Chest Computerized Tomography (CT) features of Corona Virus Disease 2019 (COVID-19) pneumonia are nonspecific, variable and sensitive in detecting early lung disease. Hence its usefulness in triaging in resource-limited regions.
To assess the pattern of chest CT scan findings of symptomatic COVID-19 patients confirmed by a positive RT-PCR in Ghana.
This study retrospectively reviewed chest CT images of 145 symptomatic RT-PCR positive COVID-19 patients examined at the Radiology Department of the Korle Bu Teaching Hospital (KBTH) from 8th April to 30th November 2020. Chi-Squared test was used to determine associations among variables. Statistical significance was specified at p≤0.05.
Males represent 73(50.3%). The mean age was 54.15±18.09 years. The age range was 5 months-90 years. Consolidation 88(60.7%), ground glass opacities (GGO) 78(53.8%) and crazy paving 43(29.7%) were the most predominant features. These features were most frequent in the elderly (≥65years). Posterobasal, peripheral and multilobe disease were found bilaterally. The most common comorbidities were hypertension 72(49.7%) and diabetes mellitus 42(29.2%) which had significant association with lobar involvement above 50%.
The most predominant Chest CT scan features of COVID-19 pneumonia were GGO, consolidation with air bronchograms, crazy paving, and bilateral multilobe lung disease in peripheral and posterior basal distribution.
2019 年冠状病毒病（COVID-19）肺炎的胸部计算机断层扫描（CT）特征是非特异性的、多变的，并且在早期肺部疾病的检测中具有敏感性。因此，在资源有限的地区，它在分诊中的作用是有用的。
评估加纳通过阳性 RT-PCR 确诊的有症状 COVID-19 患者的胸部 CT 扫描结果模式。
本研究回顾性分析了 2020 年 4 月 8 日至 11 月 30 日期间在科勒布教学医院（KBTH）放射科检查的 145 例有症状 RT-PCR 阳性 COVID-19 患者的胸部 CT 图像。卡方检验用于确定变量之间的关联。指定统计学意义为 p≤0.05。
男性占 73（50.3%）。平均年龄为 54.15±18.09 岁。年龄范围为 5 个月-90 岁。实变 88（60.7%）、磨玻璃密度影（GGO）78（53.8%）和铺路石征 43（29.7%）是最常见的特征。这些特征在老年人（≥65 岁）中最为常见。后基底、外周和多叶病变呈双侧分布。最常见的合并症是高血压 72（49.7%）和糖尿病 42（29.2%），这与超过 50%的肺叶受累有显著关联。
COVID-19 肺炎的最常见胸部 CT 扫描特征是 GGO、实变伴空气支气管征、铺路石征和双侧多叶肺疾病，分布在外周和后基底。
