摘要: Rationale and Objectives To assess the reproducibility of multidetector-row computed tomography (MDCT)-measured forced expiratory tracheal collapse in healthy volunteers. Methods Materials Fourteen healthy, nonsmoking volunteers (6 males, 8 females, mean age 48.7 ± 13.8 years) underwent repeat imaging 1 year after baseline dynamics employing same scanner technique (64-MDCT, 40 mAs, 120 kVp, 0.625 mm detector collimation) with spirometric monitoring total lung capacity exhalation. Cross-sectional area (CSA) trachea was measured cm above aortic arch at end-inspiration dynamic expiration, percentage (%) reduction lumen calculated. Measurements were compared between (Yr1) (Yr2) using correlation coefficients Bland-Altman plots. Results Mean end-inspiratory CSA 255.3 56 mm2 Yr1 255.1 52 Yr2; 125.6 60 132.1 58 % 51.7 18% 19% Yr2. differences Yr2 values 0.2 for CSA, 6.5 3.0% reduction. There excellent measures (r2 = 0.97, P Conclusion MDCT measurements are highly reproducible over time.
