New 3D imaging technologies using X-rays and radiopharmaceuticals are advancing, but concerns about radiation exposure from computed tomography (CT) and hybrid imaging (PET/CT, SPECT/CT) are growing. This article discusses dose management tools and new techniques to mitigate risks for patients and staff.
Area of Science:
- Medical imaging technologies
- Radiopharmaceuticals and X-ray applications
- Radiation dose management
Background:
- Advancements in X-ray and radiopharmaceutical imaging technologies are ongoing.
- Computed tomography (CT) is beneficial but often overused without sufficient technique optimization.
- Hybrid imaging (e.g., PET/CT, SPECT/CT) combining multiple modalities is increasingly common.
Purpose of the Study:
- To provide information on developing 3D imaging technologies and clinical techniques.
- To discuss the radiation dose associated with these imaging modalities for patients and staff.
- To explore tools for improved radiation dose management.
Main Methods:
- Review of new imaging technologies utilizing X-rays and radiopharmaceuticals.
- Analysis of radiation dose implications from CT, PET, and SPECT investigations.
- Discussion of hybrid imaging techniques and their dose considerations.
Main Results:
- Increasing radiation exposure from CT is a significant concern, receiving wider attention.
- Radiation doses from PET and SPECT investigations are also becoming a focus of discussion.
- Development of new technologies and clinical techniques for 3D imaging is presented.
Conclusions:
- There is a need to balance the benefits of advanced imaging with radiation safety.
- Optimizing CT techniques and managing doses in hybrid imaging are crucial.
- Tools and strategies for effective dose management are essential for patient and staff safety.
