To analyze the impact of the COVID-19 pandemic in 2020 on the radiological imaging volume in Germany.
In this retrospective multicenter study, we analyzed CT and MRI examinations of 7 radiology institutes across Germany from January to December 2020. The imaging volume was compared to 2019 (Wilcoxon-Mann-Whitney test). Modality, patient service locations, and examined body parts were assessed in consideration of time periods of the pandemic. In addition, correlation with the incidence of SARS-CoV-2 cases and associated death was performed (Spearman-test).
In total, in 2020, imaging volume declined by 4 % (n = 8314) compared with 2019 (p < 0.05). The hard lockdown during the first pandemic wave (calendar week 12-16, March 22 - April 19) revealed the highest decrease with 29 % (n = 894, p < 0.01), with the greatest decrease in CT (36 % vs. MRI 26 %), outpatients (38 %, p < 0.01), and imaging of the spine and extremities (51-72 %, < 0.05 - p < 0.01). Examinations referred from the emergency department (-13 %, p < 0.05) and CT of the chest (-16 %, p < 0.05) were least affected. With the end of the first wave, gradual normalization of the imaging volume was observed and persisted until the end of the observation period. A reduction of imaging volume negatively correlated with the incidence of SARS-CoV-2-positive cases and associated deaths (r = 0.28 and 0.49, p < 0.05 and p < 0.001).
The COVID-19 pandemic was associated with a significant temporary decline in imaging volume. After the first lockdown period, a quick recovery was observed with radiologic imaging examinations steadily approaching prior-year figures.
· This study assesses the impact of dynamic pandemic activity on radiological imaging in a multicenter analysis in Germany.. · The COVID-19 pandemic was associated with a temporary decline in CT and MRI scans.. · Relaxation of restrictions was associated with fast normalization of imaging volumes to prior-year levels, which persisted until the end of the year.. · Significant catch-up effects were not observed..

分析2020年新冠疫情对德国放射影像检查量的影响。
在这项回顾性多中心研究中，我们分析了德国7家放射学机构在2020年1月至12月期间的CT和MRI检查。将影像检查量与2019年进行比较（Wilcoxon-Mann-Whitney检验）。考虑到疫情期间，对检查方式、患者就诊地点和检查的身体部位进行了评估。此外，还进行了与SARS-CoV-2病例发病率和相关死亡的相关性分析（Spearman检验）。
总体而言，2020年的影像检查量与2019年相比下降了4%（n = 8314）（p < 0.05）。疫情第一波期间的严格封锁（日历周12 - 16，3月22日至4月19日）期间下降幅度最大，为29%（n = 894，p < 0.01），其中CT下降幅度最大（36%，而MRI为26%），门诊患者检查量下降（38%，p < 0.01），脊柱和四肢的影像检查下降（51 - 72%，0.05 < p < 0.01）。急诊科转诊的检查（-13%，p < 0.05）和胸部CT检查（-16%，p < 0.05）受影响最小。随着第一波疫情结束，影像检查量逐渐恢复正常，并持续到观察期结束。影像检查量的减少与SARS-CoV-2阳性病例的发病率和相关死亡呈负相关（r = 0.28和0.49，p < 0.05和p < 0.001）。
新冠疫情与影像检查量的显著暂时下降有关。在第一次封锁期后，观察到快速恢复，放射影像检查量稳步接近上一年的数字。
· 本研究在德国的多中心分析中评估了动态疫情活动对放射影像的影响。· 新冠疫情与CT和MRI扫描的暂时下降有关。· 限制措施的放宽与影像检查量快速恢复到上一年水平有关，这种情况一直持续到年底。· 未观察到显著的追赶效应。
