In this episode, we’ll dive into the exciting new technology of PET/MRIs. We can learn a lot from our history, and I’ll discuss what image fusion and PET/CT hardware have provided us over the years. But while PET/CT has certainly helped our accuracy in staging, I’ll use a pediatric example to point out how PET/CT can also lead to more dose. Because of the possibility of lower dose and other potential gains, I’ll discuss the reasons PET/MRI scanners hold such promise.
