Assessment of Alpha-Fetoprotein As a Prognostic Factor of Overall Survival for HCC Patients Undergoing 90Y-Glass Trans-Arterial Radioembolization

Authors: Srinivas Cheenu Kappadath, James Long, Armeen Mahvash, Anna Marks, Ajalaya Teyateeti

Affiliation: Mahidol University, The University of Texas MD Anderson Cancer Center, UT MD Anderson Cancer Center

Abstract Preview: Purpose:
Alpha-fetoprotein (AFP) has been implicated as prognostic factor of overall survival (OS) for hepatocellular carcinoma (HCC). We present a statistical approach to determine optimal AFP-cut...

Evaluation of MR Proton Density Fat Fraction (PDFF) for Bone Marrow Protection in RT

Authors: Li Tong, Chuyan Wang, Zhengkui Wang, Yingli Yang, Jie Zhang

Affiliation: Shanghai United imaging Healthcare Advanced Technology Research Institute, Shanghai United Imaging Healthcare Co., LTD, Department of Radiology, Ruijin Hospital, Institute for Medical Imaging Technology, Ruijin Hospital

Abstract Preview: Purpose:
Pelvic radiotherapy (RT)-induced bone marrow (BM) damage affects patient prognosis by causing hematologic toxicity. However, consensus on BM-sparing (BMS) RT is still lacking, owing to the...

Feasibility of Zap-X Beam Quality Assurance Using Cherenkov Radiation

Authors: Xiaodong Wu, Xingchen Zhai, Weizhao Zhao

Affiliation: University of Miami

Abstract Preview: Purpose: The ZAP-X is a self-contained, self-shielded radiosurgery system utilizing a 3MV LINAC. Its self-shielded design, poses challenges for conventional beam quality assurance (QA) methods. This s...
