Abstract
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.
Claims15
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.
A system, comprising:
- a magnetic resonance (MR) scanner;
- at least one computing device;
- and
- at least one application executable in the at least one computing device, the at least one application comprising:
- logic that performs
- a) selection of an abdominal region of a subject having one or more visceral organs of interest for T1 mapping;
- b) detection of whether heart associated motion is present in the selected region;
- c) if no motion is detected, artificially triggering T1 mapping of the selected region;
- d) if heart associated motion is detected, also determining whether either high heart rate or irregular heart beat is present;
- e) if neither high heart rate, nor irregular heart beat is present, then triggering T1 mapping of the selected region by heart beat;
- f) if either high heart rate or irregular heart beat are present, then artificially triggering T1 mapping of the selected region;
- and
- g) acquisition of T1 maps of the one or more visceral organs interest in the selected abdominal region using the MR scanner.
