M. Alex Brown, Ph.D. radiochemistry: Medical isotopes are a class of radioactive isotopes used by hospitals to monitor the body’s functions and destroy cancerous tissues. They’re different from x-rays and CT scans that use accelerators to generate radiation. As of 2012 nearly 40 million people every year receive a diagnostic procedure with a medical isotope in what’s estimated to be a $5 billion/year industry, according to Radiation therapy extends to the treatment of non-Hodgkins lymphoma, HIV, liver cancer, thyroid cancer, breast cancer, and more.

David Kramer: The first US production in 30 years of molybdenum-99, the parent isotope of the most widely used medical radioisotope, is expected to begin within weeks after federal regulators approved a manufacturing process developed by Wisconsin-based NorthStar Medical Radioisotopes. NorthStar received $25 million in matching funds from DOE for development of the neutron capture process and $14.8 million of an expected $25 million total for its accelerator approach.

Society of Nuclear Medicine and Molecular Imaging: A nuclear medicine scan may locate prostate cancer recurrence after radical prostatectomy early after disease recurrence and could help guide salvage radiotherapy, according to new research from the University of California Los Angeles (UCLA). The study utilizes PET/CT with gallium-68 prostate-specific membrane antigen (68Ga-PSMA-11).

European Association of Nuclear Medicine: Many people associate the term, nuclear medicine, with dangerous radiation. These concerns are unfounded. While it is true that radioactive substances are used, the exposure doses to the patient are so low according to the European Association of Nuclear Medicine (EANM) that they do not call into question the benefits of the diagnostic and therapeutic possibilities of nuclear medicine.

José Pascual Pérez Campos y Eduardo Larrea y Richerand han realizado una muy cuidadosa reseña histórica del desarrollo en México de uno de los grandes avances de la tecnología médica de este siglo. El impacto de estas tecnologías en el diagnóstico y tratamiento de las enfermedades ha modificado favorablemente la atención de numerosas enfermedades. Los conocimientos que sirvieron de base para crear armas de destrucción masiva, afortunadamente para la conciencia de los investigadores de este campo, se han convertido en un arma eficaz en beneficio de los enfermos. El grupo de científicos de Oak Ridge asociados con investigadores de diversas universidades lograron avanzar de los iniciales usos del Yodo para el diagnóstico y tratamiento de enfermedades del tiroides a diversos implementos tecnológicos que han permitido estudiar el cuerpo humano con una precisión increíble.

Dr. Rodrigo Muñoz Casillas, Dra. Nora E. Kerik Rotenberg, Dr. Iván Eudaldo Díaz Meneses, M. en C. Carlos Alberto Reynoso Mejía. Instituto Nacional de Neurología y Neurocirugía “Manuel Velazco Suárez”: La Tomografía por Emisión de Positrones (PET) es la técnica de diagnóstico por imagen de medicina nuclear en la cual se aplica al paciente un radiofármaco (unión de un fármaco con farmacocinética conocida a un átomo radiactivo emisor de positrones). La PET/CT cerebral con 18F-FDG (análogo de la glucosa) evalúa el metabolismo glucolítico cerebral ya que éste proporciona aproximadamente el 95% del ATP necesario para la función cerebral.

IAEA, International Energy Agency, Jeremy Li: As the major research reactors that supply Mo-99 age and cease production, the alternative method discussed in the paper offers a simplified way to diversify production and help ensure continued supplies of Mo-99 so that nuclear medicine services are not interrupted. In 2009, reactors producing Mo-99 in Canada and the Netherlands were temporarily shut down for necessary repairs and maintenance. This caused major disruption in health care services worldwide, leading to cancelled medical scans and postponed operations, and in some cases requiring medical professionals to revert back to using old, less effective techniques.
