New Imaging Approach Improves Care for Men at Risk of Prostate Cancer
Monday, March 29, 2021
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.
Future Physician-Scientists Spent a Year in IRP Labs
Monday, September 21, 2020
Many doctors not only treat patients directly, but also make valuable contributions to research that will improve medical care in the future. Each one of these talented ‘physician-scientists’ began his or her research career under the guidance of a more senior scientist. At the NIH, the Medical Research Scholars Program (MRSP) provides just such an experience to promising young medical students from all across the United States.
Five Questions with Dr. Nehal Mehta

Most Americans know someone who has been affected by heart disease. Despite its status as the leading cause of death in the U.S. today, rates of heart disease have actually been steadily falling since they hit their peak in 1968. In fact, between 1970 and 2005, the life expectancy of the average American increased over 70 percent due in part to reductions in heart disease-related deaths.
Research conducted by IRP scientists has played a key role in curbing the heart disease epidemic by helping identify now well-known risk factors for heart disease, such as high blood pressure, obesity, and physical inactivity. However, not all risk factors are so commonly known. A 2017 study by IRP Lasker Clinical Research Scholar Nehal Mehta, M.D., M.S.C.E., revealed that untreated psoriasis — a chronic, relapsing, inflammatory skin disease — is linked to an elevated risk for premature coronary artery disease. Dr. Mehta’s research demonstrated a strong link between psoriasis-induced skin inflammation and and inflammation of the blood vessels, a precursor to heart disease. Through this study, the largest ongoing study of individuals with psoriasis to-date, Dr. Mehta’s team has concluded that controlling psoriasis-associated skin disease could be an important means of reducing cardiac risk in this population.
A Conversation with Dr. Lori Beason-Held

Expert estimates suggest that more than 5.5 million Americans may have dementia caused by Alzheimer’s, a disease currently ranked as the sixth-leading cause of death in the United States. Because of the condition’s growing prevalence and profound consequences for patients, understanding Alzheimer’s disease and other forms of cognitive decline is an important goal within the Intramural Research Program.
One example of the IRP’s many contributions to the field of Alzheimer’s research is a 2013 study that detected brain changes in older adults who would go on to develop cognitive impairment years before their memory began to fail. This research, led by IRP staff scientist Lori Beason-Held, Ph.D., aimed to understand who might be susceptible to developing Alzheimer’s disease and what factors contribute to the development of the disease before symptoms appear.

For Americans and others living outside the tropics, a mosquito bite is nothing more than an itchy inconvenience, but for billions of others, it can lead to a life-or-death battle with malaria. In some cases, the illness can wreak havoc on the brain. A new IRP study has used magnetic resonance imaging (MRI) technology to demonstrate that an investigational therapy can reverse that damage in mice.

With summer winding down, it's about time we took another dive into some NIH history! These new additions to the NIH Stetten Museum collection feature some of the most prominent investigators ever to walk the NIH campus, including a Nobel prize winner and a scientist who made important discoveries about how electricity travels between neurons.

To paraphrase President Obama from his guest editorial in the November issue of Wired magazine, there’s never been a better time to be alive. One NIH institute leading us into the future is the National Institute of Biomedical Imaging and Bioengineering (NIBIB), which supports avant-garde investigators at the nexus of engineering and the physical and life sciences with innovations that improve global health.

If you were going to train an artificial intelligence (AI) system to understand and accurately diagnose medical images, what kind of information do you think would be most effective: lots of general image data, or small amounts of specific data?

Scientists in the NIH Intramural Research Program (IRP) go to work each day in the biomedical equivalent of a candy store. The advanced equipment and shared tools readily available to researchers doing basic, translational, and clinical science in the IRP are unmatched anywhere else, which enables high efficiency and productivity within the IRP’s unique discovery model.
