摘　　要：目的:通过认识肺膨胀不全的胸部CT表现,加深对肺不张影像学征象的分析,有利于在肺部感染性疾病与少量胸腔积液的诊断与鉴别,有助于指导临床治疗方案的选择。方法:选择2017年9月~2020年4月住院期间在本院行胸部CT检查患者,对其肺部影像阴影分布、形态、密度表现识别及复查对比,并根据诊断结果将肺膨胀不全、少量胸腔积液影像表现归类和分析。结果:在150例肺膨胀不全患者中,胸腔积液合并肺膨胀不全患者83例,占比55.33%,新月实变影37例,占比24.67%,新月实变伴支气管充气征30例,占比20.00%。结论:胸部CT肺膨胀不全影像表现有特征性;少量胸腔积液合并肺膨胀不全是较典型多发的影像表现,熟悉掌握肺膨胀不全影像表现,可明确肺部有无炎症渗出,给予临床医生肯定答复,有利于临床医生对患者病情实际掌控及分析,对临床指导用药有较高价值,评估患者预后恢复效果。Objective:To understand the chest CT manifestations of atelectasis,deepen the analysis of the imaging signs of atelectasis,which is helpful to the diagnosis and differentiation of pulmonary infectious diseases and a small amount of pleural effusion,and to guide the choice of clinical treatment.Methods:Patients who underwent chest CT examination in our hospital from September 2017 to April 2020 were selected,and their lung shadow distribution,shape,density performance were identified and compared,and the imaging manifestations of pulmonary atelectasis and a small amount of pleural effusion were classified and analyzed according to the diagnosis results.Results:Among the 150 cases of pulmonary atelectasis,83 cases of pleural effusion combined with atelectasis,accounting for 55.33%,37 cases of crescent consolidation,accounting for 24.67%,30 cases of crescent consolidation with bronchial inflation sign,accounting for 20.00%.Conclusion:Chest CT pulmonary atelectasis imaging features are characteristic;a small amount of pleural effusion combined with pulmonary atelectasis is a more typical and multiple imaging manifestations,familiar with the imaging manifestations of pulmonary atelectasis can determine whether there is inflammatory exudation in the lung,and give the clinician a positive reply,which is conducive to the clinical doctors’actual control and analysis of the patient’s condition,and is of higher value for clinical guidance of medication,and to evaluate the effect of patients'prognosis recovery.
