Hypothesis
This study aimed to quantify the impact of 99mTc on 90Y bremsstrahlung-SPECT/CT image quality and to establish an optimised imaging protocol.
Conclusion
The study found that advanced reconstruction techniques significantly improved post-treatment image quality in dual-isotope settings.
Supporting Evidence
- Image quality degradation was noted in dual-isotope settings even when using an optimised protocol.
- Advanced reconstruction techniques markedly improved post-treatment image quality.
- The highest contrast recovery coefficients were achieved with an advanced Monte Carlo-based reconstruction.
Takeaway
This study looked at how a certain type of imaging can be affected when two different substances are used together, and it found ways to make the images clearer.
Methodology
The study used a NEMA IQ phantom to measure contrast recovery coefficients (CRCs) for different imaging protocols.
Limitations
The study used a phantom model that may not fully represent clinical scenarios, and the imaging protocol lacked background compensation.
