为探讨严重急性呼吸综合征(SARS)X线胸片的演变规律,回顾性分析54例临床确诊的SARS病人的胸片,观测不同时期病变的位置、形态、数量、面积及密度的动态变化。结果在首次胸片上,54例中单侧受累33例,其中5例在随访中胸片转变为双侧受累双侧受累者21例,以下肺野(64.82%)和肺中带(94.44%)多见。病变形态演变具有3种模式,以斑片状片絮状局部肺纹理增粗完全吸收模式(64.82%)多见。病变数量演变包含5种模式,以单片型(40.74%)多见。病变面积演变包括单峰型(79.63%)、双峰型(12.96%)和持续恶化型(7.41%)。病变密度演变包括单峰型(57.69%)、双峰型(29.49%)、三峰型(7.69%)和持续恶化型(5.13%)。病程和病变占整个肺野最大比例在病变形态、数量、面积和密度的不同演变类型间均存在显著性差异。提示SARS病人胸片的演变具有一定规律,演变模式对患者预后具有提示作用。
To investigate the evolution of X-ray of severe acute respiratory syndrome (SARS), we retrospectively analyzed the chest radiographs of 54 clinically confirmed cases of SARS and observed the dynamic changes in the location, morphology, number, area and density of the lesions at different stages. Results In the first chest radiograph, 33 cases were unilateral in 54 cases. Among them, 5 cases were followed up with 21 cases involving both sides involved in bilateral involvement. The following fields (64.82%) and middle lung (94.44% More common. Three morphological changes of the lesion pattern were observed, and patchy patchy local lung texture thickening complete absorption pattern (64.82%) was more common. The number of lesions evolved contains 5 kinds of patterns to monolithic (40.74%) more common. Lesion area evolution including unimodal (79.63%), bimodal (12.96%) and persistent deterioration (7.41%). Lesions density evolution including unimodal (57.69%), bimodal (29.49%), three peaks (7.69%) and persistent deterioration (5.13%). The largest proportion of pathological and pathological changes in the entire lung field showed significant differences in different types of lesions, morphology, number, area and density. It is suggested that the evolution of chest X-ray in patients with SARS has certain rules, and the evolving pattern has a prompting effect on the prognosis of patients.
