energy-transfer rates between a donor and an acceptor chromophore attached at …

Fundamentals of balanced steady state free precession MRI

O Bieri, K Scheffler - Journal of Magnetic Resonance Imaging, 2013 - Wiley Online Library
Balanced steady state free precession (balanced SSFP) has become increasingly popular for
research and clinical applications, offering a very high signal‐to‐noise ratio and a T 2 /T 1 ‐…

Analysis and compensation of eddy currents in balanced SSFP

O Bieri, M Markl, K Scheffler - … in Medicine: An Official Journal of …, 2005 - Wiley Online Library
Balanced steady‐state free precession (SSFP) completely compensates for all gradients
within each repetition time (TR), and is thus very sensitive to any magnetic field imperfection …

Triple echo steady‐state (TESS) relaxometry

R Heule, C Ganter, O Bieri - Magnetic Resonance in Medicine, 2014 - Wiley Online Library
Purpose Rapid imaging techniques have attracted increased interest for relaxometry, but
none are perfect: they are prone to static (B 0 ) and transmit (B 1 ) field heterogeneities, and …

Dynamics of unfolded polypeptide chains as model for the earliest steps in protein folding

F Krieger, B Fierz, O Bieri, M Drewello… - Journal of molecular …, 2003 - Elsevier
The rate of formation of intramolecular interactions in unfolded proteins determines how fast

Nasal chondrocyte-based engineered autologous cartilage tissue for repair of articular cartilage defects: an observational first-in-human trial

…, S Feliciano, F Wolf, AM Asnaghi, D Baumhoer, O Bieri… - The Lancet, 2016 - thelancet.com
Background Articular cartilage injuries have poor repair capacity, leading to progressive
joint damage, and cannot be restored predictably by either conventional treatments or …

Quantitative magnetization transfer imaging using balanced SSFP

M Gloor, K Scheffler, O Bieri - Magnetic resonance in medicine, 2008 - Wiley Online Library
It is generally accepted that signal formation in balanced steady‐state free precession (bSSFP)
is a simple function of relaxation times and flip angle only. This can be confirmed for fluids…
