Retrospective Study of Lung Shunt Fraction Using Data Acquired from 3D SPECT and 2D Planar Imaging
A modified lung shunt fraction (LSF) based on conventional 2D planar imaging data was proposed. That modified LSF can reduce the 2D overestimation errors and get closer results with 3D SPECT images.

BLUE RIBBON POSTER RADIOPHARMACEUTICALS: Y‑90 Bremsstrahlung SPECT on Nai and CZT Systems Using Energy‑Window-Based Scatter Compensation: Initial Phantom and Clinical Evaluation with Practical Protocol Implications
Direct imaging of Y‑90 bremsstrahlung with SPECT remains challenging because the continuous photon energy spectrum introduces scatter and septal penetration which reduces contrast and complicates quantitative reconstruction. Optimal energy‑window placement is...
