- Photon-counting CT (PCCT) compared to Energy-integrating Detector CT (EID CT) in lung cancer imaging.
- PCCT used a quadruple-low protocol: low radiation dose, reduced contrast agent injection rate, volume, and concentration.
- PCCT reduced radiation dose by 55% and contrast agent usage significantly compared to EID CT.
- PCCT showed a 0% incidence of contrast-induced nephropathy (CIN) versus 7.9% with EID CT.
- PCCT provided higher objective SNR and CNR in lung lesions and parenchyma.
- PCCT demonstrated superior subjective image quality and increased diagnostic confidence.
- Results were consistent in sensitivity analysis, reinforcing PCCT's advantages.
