Report from ISMRM: Prostate imaging studies weigh diagnostic power of MRI methods

May 7, 2008 Report from ISMRM: Prostate imaging studies weigh diagnostic power of MRI methods -------------------------------------------------------------------------------- A clinical trial presented Monday demonstrated how complicated the quantification of dynamic contrast-enhanced MRI of suspected prostate cancer can be. Investigators hold great hope for DCE-MRI for this application because of the insensitivity of contrast-enhanced T2-weighted imaging and the considerable convenience of… Continue
