Q&A with Jun Chen and Jiang Du

BY Blake Dewey

Jun Chen

I recently had the pleasure of chatting with Drs. Jun Chen and Jiang Du about their recent MRM manuscript entitled “Measurement of Bound and Pore Water T1 Relaxation Times in Cortical Bone Using Three-Dimensional Ultrashort Echo Time Cones Sequences”. We came together over three distinct time zones, stretching from Peking, China to San Diego, California and finally to me right outside of Washington, D.C, where thanks to a strong internet connection we discussed the ups and downs of ultrashort echo time (UTE) imaging. UTE is a method for direct imaging of tissues that have short transverse relaxation times by shortening the delay between excitation and readout. For example, in this paper, the echo time for UTE imaging was only 8 μs, compared to a traditional gradient echo readout, that would have a minimum of 2-5 ms, depending on the sequence. Jun and Jiang, along with their colleagues in the U.S. and China, have been working to apply UTE sequences to explore the T1 properties of cortical bone and give clinically relevant information on components of the cortical bone structures not easily investigated with conventional radiological techniques.

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 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

                                        BY Jessica McKay

Christoffer, Lotte and Ellie, captured in midthought during our Skype interview

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!
