  • ELIMINATION OF CONTRAST AGENT CONCENTRATION DEPENDENCY IN MRI
    Publication number: 20090196830
    Abstract: The present invention relates to a method for MRI imaging to obtain information about a local physiochemical parameter after administration to a patient of a contrast agent comprising at least one non-responsive contrast enhancing entity that does not occur naturally in a human body and at least one responsive contrast enhancing entity attached to or mixed with the non-responsive contrast enhancing entity. By using such non-responsive contrast enhancing entities, a value for the physicochemical parameter can be obtained by acquiring only three images through which the method according to the present invention will be easier to apply in clinical routine since it will be faster and less sensitive to motion or flow artefacts.

  • Distinguishing Bound and Unbound Contrast Agents Using Magnetic Resonance
    Publication number: 20080258726
    Abstract: Magnetic resonance monitoring of a target (30) uses the detected magnetic resonance to determine movement such as diffusion of contrast agent relative to the object, and uses the movement to discriminate (50, 60) a part of the contrast agent which is bound to the target, from the rest of the contrast agent. The need for clearing agents can be avoided or reduced, and hence imaging is instantaneous. A “stationary spin map” of the object can be formed by comparing the movements in the different directions, and determining if the differences between them are less than a given threshold. Determining isotropic movement in this way for a number of locations on the object allows the map to be generated.

  • Mri Involving Contrast Agent With Time Modulated Contrast Enhancement
    Publication number: 20080200799
    Abstract: The present invention provides a method MRI imaging. By applying a time modulation to the contrast enhancement of an MRI contrast agent, the method according to the invention leads to images with improved signal-to-noise ratio in the contrast-enhanced areas, strongly suppressed unwanted signal in the unenhanced areas, and reduced artefacts, such as motion artefacts.

  • Magnetic resonance imaging method with sub-sampling
    Patent number: 6377045
    Abstract: A spectroscopic magnetic resonance imaging method involves sub-sampling in the k space. For example, the SENSE technique is applied in spectroscopic MR imaging. Such sub-sampling is also applied in three-dimensional MR imaging.
