Summary
Photon-counting detector CT (PCD CT) abdominal imaging protocols at two centers show similar high-quality results with low radiation exposure. These findings support developing standardized protocols for consistent imaging and multicenter research.
Area of Science:
- Radiology
- Medical Imaging Technology
- Computed Tomography
Background:
- Photon-counting detector CT (PCD CT) offers superior spatial and contrast resolution for abdominal imaging.
- Reduced patient radiation dose is a key advantage of PCD CT.
- Optimal imaging protocols for PCD CT in abdominal applications are not yet standardized.
Purpose of the Study:
- To present and compare abdominal imaging protocols used at two tertiary care academic centers utilizing PCD CT.
- To identify commonalities and differences in acquisition and reconstruction parameters for PCD CT abdominal imaging.
Main Methods:
- A comparative review of PCD CT abdominal imaging protocols was performed by two abdominal radiologists.
- Protocols were analyzed based on acquisition parameters and reconstruction settings.
- Both institutions utilized QuantumPlus mode for PCD CT abdominal imaging.
Main Results:
- Despite minor variations in reconstruction kernels and iterative reconstruction levels, both centers achieved similar image quality.
- The implemented PCD CT protocols yielded high-quality abdominal images.
- Low radiation exposure was maintained across both protocols.
Conclusions:
- The study provides insights for standardizing PCD CT abdominal imaging protocols.
- Standardization can ensure consistent, high-quality imaging across institutions.
- These findings facilitate future multicenter research in PCD CT abdominal imaging.
