    Nathan A Pack
    Department of Bioengineering, University of Utah, Salt Lake City, Salt Lake County, Utah, USA
    J Cardiovasc Magn Reson 10:52. 2008
    ..We investigated these questions with a model-independent analysis method that uses iterative minimization and a temporal smoothness regularizer. Perfusion estimates using this method were compared to results from dynamic 13N-ammonia PET...

    Edward V R DiBella
    UCAIR, Department of Radiology, University of Utah, Salt Lake City, UT, USA
    Int J Cardiovasc Imaging 28:1435-44. 2012
    ..Fixed dose regadenoson and weight adjusted adenosine produce similar measures of MPR in patients with a wide range of body sizes. Regadenoson is a potentially useful vasodilator for stress MRI studies...

    Nathan A Pack
    Department of Bioengineering, University of Utah, Salt Lake City, Utah, USA
    Magn Reson Med 64:125-37. 2010
    ..When more than just the first pass of data was analyzed, perfusion estimates from two-compartment modeling and model-independent analysis did not change significantly, unlike results from Fermi function modeling...

    J Cardiovasc Magn Reson 12:45. 2010
    ..This work seeks to evaluate the performance of a method that uses a radial k-space perfusion sequence and multiple saturation recovery times (SRT) to quantify myocardial perfusion with cardiovascular magnetic resonance (CMR)...
