Journal ArticleDOI
Cardiac SSFP imaging at 3 Tesla
TL;DR: An optimized sequence protocol for cardiac SSFP imaging at 3.0T is derived, taking into account several partly adverse effects at higher field, such as increased field inhomogeneities, longer T1, and power deposition limitations.
Journal ArticleDOI
Nuclear Overhauser enhancement (NOE) imaging in the human brain at 7T.
Craig K. Jones,Alan J. Huang,Jiadi Xu,Jiadi Xu,Richard A.E. Edden,Richard A.E. Edden,Michael Schär,Jun Hua,Jun Hua,Nikita Oskolkov,Nikita Oskolkov,Domenico Zacà,Jinyuan Zhou,Jinyuan Zhou,Michael T. McMahon,Michael T. McMahon,Jay J. Pillai,Peter C.M. van Zijl,Peter C.M. van Zijl +18 more
TL;DR: First data on a tumor patient show reduction in both relayed NOE and CEST amid proton signals leading to an increase in magnetization transfer ratio asymmetry, providing insight into previously reported amide proton transfer (APT) effects in tumors.
Journal ArticleDOI
Magnetic Resonance Imaging Overestimates Ferumoxide-Labeled Stem Cell Survival After Transplantation in the Heart
John Terrovitis,Matthias Stuber,Amr Youssef,Steve Preece,Michelle K. Leppo,Eddy Kizana,Michael Schär,Gary Gerstenblith,Robert G. Weiss,Eduardo Marbán,M. Roselle Abraham +10 more
TL;DR: The persistence of significant iron-dependent MRI signal derived from ferumoxides-containing macrophages despite few or no viable stem cells 3 weeks after transplantation indicates that MRI of ferumoxide-labeled cells does not reliably report long-term stem cell engraftment in the heart.
Journal ArticleDOI
Positive contrast visualization of iron oxide-labeled stem cells using inversion-recovery with ON-resonant water suppression (IRON)
Matthias Stuber,Wesley D. Gilson,Michael Schär,Michael Schär,Dorota A. Kedziorek,Lawrence V. Hofmann,Saurabh Shah,Evert-Jan Vonken,Jeff W.M. Bulte,Dara L. Kraitchman +9 more
TL;DR: The first successful use of IRON to produce positive contrast in areas of metallic spheres and SPIO‐labeled stem cells in vitro and in vivo is presented.
Journal ArticleDOI
Intracranial arterial wall imaging using three-dimensional high isotropic resolution black blood MRI at 3.0 Tesla.
Ye Qiao,David A. Steinman,Qin Qin,Qin Qin,Maryam Etesami,Michael Schär,Michael Schär,Brad C. Astor,Brad C. Astor,Bruce A. Wasserman +9 more
TL;DR: A high isotropic‐resolution sequence is developed to evaluate intracranial vessels at 3.0 Tesla (T) to develop a high-resolution database of blood vessel constellations.
