Cs-131 tile implant–based intracranial brachytherapy requires coordinated interdisciplinary efforts spanning imaging, source management, implantation, post-implant planning, and radiation safety. The extent of inter-institutional variability in these practice...

Conventional LDR brachytherapy seeds rely on internal radiopaque markers that were incorporated to enhance radiographic visibility. With widespread adoption of modern 3D imaging modalities such as CT, the marker presence degrades seed localization and tissue...

Current LDR brachytherapy seeds contain internal radiopaque markers to enable visibility with radio-graphic imaging. However, this high-Z material introduces artifacts on CT that degrade image quality and may affect seed localization and dosimetric accuracy....
