Yes, it will be a lot better if you all have the material in front of you.
Diagnostic imaging is critical to assess patients and to determine treatments and further testing. Nuclear medical procedures make up an important fraction of diagnostics, and the vast majority, more than 80%, rely on technetium-99m. This is a technical term, but it's basically the medical isotope that we talk about that is in short supply these days. It is itself derived from another isotope called moly-99 or molybdenum-99, and we will show later how this evolves through the supply chain.
This particular medical isotope performs a critical role in the diagnosis of heart disease and is used in cancer diagnosis as well, through bone and internal organ scans. I'll turn to my colleague from the Department of Health to go through slides 3 and 4, which give you a better sense of the use of technetium-99m, which again is the medical isotope.
There are many medical isotopes. There is iodine of different varieties. Technetium-99 is the one that is in short supply right now, the one we are talking about with regard to the shortage.
