Journal ArticleDOI
The Alzheimer's Disease Neuroimaging Initiative (ADNI): MRI methods.
Clifford R. Jack,Matt A. Bernstein,Nick C. Fox,Paul M. Thompson,Gene E. Alexander,Danielle J Harvey,Bret J. Borowski,Paula J. Britson,Jennifer L. Whitwell,Chadwick P. Ward,Anders M. Dale,Joel P. Felmlee,Jeffrey L. Gunter,Derek L. G. Hill,Ronald J. Killiany,Norbert Schuff,Sabrina Fox-Bosetti,Chen Lin,Colin Studholme,Charles DeCarli,Gunnar Krueger,Heidi A. Ward,Gregory J. Metzger,Katherine T. Scott,Richard Philip Mallozzi,Daniel J. Blezek,Joshua Levy,Josef Phillip Debbins,Adam S. Fleisher,Marilyn S. Albert,Robert C. Green,George Bartzokis,Gary H. Glover,John P. Mugler,Michael W. Weiner +34 more
TL;DR: The approach taken in ADNI to standardization across sites and platforms of the MRI protocol, postacquisition corrections, and phantom‐based monitoring of all scanners could be used as a model for other multisite trials.
Journal ArticleDOI
Myocardial triglycerides and systolic function in humans: in vivo evaluation by localized proton spectroscopy and cardiac imaging.
Lidia S. Szczepaniak,Robert L. Dobbins,Gregory J. Metzger,Greta Sartoni-D'Ambrosia,Debbie Arbique,Wanpen Vongpatanasin,Roger H Unger,Ronald G. Victor +7 more
TL;DR: Proton magnetic resonance spectroscopy (1H MRS) is developed and validated as an in vivo tool to measure myocardial lipid content and shows evidence that it constitutes a reproducible technique for the measurement ofMyocardial triglyceride.
Journal ArticleDOI
Quantitative comparison of immunohistochemical staining measured by digital image analysis versus pathologist visual scoring.
Anthony E. Rizzardi,Arthur T. Johnson,Rachel Isaksson Vogel,Stefan E. Pambuccian,Jonathan Henriksen,Amy P.N. Skubitz,Gregory J. Metzger,Stephen C. Schmechel +7 more
TL;DR: It is demonstrated that computer-aided methods to classify image areas of interest and quantify IHC staining intensity within those areas can produce highly similar data to visual evaluation by a pathologist.
Journal ArticleDOI
Local B1+ shimming for prostate imaging with transceiver arrays at 7T based on subject-dependent transmit phase measurements.
Gregory J. Metzger,Carl Snyder,Can Akgun,Tommy Vaughan,Kamil Ugurbil,Kamil Ugurbil,Pierre-Francois Van de Moortele +6 more
TL;DR: This study demonstrates the tremendous impact of fast local B1+ phase shimming on ultrahigh magnetic field body imaging with high‐quality prostate images obtained with transceiver arrays at 7T.
Journal ArticleDOI
MRI vs. histologic measurement of breast cancer following chemotherapy: comparison with x-ray mammography and palpation.
Paul T. Weatherall,Gregory F F Evans,Gregory J. Metzger,M. Hossein Saborrian,A. Marilyn Leitch +4 more
TL;DR: MRI is an accurate method for preoperative assessment of breast cancer residua following chemotherapy and it is shown that the accuracy of MRI did not vary with the size of cancer residencyua.
