COVID-19对全球卫生系统产生了重大影响。这项研究的目的是评估放射科的成像量和成像类型如何受到不同地区COVID-19大流行的影响。研究方法：回顾性审查了Aseer地区（沙特阿拉伯南部）主要医院的成像量，包括从不同地点（门诊部、住院部和急诊部）转诊的所有病例。比较二零一九年及二零二零年的数据。使用t检验比较每月平均病例数。结果：2019年的总成像量为205，805，而2020年为159，107，总体减少22.7%。四月至六月及七月至九月期间均录得大幅跌幅，分别约为42. 9%及44. 4%。就地点而言，在4月至6月期间，门诊部下降幅度最大（下降76%），其次是急诊部（下降25%），住院部的影响最小，同期仅下降6.8%。根据检查方式类型，核医学、超声、MRI和乳腺X线检查的下降幅度最大，分别为100%、76%、74%和66%。我们的研究结果显示，与2019年相比，2020年的病例数量在统计学上显著减少（p值0.05），但乳房X线摄影手术除外。结论：由于COVID-19，放射学卷显著下降。放射学体积的总体减少取决于锁定的阶段/时期、位置和成像模式。
COVID-19 has had a significant impact on global health systems. The aim of this study was to evaluate how imaging volumes and imaging types in radiology departments have been affected by the COVID-19 pandemic across different locations. Methods: Imaging volumes in the Aseer region (in the south of Saudi Arabia) across main hospitals were reviewed retrospectively including all cases referred from different locations (outpatient, inpatient and emergency departments). Data for years 2019 and 2020 were compared. The mean monthly cases were compared using a t-test. Results: The total imaging volumes in 2019 were 205,805 compared to 159,107 in 2020 with a 22.7% overall reduction. A substantial decline was observed in both the April to June and the July to September periods of approximately 42.9% and 44.4%, respectively. With respect to location, between April and June, the greatest decline was observed in outpatient departments (76% decline), followed by emergency departments (25% decline), and the least impact was observed in inpatient departments, with only 6.8% decline over the same period. According to modality type, the greatest decreases were reported in nuclear medicine, ultrasound, MRI, and mammography, by 100%, 76%, 74%, and 66%, respectively. Our results show a statistically significant (p-value 0.05) decrease of cases in 2020 compared to 2019, except for mammography procedures. Conclusion: There has been a significant decline in radiology volumes due to COVID-19. The overall reduction in radiology volumes was dependent on the stage/period of lockdown, location, and imaging modality.
