    OBJECTIVES: To determinethe agreement on the quantification of HRCT. METHODS: HRCT scans of 43 patients with bronchiectasis were analyzed by two radiologists. Findings were graded with a score, and kappa values and overall agreement were calculated. RESULTS: Measurement and appearance of bronchiectasis showed moderate interobserver (k = 0.45 and k = 0.43, respectively) and intraobserver agreement (k = 0.54 and k = 0.47, respectively). Agreement on the presence of mucous plugging was fair(central distribution: overall interobserver agreement of 68.3%, k = 0.39 for intraobserver agreement; peripheral distribution: k = 0.34 and k = 0.35 for inter- and intraobserver agreement, respectively) and forperibronchial thickening (k = 0.21 and k = 0.30 for interand intraobserver agreement, respectively). Agreement on the detection of opacities, ground-glass areas, and cysts/bullae was fair (k = 0.39, overall agreement of 64.3%, and k = 0.47 for interobserver agreement, and overall agreement of 71.9%, k = 0.24, and k = 0.44for intraobserver agreement, respectively). After qualitative analysis of the findings of bronchiectasis on HRCT, the total score for each patient was calculated, showing excellent correlation between observers (intraclass correlation coefficient of 0.85 for interobserver agreement and of 0.81 for intraobserver agreement). CONCLUSION: HRCT findings of bronchiectasis showed fair agreement between observers. After final analysis of the findings using the proposed score, we observed an excellent inter- and intra-observer correlation.
