"Seeing the Invisible," a lecture by Dmitry Novikov
On Monday, March 30th, Dmitry Novikov, Assistant Professor at NYU Center for Biomedical Imaging, will give a talk on breaking through the Magnetic Resonance Imaging (MRI) resolution limits to the tissue microstructure below.
MRI allows clinicians to see structures as small as one millimeter, roughly at the resolution of unaided human sight. At this scale, we can distinguish tissues—but not individual cells they’re composed of. “It’s a hard limit,” said Dr. Novikov in an interview, noting that to see such minutiae through MRI in vivo radiologists would have to scan patients with prohibitively strong magnets for extraordinarily long periods. In other words, “you cannot buy your way out of the limit”—but you may be able to think your way out.
In his lecture, titled Seeing the invisible: Tissue structure at the cellular lever with MRI, Dr. Novikov will talk about using MRI to glimpse microstructures one thousand times smaller than one millimeter. “That’s where physiology happens, that’s where pathology develops,” he noted. This relatively new and still emerging way of seeing depends on taking MRI measurements with conventional millimeter-scale resolution, and developing theoretical models to interpret the resulting data in terms of changes occurring at the scale of microns.
Dr. Novikov’s lecture is a part of the Translational Research In Progress (TRIP) Seminar series hosted by the Clinical and Translational Science Institute, an interdisciplinary partnership among New York University, the NYU Langone Medical Center, and the New York City Health and Hospitals Corporation.
Details: Monday, March 30th, 1:00pm, Smilow Research Center (map), 1st Floor Multipurpose Room.

Diffusion Imaging of Cartilage Makes JMRI Cover
The journal JMRI highlights Jose Raya's work on diffusion tensor imaging assessments of articular cartilage.
Diffusion Imaging to Assess Cartilage Makes JMRI Cover
In the June issue of the Journal of Magnetic Resonance Imaging, Dr. Raya, who develops methods for early detection of osteoarthritis, describes diffusion tensor imaging (DTI) techniques for assessment of cartilage composition and structure. In particular, he employs two DTI measures—mean diffusivity and fractional anisotropy—to evaluate two fundamental elements of cartilage tissue—proteoglycan and collagen.
The images on the cover of JMRI show longitudinal changes in DTI measurements of the knee in two patients diagnosed with osteoarthritis. The data indicate that proteoglycan content may decrease even as the structure of collagen fibers remains relatively stable. The results also demonstrate that diffusion parameters can characterize physiological changes occurring over time. Read about this and related techniques in Dr. Raya’s paper, Techniques and application of in vivo diffusion imaging of articular cartilage.

Fernando Boada Named Distinguished Investigator
The Academy of Radiology Research, has named CAI2R director Fernando Boada a Distinguished Investigator.
An advocacy based in Washington, D.C., the Academy of Radiology Research champions recognition of the role of imaging research in medical practice, and advocates dedicated funding for imaging technologies that profoundly influence healthcare.
This year the academy has honored Dr. Fernando Boada alongside 36 researchers “for their accomplishments in imaging research” and to “especially encourage those who have achieved scientific excellence while still being involved in clinical care,” according to a congratulatory letter from the Distinguished Investigator Council.
As principal investigator, Dr. Boada leads a technology research and development (TR&D) project to develop convergent MR-PET acquisition and reconstruction methods that go beyond the conventional superposition of MR and PET data.

MRM highlights XD-GRASP, developed at CAI2R
Magnetic Resonance in Medicine Journal highlights XD-GRASP in a Q&A with Dr. Li Feng and Dr. Ricardo Otazo.
In a Q&A with MRM, Li Feng, PhD, and Ricardo Otazo, PhD, discuss XD-GRASP, an imaging method that combines golden-angle radial sampling with compressed sensing to track and freeze periodic motion.
"XD" in "XD-GRASP" stands for "extra dimensional," because the technique captures more than the four dimensions we experience directly (length, width, height, and time). The method enables reconstruction of additional dimensions associated with periodic motion, such as the cycle of heartbeat or breathing.
With XD-GRASP, organs affected by periodic motion can be "frozen" after reconstruction. The heart, for instance, which not only beats but also rises and falls, pushed up and pulled down by the diaphragm, can be shown and examined as if beating in a still environment, unaffected by breathing.
Watch Dr. Feng's presentation summary of XD-GRASP:
P41 Directors Meet
CAI2R Directors attend the 2016 P41 Principal Directors' Meeting in Rockville, MD.
CAI2R Director, Fernando Boada, PhD, and CAI2R Principal Investigator Dan Sodickson, MD, PhD, convene with more than 130 scientists from over 20 other National Biomedical Technology Resource Centers and from the National Institutes of Health.
Dr. Sodickson will deliver a talk, The Changing Face of Biomedical Imaging: From Still Photography to Streaming Information, in which he will summarize the current state of imaging science, describe mounting demands for imaging to deliver greater measurable value in healthcare, and argue that the answer to those demands lies in development of rapid continuous comprehensive imaging technology. CAI2R is working toward making that vision a reality every day.
CAI2R goes to Singapore to exchange ideas with other members of the International Society of Magnetic Resonance in Medicine at the 24th annual ISMRM meeting.
CAI2R and NYU School of Medicine team comprising scientists, clinicians, technologists, and graduate students will deliver over 100 research events, including educational talks, focused discussions, oral presentations, as well as electronic and traditional posters.
The research team will present work in areas as diverse as:
- preclinical imaging
- cutting-edge diffusion methods
- RF engineering
- new frontiers in image reconstruction
- breast cancer
and many, many more. For details, see ISMRM proceedings.
MRI Points to Possible Links Between Fatty Acids and Cancer
Clinically feasible, rapid, in-vivo method details fatty acid composition in the breast.
In a study published in Radiology, CAI2R researchers investigate possible association of fatty acid fractions of adipose tissue with breast cancer.
Using a novel method, multiple gradient-echo MR spectroscopy imaging, the investigators measured fractions of monounsaturated, polyunsaturated, and saturated fatty acid in breast adipose tissue of pre- and postmenopausal women with and without breast cancer. In the paper, authors write, “Our study demonstrated that, for postmenopausal women, low monounsaturated and high saturated fatty acids may be associated with invasive ductal carcinoma, which potentially makes them useful indicators of the presence of breast cancer.”
The method is non-invasive and can be “easily used in the clinic during a routine diagnostic protocol,” according to the authors.
