The introduction of smaller footprint, more sensitive Cadmium-Zinc-Telluride (CZT)-based detectors with improved spatial and energy resolution has enabled the design of innovative full-ring 360° CZT SPECT/CT systems (e.g., VERITON® and StarGuide™). With this transformative technology now aiming to become mainstream in clinical practice, several critical questions need to be addressed. This EANM position paper provides practical recommendations on how to use these devices for routine bone SPECT/CT studies, facilitating the transition from traditional planar whole-body imaging and conventional SPECT/CT to these novel systems. In particular, initial guidance is provided on imaging acquisition and reporting workflows, image reconstruction, and CT acquisition parameters. Given the emerging nature of this technology, the available evidence base is still limited, and the proposed adaptations in workflows and scan protocols will likely evolve before being integrated into definitive guidelines. In the meantime, this EANM position paper serves as a comprehensive guide for integrating these advanced hybrid SPECT/CT imaging systems into clinical practice and outlining areas for further study. [ABSTRACT FROM AUTHOR]

The letter to the editor discusses the challenges and opportunities of using full-ring 360° CZT bone imaging systems compared to traditional methods. The authors highlight the reduced administered activities and acquisition time of the CZT systems, but raise concerns about the cost and clinical utility compared to other technologies like 18F-NaF PET/CT. The letter also mentions the trend of nuclear medicine studies shifting towards PET/CT systems, which may impact the adoption of CZT SPECT/CT systems in clinical practice. [Extracted from the article]
