IRP’s Peter Choyke Elected to National Academy of Medicine

New Imaging Approach Improves Care for Men at Risk of Prostate Cancer

Dr. Peter Choyke

The National Academy of Medicine (NAM), first established in 1970 by the National Academy of Sciences as the Institute of Medicine (IOM), is comprised of more than 2,000 elected members from around the world who provide scientific and policy guidance on important matters relating to human health. Election to the NAM is considered one of the highest honors in the fields of health and medicine and recognizes individuals who have not only made critical scientific discoveries but have also demonstrated a laudable commitment to public service.

IRP senior investigator Peter Choyke, M.D., was elected to the NAM last year for his pioneering advances in imaging technologies for prostate cancer, which have improved diagnosis and treatment. Dr. Choyke, who directs the Molecular Imaging Branch at the National Cancer Institute (NCI), harnessed artificial intelligence to superimpose images from magnetic resonance imaging (MRI) scans onto images taken in real time using ultrasound, thereby enhancing doctors’ ability to non-invasively examine prostate tumors. This allows doctors to be more precise with their biopsies, thereby lowering discomfort and the risk of nerve damage when they take samples of the tumor. Better yet, if the images show no signs of cancer, patients can skip the invasive biopsy procedure entirely and just continue regular monitoring and checkups.

Ultrasound-Based Technique Produces Fertile Ground for Therapeutic Stem Cells

Every good gardener knows the importance of fertilizing the soil before planting seeds, and evidence is accumulating that a similar concept applies to the human body when it comes to experimental stem cell therapies. A new IRP study has uncovered how a medical technology called pulsed-focused ultrasound boosts the healing potency of a particular stem cell treatment.
