In this third episode on PET/MRI, we’ll focus on the overall goals for using MRI instead of CT with PET, namely less radiation and more accuracy. These properties have particular benefits in pediatrics and neurology that I’ll discuss. We’ll review the active area of protocol development with PET/MRI, including the issues in attenuation correction. Finally, […]

CPC-050 PET/MRI (Part 3) Attenuation and Future Protocols

While PET/MRI continues to be a very hot topic in the literature, we’re still not quite sure how to use it. So, to continue the discussion about PET/MRI, we’ll use the transition from PET to PET/CT as a model. We’ll look at the potential benefits PET/MRI may bring to TNM staging and discuss what may […]

CPC-049 PET/MRI (Part 2) TNM Staging and Acquisition

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 […]

CPC-048 PET/MRI (Part 1) The Promise of Less Dose

In this episode, I’ll continue to discuss the evaluation of response to therapy using PET. A number of factors affect when to assess therapy response and how to interpret the results, and there are differences between radiation therapy and chemotherapy. Within radiation therapy, it is very important to consider the particular disease, so I’ll discuss […]

CPC-047 Techniques for Consistent Evaluation

In this episode we will be looking at PET/CT and the evaluation of different therapeutic interventions. More and more, the interest in PET/CT is not only in the initial evaluation of disease, but also in the subsequent evaluation of therapy response. We will look at the literature to discuss the different recommended standards for defining […]

CPC-046 Therapy Assessment

A journal article I read recently had several amusing examples of  “unremarkable” words. This illustrates how easy it is for reports to  contain phrases that only the writer can clearly understand. While some  issues are caused by dictation technology and the tendency of us humans  to occasionally “zone out,” we can still improve the quality […]

CPC-045 Reporting – Combating Ambiguity

In this episode, I’ll discuss the issues of unclear language in written reports. With the growing use of EMR and demands for quick turnaround time, we’re spending less face time with our colleagues. This episode I’ll particularly focus on some studies concerning terminology, and how synonyms can make it difficult to determine to what degree […]

CPC-044 Reporting – Language Clarity

In this episode I’ll discuss prostate cancer and PET. Prostate imaging with PET remains unapproved for reimbursement by CMS, and we’ll examine several reasons why this is the case. One of the major limitations has to do with the tracers available, and along those lines I’ll talk about radiopharmaceuticals currently under investigation.
