Publication number: 20140296695Abstract: Systems and methods employing spin editing techniques to improve magnetic resonance spectroscopy (MRS) and magnetic resonance spectroscopic imaging (MRSI) are discussed. Using these spin editing techniques, magnetic resonance signals of one or more non-target chemicals (chemicals whose signals are to be filtered out or suppressed) chemicals can be suppressed, so that the signal(s) of a set of target chemicals can be obtained without signals from the one or more non-target chemicals. Information about and differences between the molecular topologies of the first set of chemicals and the one or more unwanted chemicals can be used to design a sequence that suppresses the one or more unwanted chemicals while allowing acquisition of signal(s) from the first set of chemicals. These techniques can be employed to recover sharp peaks despite magnetic field inhomogeneities and susceptibility effects.Type: ApplicationFiled: April 9, 2012Publication date: October 2, 2014Applicant: UNIVERSITY OF PITTSBURGH - OF THE COMMONWEALTH SYSTEM OF HIGHER EDUCATIONInventor: Qiuhong He

Patent number: 8846098Abstract: The present invention contemplates induction of immunological tolerance thereby providing permanent allograft acceptance. This method obviates the need for a lifelong regimen of immunosuppressive agents which can increase the risk of infection, autoimmunity, and cancer.
