Plenary Description

The advancement of cell and gene therapies has transformed medicine in recent years providing potentially curative treatments for several complex diseases. At variance to small molecule and protein-based therapeutics, these new treatment modalities unlock hitherto unseen potential but present with several additional challenges after administration. These include their in vivo distribution, the challenge of determining their in vivo activities, and in the case of cell-based therapeutics their potential to expand, to relocate to unintended tissues, and uncertainties relating to their in vivo fate. I will use illustrative examples to give an overview of how molecular imaging has been exploited to address these challenges, what has been achieved, and what we can expect in the near- to medium-term future.

Plenary Description

In recent decades, computed tomography (CT) has become an indispensable tool in modern medicine, revolutionizing how we diagnose and treat a vast array of medical conditions. CT ability to provide detailed cross-sectional images of the human body has profoundly enhanced the precision, speed, and reliability of medical diagnostics. Today, approximately 375 million CT scans are performed annually worldwide—a number that continues to rise by 3–4% each year. This exponential growth underscores the critical role of CT technology in patient care, from routine diagnostics to life-saving interventions. The global computed tomography (CT) scanners market size is projected to grow from $7.5 billion in 2024 to $12 billion by 2032, at an annual growth of over 6%.

Spectral Dual Energy and Spectral Photon-Counting Computed Tomography (SPCCT) represent the latest frontier in this transformative journey. Building on the foundational principles of CT, Spectral CT offer unprecedented capabilities by harnessing photon counting detectors to differentiate X-ray photons by their energy levels. These innovation enable detailed tissue characterization, precise imaging of contrast agents, and the potential for reducing radiation dose, marking a paradigm shift in diagnostic imaging.

Speaker Biography

Salim Aymeric Si-Mohamed, MD, PhD, is a full professor in medical imaging at the University Claude Bernard Lyon 1 and head of the Cardiovascular and Thoracic Imaging Department at Louis Pradel Hospital in Lyon. Specializing in diagnostic and interventional imaging for cardiovascular and thoracic diseases, he primarily works with cutting-edge CT technology. Dr. Si-Mohamed’s experimental research focuses on the development of spectral CT technology, including spectral photon-counting CT and dual-energy CT systems, integrated with novel contrast agents for cardiovascular and thoracic applications. He earned his MD in 2016 and completed his PhD in 2020, with his doctoral research dedicated to the cardiovascular applications of spectral photon-counting CT technology. His groundbreaking work demonstrated the feasibility of color K-edge imaging for cardiovascular imaging, particularly in studying atherosclerosis.

He has authored over 150 publications in leading international journals and conferences, focusing on both experimental and clinical spectral CT imaging. Dr. Si-Mohamed teaches the principles, techniques, and applications of spectral CT, mentoring MSc and PhD students. He is also the holder of an international patent. Recently he was awarded an ERC Starting Grant for the KOLOR SPCCT Imaging Project and an ERC Proof-of-concept Grant for the developement of a KOLOR Viewer, aimed at advancing comprehensive, one-breath-hold imaging of lung diseases using color K-edge imaging and dedicated contrast agents.

Michael Tweedle, PhD

Fri, September 11th: 9:00 AM - 10:00 AM

Michael Tweedle, PhD
Emeritus Stefanie Spielman Professor of Cancer Imaging and Professor of Radiology
The Ohio State University College of Medicine and James Comprehensive Cancer Center

Talk Title: “Discovery to Precision: The Next Era of Imaging Agents

Followed by Moderated Expert Panel

Moderator: Jim Delikatny – University of Pennsylvania

Joining Michael Tweedle on the panel:

  • Janet Morrow – University of Buffalo
  • Eric Gale – MGH & Harvard Medical School
  • Adam Shuhendler – University of Ottawa 
Plenary Description

I will highlight major historical developments in the field of human in vivo imaging agents used in X Ray, Nuclear, MRI, Ultrasound and Optical imaging.  It will describe major technical achievements, and some failures, that produced iconic successful variants. Successful imaging agents require industrialization for wide distribution and use.  So that we can understand the strengths, roles and limitations of academic and industrial researchers and developers, I will delve into the industrialization, the economics, and the commercialization of the agents. While molecular imaging spans half of the 130 years of imaging agents, by the standards of past development timelines, this newest age is really just getting started and will probably outpace all of the prior ages.

His education was at Knox College (BA Chemistry), Rice University (PhD Physical Chemistry) and Stanford University (NIH Research Service Fellow). His experience in diagnostic imaging began as a research scientist at New England Nuclear, Inc.  In 1981 he invented the first catalyst for production of Tc radiopharmaceutical myocardial perfusion agents, and early targeted molecular imaging (MI) agents using monoclonal antibodies at NEN/DuPont Pharmaceuticals. In 1986, working with E.R.

As President, CEO  and chief scientist at Bracco Research USA Inc, he and his team created in early 2000s two new clnically tested Molecular Imaging agents: a first in class targeted theranostic for prostate and breast cancer (177LuAMBA), and a first in class sub nM VEGF-R2 angiogenesis receptor-targeting peptide used in the targeted ultrasound contrast agent now in Phase-II clinical trials (BR55). He transiioned toacademics in 2009, focusing research on cancer imaging theranostics and teaching in entrepreneurial development. He is Associate Editor for contrast agents for the journals, Radiology, Magnetic Resonance Imaging and Investigative Radiology, served on NIH study sections in SBIR and Image Guided Therapy, has served on Expert Councils at the US Pharmacopeia, the elected Boards and as Officer of four professional societies, academic Scientific Advisory Boards in molecular Imaging, and on Scientific Advisory and governing Boards of public and private biopharmaceutical and chemical companies, and served on the Dean’s Scientific Advisory Board of New York University’s School of Science. He has authored over 200 publications including 105 peer-reviewed original research papers, 40 issued US patents (8 pending), 13 book chapters, and 40 reviews and editorials, with >10,000 citations and an H-Index of 54.
