Synopsis
The doctors first discuss the structure of their Y90 service lines, including the impact of multidisciplinary tumor boards and clinics on time to treatment for liver cancer patients. They then talk through their technical preferences—whether to use glass or resin, preferred dosimetry guidelines and apps, and the dosimetry softwares that they use in treatment planning. The doctors also discuss the utility of the T2N ratio, advanced imaging like cone beam CT, and angiographic targeting software—emphasizing how these tools can help achieve the delicate balance of preserving normal tissue while treating as much tumor as possible. This episode also highlights the importance of collaboration between academic and private practices to optimize patient care and treatment outcomes.
