摘要： A computer implemented method of mapping of multiple regional center point trajectory movements of cavity walls is provided in which images are acquired and a region-of-interest is identified in each of the images. The region-of-interest is divided into a plurality of distinct regions and a regional center point for each of the regions is located in the images. For each regional center point, a center point trajectory is determined based on variances in position of the center points from each other in the images. The center point trajectory of each regional center point is decomposed into radial and circumferential components so as to isolate radial component of the center point trajectory for each regional center point in each of the images and radial motion versus time curves are displayed for each regional center point based on the determined radial component for each regional center point in each of the images.

摘要： A system and method for MR imaging includes a computer programmed to determine first and second view-ordering sequences. The first and second view-ordering sequences comprise values corresponding to respective views of first and second k-space data sets, respectively, wherein the values corresponding to a central view of each the first and second k-space data sets are positioned such that acquisition of k-space data in each central view is acquired from a first and second anatomical region, respectively, as a contrast agent passes therethrough. The positions of the values corresponding to the central views of the first and second k-space data sets within the respective sequences are different. The computer is further programmed to acquire MR data according to the first and second view-ordering sequences over a series of cardiac cycles to fill data in the first and second k-space data sets, respectively.

摘要： A system and method for optimally imaging the peripheral vasculature is disclosed which includes defining a given number of scan stations along a patient's peripheral vasculature and initially injecting a relatively small amount of contrast agent into the patient to pass a test bolus through the patient's peripheral vasculature, and thereafter tracking the test bolus through the patient and adjusting the patient on a moveable table within the MR imaging device from one scan station to a next station to determine a maximum travel time that the test bolus takes to travel through each of the given number of scan stations. Additional contrast agent is then injected into the patient to pass an exam bolus through the patient's peripheral vasculature, and using the test bolus travel time, MR data can be acquired from each scan station while it is known that the exam bolus is present in that station to optimize image resolution. Initially, central k-space data is acquired for each scan station, and if time permits, the higher spatial frequency k-space data can be acquired. Otherwise, once the central k-space data is acquired for each station, the patient table is adjusted to the scan stations that require additional data acquisition. Similarly, if there is time remaining after all MR data is acquired for a particular scan station, the patient table can be moved to a previous scan station to acquire additional data in that station before moving to a subsequent scan station to acquire the central k-space data when the exam bolus arrives in that particular scan station.

摘要： A method and apparatus is disclosed to initially screen a patient's peripheral arterial vasculature for lesions, or stenotic vessels, using MR technology, and then grading the severity of any located stenosis. The invention includes tracking the passage of a contrast agent bolus through a patient, while acquiring a series of first MR images having low resolution. This initial examination uses flow sensitive bi-polar gradient waveforms with a gradient echo imaging pulse sequence to increase the sensitivity to lesion detectability. The bi-polar gradients generate a broad distribution of velocities in a large voxel. Relevant stenoses present in a voxel will result in intra-voxel flow dephasing in voxels immediate to and distal to the stenosis. After identifying a stenosis, a second MR image, having a higher resolution than the first, is used to grade the stenosis.

摘要： The present invention includes a method and apparatus for high sensitivity whole body scanning using MR imaging. The invention includes acquiring MR data as the patient moves through the iso-center of the magnet while providing interactive control for the operator to change scan parameters and table motion and direction. The technique allows efficient whole body scanning for fast screening of abnormalities while allowing operator control during the screening process to interrupt table motion and redirect the speed and direction of the table while also allowing control over the acquisition plane, number of sections imaged, inter-section spacing, and the scan location.
