Abstract: Methods, systems, computer programs, circuits and workstations are configured to generate MRI images using gradient blips for signal acquisition and reconstruction using dynamic field mapping, TE corrections and/or multischeme partial Fourier images.

Abstract: Methods, systems, computer programs, circuits and workstations are configured to carry out image processing to generate MRI images with reduced aliasing artifacts (e.g., Nyquist and/or motion-induced image artifacts) by (a) electronically reconstructing a series of images using patient image data obtained from a patient MRI image data set by iteratively cycling through different estimated values of phase gradients in at least two dimensions; and (b) electronically selecting an image from the reconstructed images as having a lowest artifact level.

Abstract: Imaging agents for magnetic resonance imaging are disclosed. Also disclosed are methods of non-invasively generating a visible image of a target tissue. In some embodiments, the discloses methods include the steps of (a) providing a contrast enhancement agent comprising a small molecule that binds to a biomolecule present in the target tissue; (b) introducing the contrast enhancement agent into the target tissue; and (c) scanning the target tissue using magnetic resonance imaging, whereby a visible image of the target tissue is non-invasively generated. Further discloses are methods for monitoring a response to a therapy, methods for selecting a therapy for a subject, methods for delineating a boundary between a diseased cell and a non-diseased cell in a tissue, and methods for assessing the degree to which a target tissue has been removed from a subject.

Abstract: Signal recovery in functional magnetic resonance imaging (fMRI) is provided by generating a single excitation pulse and exciting a target region of a subject with the generated excitation pulse. A first image is obtained using a first partial k-space frame of the target region. A compensation pulse is generated and the target region excited with the compensation pulse. A second, compensated, image is obtained subsequent to the excitation by the compensation pulse using a second partial k-space frame of the target region. The first and second images are combined to form a combined image of the target region. The first and second obtaining steps are carried out sequentially during a single quadratic excitation pulse.
