Recently the Coronavirus pandemic presented with different manifestations in different parts of the world, both on clinical examinations and on imaging. CT Scanning (CT Scan) chest is used for detailed evaluation of the different characteristic patterns determining the depth of disease. The study is aimed to assess the variations in spectrum of Covid-19 CT findings and relating severity (CT Severity Score) with the Clinical Symptoms in Bahawal Victoria Hospital, Bahawalpur.
In this cross-sectional study, patients referred to radiology department from outdoor for COVID screening were included from 1st May to 30th June 2020. Mean age range of patients was calculated, while presenting complaints and co-morbidities were tabulated in frequencies and percentages after analysis. Severity of symptoms and CT findings were correlated with biochemical and haematological tests.
Patients' age range from 25 to 85 years with 62% males and 38% females. Statistically no significant difference was observed in CTSS on gender basis. As sensitivity of RT PCR is about 70%, negative cases cannot be considered disease free and this is seen in this study as CT findings suggestive of COVID are seen in these patients. Using 40-point CT-SS, 11 patients had a score of >19 with severe diseases, while 14 patients had common disease with a score range of 11-18 and 35 patients had <10 score with mild or no symptoms.
In this study, a spectrum of patchy ground glass opacities, bilateral peripheral predominantly lower lung consolidations were observed. Quantitative analysis of inflammatory process as occurring in lungs in Coronavirus Disease 2019, using 40-point CTSS scoring on Imaging could provide a timely and objective approach towards identifying patients requiring intensive care and hospitalisation.
最近，冠状病毒在世界不同地区表现出不同的临床表现，无论是临床检查还是影像学表现。胸部 CT 扫描（CT 扫描）用于详细评估确定疾病深度的不同特征模式。本研究旨在评估 COVID-19 CT 表现的变化范围，并在 Bahawal Victoria 医院，Bahawalpur 评估与临床症状相关的严重程度（CT 严重程度评分）。
在这项横断面研究中，从 2020 年 5 月 1 日至 6 月 30 日，从户外转介到放射科的患者被纳入研究。计算了患者的年龄范围，同时分析了出现的症状和合并症的频率和百分比。将症状和 CT 表现的严重程度与生化和血液学测试相关联。
患者年龄范围为 25 至 85 岁，男性占 62%，女性占 38%。在性别基础上，CTSS 无统计学差异。由于 RT-PCR 的灵敏度约为 70%，阴性病例不能视为无疾病，这在本研究中可见，这些患者中可见提示 COVID 的 CT 表现。使用 40 分 CT-SS，11 例患者的评分>19，病情严重，14 例患者的评分范围为 11-18，35 例患者的评分<10，症状轻微或无症状。
在这项研究中，观察到斑片状磨玻璃影、双侧外周性下肺实变为主的一系列表现。使用 40 分 CTSS 评分对肺部炎症过程进行定量分析，可能为识别需要重症监护和住院治疗的患者提供及时和客观的方法。
