The concern from the suboptimal imaging that was being talked about with thallium is based on radiation exposure to the patient, because it is a higher exposure than what we are looking at. It's also very difficult to schedule, and the patients are subjected to different types of procedures. The diagnostic yield is not that bad, but it comes at the price of higher radiation exposure. This is what we used in the 1970s, so this is a 30-year-old technique.
With our sensitivity toward radiation exposure to patients, it's not an optimal product to use at this point. It's good to put your finger in the dike to prevent it from collapsing, but it's not what we want to use. With the future innovative stuff, definitely we would. We are seeing some very interesting radiopharmaceuticals coming down the pipeline, but without having the infrastructure to use those on a regular basis in community hospitals, they won't have a big effect.
