Possible Shortage of Xenon-133

Due to the planned maintenance of the Canadian National Research Unit (NRU) Mo-99 reactor shutdown, the United States will be facing a temporary shortage of Xenon-133 (Xe-133) for approximately one month. As of now, a replacement supply is unavailable as the alternative supplier commercially approved for the U.S. market is also unable to produce the product at the time.

Xe-133 is a critically important diagnostic tool that is instrumental in the timely and accurate diagnosis of a number of pulmonary conditions, including pulmonary embolism, a condition that is potentially fatal for patients. The use of Xe-133 is highly used by clinicians during emergency procedures in order to prevent potentially fatal conditions, including those involving problems with cerebral blood flow.
