated motion, high heart rate and irregular heart beat are detected in the region of interest. A multi-pathway gating of T1 maps is then employed providing a universal method of T1 mapping of moving as well as non-moving visceral organs.

主权项

1. A method for performing spin-lattice (T1) mapping of visceral organs, comprising:
a) positioning a subject in association with a magnetic resonance (MR) scanner; b) selecting an abdominal region of the subject having one or more visceral organs of interest for T1 mapping; c) detecting whether heart associated motion is present in the selected region; d) if no motion is detected, artificially triggering T1 mapping of the selected region; e) if heart associated motion is detected, also determining whether either high heart rate or irregular heart beat is present; f) if neither high heart rate, nor irregular heart beat is present, then triggering T1 mapping of the selected region by heart beat; g) if either high heart rate or irregular heart beat are present, then artificially triggering T1 mapping of the selected region; and h) acquiring T1 maps of the one or more visceral organs interest in the selected abdominal region using the MR scanner.
