The most-cited scientific papers of Magnetic Resonance in Medicine

We are pleased to present the list of the five most-cited Magnetic Resonance in Medicine articles from 2014:

1. Uecker, M., Lai, P., Murphy, M. J., Virtue, P., Elad, M., Pauly, J. M., Vasanawala, S. S. and Lustig, M. (2014), ESPIRiT—an eigenvalue approach to autocalibrating parallel MRI: Where SENSE meets GRAPPA. Magn Reson Med, 71: 990–1001. doi: 10.1002/mrm.24751

Combined parallel imaging compressed sensing reconstruction of an abdomen using l1-ESPIRiT as implemented in the BART toolbox. The scan was accelerated seven-fold using variable-density Poisson-disc sampling.

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.

Q&A with Kelly McPhee and Alan Wilman

                                                                            By Atef Badji and Nikola Stikov

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.
