Comparison of Radiation Dose and Image Quality between the 2nd Generation and 3rd Generation Dual- Source Single-Energy and Dual-Source Dual-Energy CT of the Abdomen
Purpose We compared the radiation dose and image quality between the 2nd generation and the 3rd generation dual-source single-energy (DSSE) and dual-source dual-energy (DSDE) CT of the abdomen. Materials and Methods We included patients undergoing follow-up abdominal CT after partial or radical n...

| description | Purpose We compared the radiation dose and image quality between the 2nd generation and the
3rd generation dual-source single-energy (DSSE) and dual-source dual-energy (DSDE) CT of the abdomen.
Materials and Methods We included patients undergoing follow-up abdominal CT after partial or
radical nephrectomy in the first 10 months of 2019 (2nd generation DS CT) and the first 10 months of
2020 (3rd generation DS CT). We divided the 320 patients into 4 groups (A, 2nd generation DSSE CT; B,
2nd generation DSDE CT; C, 3rd generation DSSE CT; and D, 3rd generation DSDE CT) (n = 80 each)
matched by sex and body mass index. Radiation dose and image quality (objective and subjective qualities) were compared between the groups.
Results The mean size-specific dose estimation of 3rd generation DSDE CT group was significantly
lower than that of the 2nd generation DSSE CT (42.5%, p = 0.013) and 2nd generation DSDE CT
(46.9%, p = 0.015) groups. Interobserver agreement was excellent for the overall image quality (intraclass
correlation coefficient [ICC]: 0.8867) and image artifacts (ICC: 0.9423).
Conclusion Our results showed a considerable reduction in the radiation dose while maintaining
high image quality with 3rd generation DSDE CT as compared to the 2nd generation DSDE CT and
2nd generation DSSE CT. |
