Journal ArticleDOI
OsiriX: An Open-Source Software for Navigating in Multidimensional DICOM Images
TL;DR: OsiriX was designed for display and interpretation of large sets of multidimensional and multimodality images such as combined PET-CT studies and ensures that all new developments in image processing that could emerge from other academic institutions using these libraries can be directly ported to the OsiriX program.

TL;DR: A strategic five-phase roadmap to foster the clinical validation of biomarkers in Alzheimer's disease, adapted from the approach for cancer biomarkers is developed.
Journal ArticleDOI
Design and performance evaluation of a whole-body Ingenuity TF PET-MRI system
Habib Zaidi,Navdeep Ojha,Michael A. Morich,Jerome J. Griesmer,Zhiqiang Hu,Piotr Maniawski,Osman Ratib,David Izquierdo-Garcia,Zahi A. Fayad,Ling Shao +9 more
TL;DR: The results were comparable to PET-CT systems demonstrating that the effect of design modifications required on the PET system to remove the harmful effect of the magnetic field on the PMTs was negligible, and it is conceived that advantages of hybrid PET-MRI will become more evident in the near future.
Journal ArticleDOI
13N ammonia myocardial imaging at rest and with exercise in normal volunteers. Quantification of absolute myocardial perfusion with dynamic positron emission tomography.
Janine Krivokapich,G. T. Smith,Sung-Cheng Huang,Edward J. Hoffman,Osman Ratib,Michael E. Phelps,Heinrich R. Schelbert +6 more
TL;DR: The noninvasive technique of PET imaging with 13N ammonia shows promise for future applications in determining absolute flows in patients with coronary artery disease.
Journal Article
Positron Tomography with Deoxyglucose for Estimating Local Myocardial Glucose Metabolism
Osman Ratib,Michael E. Phelps,Sung-Cheng Huang,Eberhard Henze,Carl Selin,Heinrich R. Schelbert +5 more
TL;DR: Improvements of PCT resolution are required to improve the accuracy of the estimates of the rate constant and the MMRGlc, and a constant representing the combination of transport and phosphorylation was accurately determined and yielded measured values of the myocardial metabolic rate for glucose.
