Nuclear Medicine News and Research

RSS

Nuclear medicine is a branch or specialty of medicine and medical imaging that uses radioactive isotopes (radionuclides) and relies on the process of radioactive decay in the diagnosis and treatment of disease. In nuclear medicine procedures, radionuclides are combined with other chemical compounds or pharmaceuticals to form radiopharmaceuticals.

New deep learning method could revolutionize heart health monitoring

Coronary artery disease is the leading cause of death globally. One of the most common tools used to diagnose and monitor heart disease, myocardial perfusion imaging (MPI) by single photon emission computed tomography (SPECT), uses a radioactive tracer and special camera to provide detailed images of blood flow to the heart, helping doctors detect coronary artery disease and other cardiovascular abnormalities.

Obesity crisis in the U.S. expected to worsen by 2050

Over the past three decades, there has been a startling increase in the prevalence of obesity across the USA, at least doubling in adult men and women (aged 25 and older) and older female and male adolescents (aged 15-24 years) since 1990, with the number of people living with overweight and obesity reaching over 208 million in 2021 - a trend set to continue in the coming decades without significant reform, according to a major new analysis from the Global Burden of Disease Study Collaborator Network, published in The Lancet.

Mini-protein AKY-1189 delivers targeted radiation to tumor cells

Researchers have shown for the first time that it is possible for a specially-designed 'mini-protein' to deliver a radiation dose directly to tumour cells expressing a protein on their cell surfaces called Nectin-4, which is often found in a number of different cancers.

Jefferson Lab team explores proton therapy as a safer cancer treatment

Radiation therapy techniques have been used for more than a century to treat cancers. Physicists in the Radiation Detector and Imaging group and associated with the Biomedical Research & Innovation Center (BRIC) at the U.S. Department of Energy's Thomas Jefferson National Accelerator Facility have been for several years pursuing radiation therapy technology improvements in collaboration with the Hampton University Proton Cancer Institute (HUPCI).

Study highlights disparities in stroke burden across regions

Although stroke is highly preventable and treatable, there has been a rapid rise in the global stroke burden between 1990 and 2021, due to both population growth and the rise of aging populations worldwide, as well as a substantial increase in people's exposure to environmental and behavioral risk factors.
