2024 Molecular Imaging Preview

Road to RSNA 2024: Molecular Imaging Preview
By Will Morton
Theranostics could be cited for speeding in this year’s Road to RSNA. It's only been a few years since a dedicated track in nuclear medicine and molecular imaging was established at the meeting, and the practice already dominates it.

FAPI-PET/CT superior to FDG-PET/CT in liver cancer patients
By Will Morton
Ga-68 FAPI-PET/CT imaging appears superior to FDG-PET/CT for assessing hepatocellular carcinomas. In a large prospective trial, the approach was more accurate – enough so that it could possibly replace FDG-PET/CT in the future.

Can AI chatbots answer questions for patients on Lu-177 PSMA-617 therapy?
By Will Morton
In response to common questions from Lu-177 PSMA-617 patients, Gemini provided easy-to-understand answers and ChatGPT-4 demonstrated high accuracy, yet neither AI chatbot provided completely accurate answers to all questions.
