Among the Editor’s picks for May comes a paper from the department of Physics at the University of Alberta in Edmonton, Canada. In their work entitled ‘Transverse relaxation and flip angle mapping: Evaluation of simultaneous and independent methods using multiple spin echoes’, Kelly McPhee and Alan Wilman evaluated transverse relaxation (T2) and flip angle maps derived from Bloch simulations and Extended Phase Graphs (EPG). We conducted this interview with Kelly on a beautiful Sunday afternoon at the Honolulu convention center during the annual ISMRM meeting.

Q&A with Davide Piccini and Matthias Stuber


                                                                     By Agâh Karakuzu

In this April’s Editor’s pick, pieces from previous Highlights features are coming together. About a year ago Dr. Davide Piccini foreshadowed their collaborative study with NYU to incorporate XD-GRASP into their work on free-breathing motion correction. Seems like it was a productive year for Davide, as he not only delivered on his research promise, but also became a father. The Highlights team extends their sincerest congratulations to the Piccini family! We spoke to Davide and senior author, Prof. Matthias Stuber from the University of Lausanne, about their recent paper on Four Dimensional Respiratory Motion-Resolved Coronary MR Angiography. 

Q&A with Nara Higano, Andrew Hahn and Jason Woods



NICU magnet – Jason Woods and Nara Higano

This month we are featuring a collaboration between the Cincinnati Children’s Hospital Medical Center, the Washington University in St. Louis and the University of Wisconsin – Madison. Nara Higano, Andrew Hahn, Jason Woods and colleagues used a converted orthopedic MRI scanner to measure tidal volume (the difference between lung volume in the inspired and expired state) in neonates.  As you can imagine, we are talking small volumes here (on the order of tens of milliliters), and achieving this with 3D radial ultrashort echo-time (UTE) MRI is no small engineering feat that owes a great deal to some of the early MR projection reconstruction techniques.

Q&A with Melissa Terpstra and Gulin Öz


In this edition of Highlights Q&A, we were treated to a virtual interview with Dr. Melissa Terpstra and Dr. Gülin Öz, whose work at the University of Minnesota Center for Magnetic Resonance Research (CMRR) has provided unique insight into the reproducibility of spectroscopic data. Our conversation revolved around their investigative efforts to understand how field strength influences consistent neurochemical quantification. By comparing short-echo semi-LASER data from 3T and 7T acquisitions, they managed to arrive at some interesting conclusions that bear direct relevance to other studies, and also underscore the necessity of quality assurance for purposes of clinical translation.

Q&A with Dongmei Wu and E. Mark Haacke


In this Highlights Q&A we chat with Dongmei Wu about her technique to reverse phase history through gradient moment nulling, and senior author E. Mark Haacke takes a moment to tell us the history behind “The Green Book”.

Q&A with Jelle Veraart, Els Fieremans, and Dmitry Novikov


One of the editor’s picks for the month of July is a paper entitled “Gibbs Ringing in Diffusion MRI”. Recently, we talked with Drs. Jelle Veraart, Els Fieremans, and Dmitry Novikov to learn more about how they use regularization functions to mitigate artifacts induced by Gibbs ringing in diffusion MRI.

Q&A with Eric Pierre and Mark Griswold


Magnetic Resonance Fingerprinting (MRF) was all the rage at the annual ISMRM meeting in Singapore, culminating with the Young Investigator Award (YIA) given to Dan Ma for her work on MRF music. Eric Pierre’s paper that we are highlighting in June provides the reconstruction framework that led to the YIA. The Highlights team interviewed Eric and senior author Mark Griswold.

Q&A with Yunkou Wu and Dean Sherry


For the first Editor’s pick of June, Dr. Yunkou Wu and Prof. Dean Sherry from the University of Texas Southwestern Medical Center have developed a novel paraCEST agent seeking to push the envelope of robust pH quantification in-vivo. We spoke with them over Skype to discuss this new technique and its implications for the CEST field, as well as the broader MR community.

Q&A with Sebastiano Barbieri and Harriet Thoeny


We sat down with Dr. Sebastiano Barbieri and Dr. Harriet Thoeny from Inselspital University Hospital to discuss their paper, “Impact of the Calculation Algorithm on Biexponential Fitting of Diffusion-Weighted MRI in Upper Abdominal Organs”. Sebastiano, who completed his Ph.D. at Jacobs University and the Fraunhofer Institute for Medical Image Computing in Germany, has a background in math and image processing. Harriet is a radiologist dedicated to urogenital and head and neck radiology with main research interest in functional MRI, and special focus on diffusion-weighted MRI. In their paper, they assess six different algorithms for fitting a biexponential IntraVoxel Incoherent Motion (IVIM) model.

Q&A with Hojin Ha


Hojin Ha is currently a postdoctoral researcher at Linköping University in Sweden, working on developing 4D phase-contrast MRI (PC-MRI) techniques. His paper entitled “Multi-VENC Acquisition of Four-Dimensional Phase-Contrast MRI to Improve Precision of Velocity Field Measurement” was selected as an Editor’s pick for the month of May. The paper demonstrates a technique for improving the velocity signal of 4D PC-MRI, and the use of a 3D printed phantom for modeling the aortic valve. We caught up with Hojin to discuss his work and life in Sweden.
