| Popis: | "BACKGROUND\/OBJECTIVES:. To assess the gender influence on radiation dose saving allowed by prospective ECG-triggered MDCT coronary angiography (P-MDCT-CA) in comparison with retrospective ECG-gated MDCT-CA (R-MDCT-CA). The influence of kilovoltage and body mass index on radiation dose and the impact of different parameters on image quality (IQ) and diagnostic confidence (DC), were also determined.. METHODS:. 64-slice MDCT-CA was performed in 176 patients: 66 R-MDCT-CA and 110 P-MDCT-CA. Effective dose was determined using ImpactDose software based on Monte Carlo method. Three point scales were used to assess IQ and DC on a segmental basis.. RESULTS:. Patients were divided into 4 groups according with the examination performed: group A (90 pts, coronary tree assessment with P-MDCT-CA); group B (55 pts, coronary tree assessment with R-MDCT-CA); group C (20 pts, bypass grafts assessment with P-MDCT-CA); and group D (11 pts, bypass grafts assessment with R-MDCT-CA). Effective dose was 68% lower for P-MDCT-CA than R-MDCT-CA for coronary artery studies (Gr. A=4.7±1.69mSv and Gr. B=14.9±4.4mSv; p |
