Abstract Purposes The primary objective of this retrospective study was to assess whether the CT dose delivered oncologic patients different in a subspecialty radiology department, compared general department. secondary explorative image quality examinations two settings. Materials and methods Chest abdomen scans performed for indications were selected from department By using radiation management platform, we extracted index (CTDI vol ) length product (DLP) both each phase entire exams. For evaluation, calculated signal-to-noise ratio (SNR) contrast-to-noise (CNR) at level liver aorta. A P-value < 0.05 considered significant. Results total 7098 included. CTDI evaluated 12,804 phases; DLP 10,713 phases 6714 examinations. overall significantly lower median (IQR) 5.19 (3.91–7.00) 5.51 (4.17–7.72), IQR 490.0 (342.4–710.6) 503.4 (359.9–728.8), p 0.001 = 0.01, respectively. showed no significant difference departments, with 4.03 (2.82–5.51) 3.84 (3.09–4.94) SNR Liv ( 0.58); 4.81 (2.70–7.62) 4.34 (3.05–6.25) Ao 0.30); 0.83 (0.20–1.89) 1.00 (0.35–1.57) CNR 0.99); 2.23 (0.09–3.83) 1.01 (0.15–2.84) 0.24) 0.58), 0.30), 0.99) 0.24). Conclusion In protocols are optimized leading doses without degradation.
