To compare the comfort levels of cone beam breast computed tomography (CBBCT) and digital mammography.
On 409 patients, CBBCT was performed within 1 week after conventional mammography. Patients evaluated their comfort by using an 11-point numerical rating scale (NRS-11) after completing the two examinations. The lower the score was, the more comfortable the examination modality was. The data was divided into different groups according to CBBCT scan mode (non-contrast mode, contrast-enhanced mode), age (≤44, 45∼59 and ≥60), body mass index (BMI) (<18.5 kg/m, 18.5∼23.9 kg/m, 24∼27.9 kg/m and ≥28 kg/m), and breast density (fatty-breast, dense-breast) to evaluate the performance of CBBCT comfort in different groups and to analyse the influencing factor of patient comfort. The paired rank sum test was used to compare the comfort between CBBCT and mammography.
Overall, the comfort of CBBCT was better than mammography (P < 0.05). CBBCT was more comfortable than mammography in both non-contrast and contrast-enhanced groups (P < 0.05). CBBCT was more comfortable than mammography in the ≤44, 45∼59 age groups (P < 0.05). There was no significant difference in the ≥60 age group (P = 0.5433). CBBCT was more comfortable than mammography in the BMI groups of 18.5∼23.9 kg/m, 24∼27.9 kg/mand ≥28 kg/m (P < 0.05). There was no significant difference in the <18.5 kg/m group (P = 0.43). CBBCT was more comfortable than mammography in both the fatty-breast and dense-breast groups (P < 0.05).

比较锥形束乳腺 CT（CBBCT）和数字乳腺 X 线摄影的舒适度。
在 409 例患者中，在常规乳腺 X 线摄影后 1 周内行 CBBCT 检查。患者在完成两次检查后，使用 11 点数字评分量表（NRS-11）评估舒适度。评分越低，检查方式越舒适。根据 CBBCT 扫描模式（非增强模式、增强模式）、年龄（≤44 岁、45∼59 岁和≥60 岁）、体质量指数（BMI）（<18.5 kg/m、18.5∼23.9 kg/m、24∼27.9 kg/m 和≥28 kg/m）和乳腺密度（脂肪型乳房、致密型乳房）将数据分为不同组，以评估 CBBCT 在不同组中的舒适度表现，并分析影响患者舒适度的因素。采用配对秩和检验比较 CBBCT 和乳腺 X 线摄影的舒适度。
总体而言，CBBCT 的舒适度优于乳腺 X 线摄影（P<0.05）。在非增强组和增强组中，CBBCT 的舒适度均优于乳腺 X 线摄影（P<0.05）。在≤44 岁和 45∼59 岁年龄组中，CBBCT 的舒适度优于乳腺 X 线摄影（P<0.05）。在≥60 岁年龄组中，差异无统计学意义（P=0.5433）。在 BMI 组 18.5∼23.9 kg/m、24∼27.9 kg/m 和≥28 kg/m 中，CBBCT 的舒适度优于乳腺 X 线摄影（P<0.05）。在<18.5 kg/m 组中，差异无统计学意义（P=0.43）。在脂肪型乳房和致密型乳房组中，CBBCT 的舒适度均优于乳腺 X 线摄影（P<0.05）。
