  • Adaptive keyhole compression for dynamic contrast-enhanced MRI
    Patent number: 9429636
    Abstract: A magnetic resonance imaging system (3) includes a sequence control unit (18), a sampling unit (26), and a control unit (24). The sequence control unit (18) controls a magnetic resonance scanner (4) to acquire compressed magnetic resonance data from an imaged region of a subject. The sampling unit (26) determines a change in a concentration of a contrast agent present in the image region of the subject based on magnetic resonance signals received by a radio frequency receiver. The control unit (24) adjusts a degree of compression of the acquired magnetic resonance data based on the determination made by the sampling unit (26).

  • Systems and methods for imaging changes in tissue
    Patent number: 9289140
    Abstract: The present invention provides systems and methods for monitoring tissue regions. In particular, the present invention provides systems and methods for detecting changes in tissue regions over a period of time. In some embodiments, the systems and methods of the present invention are used to evaluate the effectiveness of a particular treatment of a tissue region. In some embodiments, the systems and methods of the present invention provide a parametric response map approach for detecting and analyzing changes in tissue regions over a period of time to detect and monitor disease or tissue health and to monitor the impact of therapeutic interventions.

  • Noninvasive method to determine fat content of tissues using MRI
    Publication number: 20050215882
    Abstract: The present invention relates to systems and methods for generating high resolution MR images of the fractional amount or percentage of fat content in an imaged object. In particular, the present invention relates to systems and methods for obtaining high resolution MR images of fat content with reduced NMR relaxation effects. Moreover, the present invention relates to systems and methods for obtaining high resolution MR images of fat content with reduced fat-percentage ambiguity. Furthermore, the present invention relates to systems and methods for diagnostic, and prognostic imaging where knowledge of fat content within tissues, organs, and lesions is beneficial to improve diagnostic accuracy, aid in risk assessment of future disease, and aid in assessment of therapeutic intervention.
