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.

CLI could be promising technique for assessing tumor margins during breast-conserving surgery

Breast-conserving surgery is the primary treatment for early-stage breast cancer, but more accurate techniques are needed to assess resection margins during surgery to avoid the need for follow-up surgeries.

Patients with pulmonary embolism experience long term limitations to physical stamina

A multi-centre clinical study, led by Dr. Susan Kahn at the Jewish General Hospital (JGH), determined that nearly half of the patients who suffer a pulmonary embolism (PE) -- a blood clot in the lung -- experience long term limitations to their capacity for physical activity and that this had a negative impact on their quality of life.
