Journal ArticleDOI
Parahydrogen-Based Hyperpolarization for Biomedicine
Jan-Bernd Hövener,Andrey N. Pravdivtsev,Bryce E. Kidd,C. Russell Bowers,Stefan Glöggler,Kirill V. Kovtunov,Markus Plaumann,Rachel Katz-Brull,K. Buckenmaier,Alexej Jerschow,Francesca Reineri,Thomas Theis,Roman V. Shchepin,Shawn Wagner,Pratip K. Bhattacharya,Niki M. Zacharias,Eduard Y. Chekmenev,Eduard Y. Chekmenev +17 more
TL;DR: Considerable progress has been made in the past decade in the area of pH2 -based hyperpolarization techniques for biomedical applications, covering the areas of spin physics, catalysis, instrumentation, preparation of the contrast agents, and applications.
Journal ArticleDOI
Level anti-crossings are a key factor for understanding para-hydrogen-induced hyperpolarization in SABRE experiments.
Andrey N. Pravdivtsev,Alexandra V. Yurkovskaya,Hans-Martin Vieth,Konstantin L. Ivanov,Robert Kaptein,Robert Kaptein +5 more
TL;DR: An analysis based on level anti-crossings (LACs) provides a complete understanding of the SABRE effect, and the field-dependence of both net and anti-phase polarization is measured for several ligands, which can be reproduced by the theory.
Journal ArticleDOI
The role of level anti-crossings in nuclear spin hyperpolarization
Konstantin L. Ivanov,Konstantin L. Ivanov,Andrey N. Pravdivtsev,Andrey N. Pravdivtsev,Alexandra V. Yurkovskaya,Alexandra V. Yurkovskaya,Hans-Martin Vieth,Robert Kaptein +7 more
TL;DR: Here, an analysis of polarization transfer in terms of LACs in the rotating frame is very useful to predict which spin orders are transferred depending on the strength and frequency of the B1 field.
Journal ArticleDOI
RF-SABRE: A Way to Continuous Spin Hyperpolarization at High Magnetic Fields
Andrey N. Pravdivtsev,Andrey N. Pravdivtsev,Alexandra V. Yurkovskaya,Alexandra V. Yurkovskaya,Hans-Martin Vieth,Konstantin L. Ivanov,Konstantin L. Ivanov +6 more
TL;DR: It is demonstrated that LAC conditions can also be fulfilled at high fields under the action of a RF field and can serve as a new sensitive tool for probing transient complexes.
Journal ArticleDOI
A simple analytical model for signal amplification by reversible exchange (SABRE) process
Danila A. Barskiy,Andrey N. Pravdivtsev,Konstantin L. Ivanov,Kirill V. Kovtunov,Igor V. Koptyug +4 more
TL;DR: An analytical model for the description of the signal amplification by reversible exchange (SABRE) process is demonstrated, which provides rationale for deciding which system parameters have to be optimized in order to achieve higher signal enhancement for a substrate of interest in SABRE experiments.
