| 目的 探讨新型冠状病毒肺炎（Novel Coronavirus Pneumonia ，NCP）早期胸部高分辨率CT（HRCT）影像学表现。方法 分析31例经确诊的NCP胸部HRCT影像学改变，包括病变的数量、位置、分布、密度、形态以及间质性改变并加以分析。结果 NCP在一周内胸部HRCT图像上均有不同程度肺炎改变(3例4天后复查阳性表现)。23例（74.19%）病灶多发（3个及以上病变），24例（77.42%）累及两个及两个以上肺叶，7例（22.58%）病灶累及单肺叶。22例（70.97%）表现为多发磨玻璃样改变，9例（29.03%）多发磨玻璃改变并伴有混合性实变病灶，31例（100%）边界模糊。25例（80.65%）病变呈外周分布，6例（19.35%）外周分布合并局部中央分布病灶。26例（83.87%）病灶呈不规则斑片状，5例（16.13%）呈不规则斑片状伴有局部球形表现。26例（83.87%）伴有细支气管充气征，29例（93.55%）病变内血管增粗，24例（77.42%）有小叶内间隔增厚，6例（19.35%）伴有小叶间隔增厚。2例（6.45%）伴有小叶中心结节，1例（3.23%）伴有少许胸腔积液。结论 胸部HRCT是NCP重要检查方法，NCP早期胸部HRCT表现具有一定特征性，对NCP的早期诊断和鉴别诊断有重要的作用。 |

| Objective To explore the early features of patients with novel coronavirus pneumonia (NCP) on HRCT．Methods 31 cases with NCP were enrolled in this study and 34 chest HRCT examinations which were performed in 7 days of onset of symptoms(3 cases had a second scan four days later) were retrospectively analyzed and summarized．Results Positive abnormalities on chest HRCT scans were revealed in all 31 NCP cases. The main abnormalities on HRCT were pulmonary infiltrations.74.19% cases had 3 or more lesions. 77.42% cases affected more than two lobes with bilateral involvement.70.97% cases had multiple ground-glass opacities, 29.03% cases had multiple ground-glass opacities and mixed consolidation. All of the cases had fuzzy boundaries.80.65% cases presented a peripheral distribution.19.35% cases presented a peripheral distribution combined with central distribution.83.87% cases had irregular morphology,16.13% cases had rounded morphology.83.87% cases had air bronchogram. 93.55% cases had vascular thickening in the lesion. 77.42% cases had intralobular interstitial thickening.19.35% cases had interlobular interstitial thickening.6.45% cases had centrilobular nodules and 1case had a small amount of pleural effusion. Conclusion The early chest HRCT of NCP has certain characteristics and plays an important role in the early diagnosis and differential diagnosis of NCP． |
