To develop a protocol for ultrasound diagnostics of COVID-19 pneumonia and to assess the diagnostic capabilities of the method in comparison with computer tomography (CT).
The study included 59 patients with a new coronavirus infection. In order to identify changes in the lung tissue characteristic of a new coronavirus infection, we used a special protocol for ultrasound of the lungs, which was developed by us in such a way that the data obtained were compared by segment with the results of CT of the lungs.
When comparing the results of lung ultrasound with the data of CT diagnostics, according to the new protocol, the percentage of lung tissue damage during ultrasound of the lungs averaged 70.8% in the group [62.5; 87.5], and according to the results of CT 70.0% [60.0; 72.5] (p=0.427). Thus, the ultrasound of the lung lesions was almost completely consistent with the changes revealed by CT. In order to assess the diagnostic value of lung ultrasound in identifying severe lung tissue lesions corresponding to CT 34, ROC analysis was performed, which showed the high diagnostic value of lung ultrasound in identifying severe lung tissue lesions.
A new protocol was developed for assessing the severity of lung tissue damage according to ultrasound data, which showed a high diagnostic value in detecting COVID-19 pneumonia in comparison with CT. The results obtained give reason to recommend this protocol of ultrasound of the lungs as a highly sensitive method in diagnosing the severity of COVID-19 pneumonia. Its application is very important for dynamic examination of patients, especially in conditions of low availability of CT.
制定新冠病毒肺炎的超声诊断方案，并与计算机断层扫描（CT）比较评估该方法的诊断能力。
该研究纳入了59例新冠病毒感染患者。为了识别新冠病毒感染所特有的肺组织变化，我们采用了一种特殊的肺部超声检查方案，该方案的制定方式使得所获得的数据按肺段与肺部CT结果进行比较。
根据新方案，将肺部超声结果与CT诊断数据进行比较时，肺部超声检查时肺组织损伤百分比在该组平均为70.8%[62.5；87.5]，而根据CT结果为70.0%[60.0；72.5]（p=0.427）。因此，肺部病变的超声检查结果与CT显示的变化几乎完全一致。为了评估肺部超声在识别与CT 34相对应的严重肺组织病变中的诊断价值，进行了ROC分析，结果显示肺部超声在识别严重肺组织病变方面具有较高的诊断价值。
制定了一种根据超声数据评估肺组织损伤严重程度的新方案，与CT相比，该方案在检测新冠病毒肺炎方面具有较高的诊断价值。所得结果有理由推荐这种肺部超声检查方案作为诊断新冠病毒肺炎严重程度的高灵敏度方法。其应用对于患者的动态检查非常重要，尤其是在CT可用性较低的情况下。
