    Q&A with Kawin Setsompop and Larry Wald

    BY TANGUY DUVAL

    Kawin Setsompop and Larry Wald are old friends of MRM Highlights, and their work has been prominently featured in our magazines (here, here and here). In their most recent MRM paper, they complement their simultaneous multi-slice (SMS) acquisition with an additional 3D RF-encoding for each 3mm slice (or thin slab), in order to push the resolution of diffusion imaging to 600 µm isotropic in the brain. This technique nicely solves the issue of phase corruption in multi-shot MRI acquisition.

    Q&A with Munish Chauhan and Rosalind Sadleir

                                                                                     BY Jiaen Liu

    In their paper entitled “Multishot echo-planar MREIT for fast imaging of conductivity, current density, and electric field distributions”, Drs. Munish Chauhan and Rosalind Sadleir propose an accelerated technique to image electrical conductivity based on MRI. Their goal is not only to image conductivity of biological tissues, but more ambitiously to map neural activity using this fast technique. Let’s hear their story behind the paper.

    Q&A with Sergey Cheshkov and Craig Malloy

                                                              BY ATEF BADJI

    Sergey Cheshkov

    Sergey Cheshkov received his Bachelor’s Degree in physics in Bulgaria and his PhD in physics at the University of Texas at Austin. He is currently an assistant professor in the Advanced Imaging Research Center at the University of Texas Southwestern Medical Center.

    Craig Malloy is a clinical cardiologist and the medical director of the Advanced Imaging Research Center at the University of Texas Southwestern Medical Center.

    In their paper, they used Carbon-13 NMR spectroscopy to investigate non-invasive biomarkers for brain energy metabolism and neurotransmitter production. As you can imagine, we had many questions for them.

    Q&A with Hongjiang Wei and Chunlei Liu

    By Zahra Hosseini & Phillip Ward

    Hongjiang Wei

    Recently, we had the pleasure to sit down and have a chat with Dr. Hongjiang Wei and Dr. Chunlei Liu about their editor-selected manuscript entitled “Investigating Magnetic Susceptibility of Human Knee Joint at 7 Tesla.” The conversation took a technical turn right away, when we asked the authors about their chosen technique, quantitative susceptibility mapping (or QSM). Hongjiang explained that, “quantitative susceptibility mapping is an approach to, as the name implies, extract a map of the underlying tissue susceptibility on a pixel-by-pixel basis. QSM computes the magnetic susceptibility from the phase signal of gradient recalled echoes with the assumption that phase shift is mainly due to susceptibility induced field inhomogeneity.” In simple terms, it is a map that demonstrates how tissues interact with the magnetic field of the MRI scanner.

    Q&A with Kathleen M.Ropella and Douglas C.Noll

    By Maria Eugenia Caligiuri

    Kathleen M.Ropella

    Kathleen Ropella received her Bachelor’s Degree in Biomedical Engineering at Marquette University, and her Master’s Degree at the University of Michigan, where she will defend her PhD thesis this semester (busy times ahead!).

    Douglas C. Noll did his PhD in Electrical Engineering with Al Macovski at Stanford, after being introduced by his intramural basketball pals, Dwight Nishimura, Steve Conolly, and Craig Meyer. In 1991, he started his first faculty position at the University of Pittsburgh, working on functional MRI with the first 3T magnet GE ever made. Doug later transitioned to be a professor of biomedical engineering at the University of Michigan – so he’s been in the field of MRI for about 30 years now!

    Their paper, “A Regularized, Model-Based Approach to Phase-Based Conductivity Mapping Using MRI,” was focused on two things: first, achieving accurate measurements of conductivity – which describes the ability of a tissue to conduct electric current – at tissue boundaries; and second, the possibility of using non-quadratic regularizers, thanks to advances in compressed sensing.
