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.

Y90 radioembolization often requires both fluoroscopy and CBCT to guide the complex treatment procedure. However, radiation data in the form of RDSRs and Dose Sheets are usually combined across these imaging modalities, making it harder to understand their un...

Accurate radiation documentation is essential for assessing patient risk during fluoroscopically guided procedures. Radiation Dose sheets are commonly used but may omit exposure details while DICOM Radiation-Dose-Structured-Reports (RDSRs) provide more compre...

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...
