新型冠状病毒肺炎疑似与确诊患者的胸部X线表现比较

目的 探讨新型冠状病毒肺炎（corona virus disease 2019，COVID-19）疑似患者与确诊患者的胸部X线表现。方法 收集2020年1月21日至3月4日首都医科大学大学宣武医院45例疑似COVID-19患者与9例确诊COVID-19患者的临床和胸部X线资料，对其X线表现进行比较分析。结果 45例疑似病例中32例X线表现可见异常，肺内病变最常累及左侧（18例）、下肺野（24例）、中带（23例），病变以单发（21例）、斑片状（29例）、模糊影（24例）常见。9例确诊病例中5例胸部X线阳性，肺内明确病变最常累及右侧（4例）、下肺野（5例）、中带（4例），病变仍以单发（4例）、斑片状（5例）、模糊影（4例）常见。两组病例除病变分布侧别的差异有统计学意义外（P<0.05），在胸部X线的其他异常表现差异均无统计学意义（P>0.05）。结论 作为初筛手段，胸部X线检查对疑似病例与确诊病例的鉴别困难。

Comparison of chest radiograph images between suspected and confirmed cases of COVID-19

Objective To explore the value of chest radiograph images between suspected and confirmed COVID-19. Method The clinical data and chest radiograph of 45 patients with suspected COVID-19 and 9 confirmed COVID-19 in our hospital from January 21 to March 4, 2020 were analyzed. Results There were 32 positive cases in 45 suspected cases. The most frequently involved area was the left lung (18 cases), lower lung field (24 cases), and the middle zone (23 cases). The most common manifestations of lesions are single (21 cases), patchy (29 cases), and blurred shadow (24 cases). Among 9 confirmed cases, 5 cases showed positive chest radiograph. The most frequently involved area was the right lung (4 cases), lower lung field (5 cases), and middle zone (4 cases).The most common manifestations of lesions are single (4 cases), patchy (5 cases), and blurred shadow (4 cases). Except for the difference of lesion distribution side (P<0.05), there were no statistically significant differences in other abnormal chest X-ray findings between the two groups (P>0.05). Conclusion As a routine screening method, it is difficult to distinguish confirmed cases from suspected cases with chest X-ray alone.
