Q&A with Surabhi Sood and Viktor Vegh

      By Pinar Ozbay

Surabhi Sood

Among the Editor’s picks for May comes a paper from the Center for Advanced Imaging at the University of Queensland, Australia. In their work, entitled ‘Echo Time-Dependent Quantitative Susceptibility Mapping Contains Information on Tissue Properties’, Surabhi Sood and Viktor Vegh used a 3-compartment model to explore the echo time dependence of Quantitative Susceptibility Mapping and how this trend is varying in different regions of the brain. We conducted this Skype interview on a Tuesday evening Eastern time, while Viktor Vegh and Surabhi Sood were having their Wednesday morning coffee.

Q&A with Lotte Bertelsen and Christoffer Lausten

This month we sat down with Dr. Lotte Bertelsen, Dr. Christoffer Laustsen, and our youngest (and cutest!) MRM contributor, Lotte’s 8-month-old daughter Ellie. From their homes in Denmark, Christoffer and Lotte discussed the April Editor’s Pick: Diabetes induced renal urea transport alterations assessed with 3D hyperpolarized 13C, 15N-Urea. In this work, Lotte and Christoffer use MRI to assess renal function in diabetic and normal rats by measuring the hyperpolarized 13C-Urea gradient across the kidney.

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 Yun Jiang and Mark Griswold

Yun Jiang

BY AKSHAY CHAUDHARI

Today we sat down with Yun Jiang and Mark Griswold from Case Western Reserve University to chat a little about their recent Magnetic Resonance in Medicine manuscript, entitled, “MR fingerprinting using the quick echo splitting NMR imaging technique”. In this manuscript, the authors describe using a novel method to quantify relaxation properties of tissues with considerably lower radio frequency power deposition. Our circuitous conversation led us through some of the history of this work, through some of the specifics of the paper, and through the visions for quantitative MRI in the future. Maybe next time when you run into Mark, you may want to ask him if there are now showers in his lab space!

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 Kimberly Chan and Richard Edden

BY MATHIEU BOUDREAU

The February 2017 Editor’s Pick is from Kimberly Chan and Richard Edden, researchers at John Hopkins University and the F.M. Kirby Center for Functional Brain Imaging in Baltimore. Their paper presents a study aimed at optimizing the echo time for measuring glutathione using J-difference editing. Glutathione is the brain’s main antioxidant, and may play an important role in several psychiatric and neurological illnesses, such as schizophrenia, bipolar disorder, and Parkinson’s disease. We recently spoke with Kim and Richard about their project.

Q&A with Arcan Ertürk and Greg Metzger

BY RYAN TOPFER

Among the Editor’s picks for February comes a work from the Center for Magnetic Resonance Research at the University of Minnesota, where they’ve paired loops with dipoles for a novel hybrid transceiver. Last year, we featured the work of Alexander Raaijmakers (second author of the current work) on the fractionated dipole antenna design and we published the feature under the headline “We need antennas – not coils!” To understand this seeming about-face, we confronted Arcan and Greg over Skype about their decision to defy their collaborator’s unconventional wisdom.
