Currently there is a big shortage in Nuclear Medicine (NM) Technicians (with PET and CT certs as well) and ECHO technicians (particularly those with certification with infant ECHO). The hospital I work in started an ECHO school because so many leave to travel or go to the cardiology offices. It is the only way we can keep staffed. NM-- we are reduced in the cardiology offices to hiring on one travel tech per office (we used to have 3 techs at a time). With one tech, they have to provide extra nursing support and it is almost harder to keep office nurses.
