| 目的 探讨新型冠状病毒肺炎患者肺超声与CT影像相关性，肺超声对COVID-19患者肺部病变评估的作用。 方法 超声医师采用单侧六分区法对25例COVID-19患者进行床旁肺超声顺序盲扫，观察每个肺区胸膜线厚度、形态、完整性，胸膜滑动征，A线，B线的分布、数目、融合范围，肺实变位置、内部回声、范围，是否有胸腔积液等伴随征象。行半定量评分，与同期胸部CT影像对照，应用SPSS24. 0统计学软件分析右肺、左肺、全肺超声评分与CT病灶体积占比相关性。比较普通型、（危）重型患者全肺超声评分、CT病灶体积占比。 结果 全肺总评分最低为0分（1例），最高为22（1例）。患者右肺、左肺超声评分比较差异有统计学意义（P<0.05），R1-R6、L1-L6区评分比较差异有统计学意义（均P<0.05）。右肺、左肺、全肺超声评分与CT病灶体积占比相关系数分别为0.942、0.956、0.922（均P<0.01）。全肺超声评分普通型[5（4.25）]与（危）重型[14（9.5）]比较；全肺CT病灶体积占比普通型[4.3（6.85）%]与（危）重型[22.4（20.25）%]比较，差异均有统计学意义（均P<0.01）。COVID-19患者肺超声评分与CT病灶体积占比具有显著相关性。 结论 以CT为参照，床旁肺超声对COVID-19患者肺部病变的无创性评估具有重要意义。 |

| Abstract: |
| Objective To explore the correlation between lung ultrasonography and CT images in patients with COVID-19, and the role of lung ultrasound in evaluation of lesions in COVID-19 patients. Methods Doctors performed bedside lung sequential blind scan in 25 patients with COVID-19. The thickness, shape and integrity of pleural line, A line and the characteristics of B line, consolidation and pleural effusion were observed. Ultrasound semi-quantitative scoring procedures were performed and compared with chest CT images in the same period. SPSS24.0 statistical software was used to analyze the correlation between right, left, whole lung ultrasound score and the proportion of CT lesion volume. Compare the lung ultrasound score and the proportion of CT lesion volume of the general and severe(critical) group. Results The lowest total score of the whole lung was 0 (1 case) and the highest was 22 (1 case). There was significant difference in the total lung ultrasound scores of right lung and left lung (P<0.05)，as well as R1 to R6 areas and L1 to L6 areas (P<0.05). The correlation coefficients between the lung ultrasound scores of right, left, whole lung and the proportion of CT lesion volume were 0.942, 0.956 and 0.922, respectively（P<0.01）. The differences of lung ultrasound scores of general group [5 (4.25)] and severe(critical) group [14 (9.5)],the proportion of CT lesion volume of general group [4.3 (6.85)%] and severe(critical) group [22.4 (20.25) %] were statistically significant (both P<0.01). The lung ultrasound score in patients with COVID-19 is significantly correlated with the proportion of lesion volume in CT. Conclusion Compared with CT, bedside lung ultrasound plays an important role in non-invasive evaluation of pulmonary lesions in patients with COVID-19. |
