Problems with the world production and supply of molybdenum are leading to shortages of radioisotopes for nuclear medicine imaging tests, according to an editorial in the journal Nuclear Medicine Communications, official journal of the British Nuclear Medicine Society (BNMS).

The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health, a leading provider of information and business intelligence for students, professionals, and institutions in medicine, nursing, allied health, pharmacy and the pharmaceutical industry.

International co-operation is needed to meet the challenges of maintaining a stable, reliable supply of radioactive tracers for essential bone, heart, and other imaging studies, according to the article by Alan C. Perkins of University of Nottingham and Gill Vivian of Plymouth Hospitals NHS Trust.

Supply Problems Disrupt Nuclear Medicine Services
Over the years, production and distribution of molybdenum - used to produce radiopharmaceuticals containing technetium-99m, widely used in nuclear medicine - has been highly reliable. However, problems have arisen due to the age of the commercial reactors that make molybdenum. All but one of the six reactors worldwide are more than 40 years old.

In the last two years, shutdowns of reactors in Canada and the Netherlands have led to disruptions in the supply of molybdenum to hospital nuclear medicine departments in the United Kingdom, Europe, and North America. With supplies reduced to 30 percent of normal, departments have had to adapt to make the most effective and efficient use of their supplies.
