Clinically Tenable Lung Dose Estimates in Y-90 Radioembolization from Truncated Maa-SPECT/CT with Unknown Lung Mass

Authors: Dan Giardina, John Karageorgiou, Chris Malone, Naganathan Mani, Allan Thomas

Affiliation: Washington University School of Medicine, Mallinckrodt Institute of Radiology, Washington University School of Medicine

Abstract Preview: Purpose: Relative to planar imaging, MAA-SPECT/CT offers more reliable lung shunt fraction (LSF) and lung mean dose (LMD) estimates in 90Y radioembolization. But lung truncation in SPECT/CT can limit ...

Influence of Treatment Site on Lung Shunt Fraction Estimation in 90y-Radioembolization Planning: Comparison of Planar and SPECT Imaging-Based Quantification

Authors: Lukas M. Carter, Jazmin Schwartz

Affiliation: Department of Medical Physics, Memorial Sloan Kettering Cancer Center, Memorial Sloan Kettering Cancer Center

Abstract Preview: Purpose: Accurate lung shunt fraction (LSF) estimation is essential for the safety and efficacy of 90Y-radioembolization therapy. This study compares planar gamma camera imaging and tomographic SPECT-...

Using Contrast-Enhanced Computed Tomography for Non-Invasive Lung Shunt Fraction Prediction in Yttrium-90 Radioembolization

Authors: Roger Eric Goldman, Adrianna Imani Johnson Carter, Talia Marx, Brahim Mehadji, Emilie Roncali, Catherine T. Vu

Affiliation: UC Davis, Department of Radiology, UC Davis Health

Abstract Preview: Purpose:
Accurate estimation of the Lung Shunt Fraction (LSF) is critical for yttrium-90 (90Y) radioembolization treatment planning to minimize risks of excessive lung irradiation due to arterio-ve...
