Classification: CPC G  A | IPC A  G

Claim 11:
12. A magnetic resonance imaging (MRI) system comprising:
a magnet system configured to generate a polarizing magnetic field about at least a portion of a subject;
a magnetic gradient system including a plurality of gradient coils configured to apply at least one gradient field to the polarizing magnetic field;
a radio frequency (RF) system configured to apply an excitation field to the subject and to receive MR data from the subject using a coil array; and
a computer system programmed to:
acquire, after administration of a contrast agent, a set of MR data from the subject using a three-dimensional volumetric pulse sequence having a temporal resolution and a spatial resolution configured to facilitate measurement of volumetric and motility parameters, wherein acquiring a set of MR data from the subject using a three-dimensional volumetric pulse sequence comprises:
acquiring a first set of MR data from the subject using the three-dimensional volumetric pulse sequence at a first time point after administration of the contrast agent;
acquiring a second set of MR data from the subject using the three-dimensional volumetric pulse sequence at a second time point after administration of the contrast agent; and
acquiring a third set of MR data from the subject using the three-dimensional volumetric pulse sequence at a third time point after administration of the contrast agent;

reconstruct a set of images using the set of MR data;
segment each image in the set of images to isolate a region of interest in a gastrointestinal tract of the subject;
determine at least one volumetric or motility parameter based on the set of segmented images; and
generate a report indicating the at least one volumetric or motility parameter.
