Key Points

To assess how much the radiation dose can be reduced using photon-counting detector CT while maintaining image quality compared to energy-integrating detector CT.
Compared imaging quality of PCD-CT and EID-CT visually at standard dose.
Used a head phantom to analyze detectability index (d') at various dose levels.
Evaluated clinical image equivalence of PCD-CT at reduced dose against EID-CT at standard dose using visual scores.
PCD-CT images had significantly higher visual scores than EID-CT at standard dose (3.73 vs. 2.56 for incudomalleolar joint, p < 0.001).
In the phantom study, d' was 0.12 at 50% dose for PCD-CT, indicating acceptable quality.
Mean visual scores of PCD-CT at 50% dose were equivalent to EID-CT at standard dose across all regions.
