摘　　要：目的研究螺旋CT扫描应用于结核分枝杆菌肺病患者影像学特点和临床诊断价值。方法选取2021年10月—2023年2月本院结核分枝杆菌肺病患者155例作为本次研究对象,采用回顾性分析资料的方式进行研究。所有患者均进行螺旋CT扫描检查,并以病理学、细菌学以及纤维支气管镜诊断作为金标准,分析患者影像学特点、诊断价值。结果分析影像学特点,经螺旋CT扫描检查155例,显示存在斑片浸润征象、散播病灶、条索节结征象、胸膜增厚、多发空洞、肺不张、胸腔积液,其中斑片浸润征象(89.03%)、散播病灶(69.68%)、条索节结征象(63.23%)占比较高。分析诊断价值,经金标准检查出阳性120例,阴性35例。采用螺旋CT扫描后,检查出阳性117例,阴性32例。经螺旋CT扫描诊断,阳性检出率(77.42%)、灵敏度(97.50%)、特异度(91.43%)、阳性预测值(97.50%)、阴性预测值(91.43%),其与金标准对比,差异无统计学意义(P>0.05)。诊断符合率(96.13%)虽然与金标准对比,差异无统计学意义(P>0.05)。结论针对结核分枝杆菌肺病患者,实施螺旋CT扫描能够尽早较为精确诊断,诊断效果较高,可较为清晰观察影像学特点,具有重要参考价值,有利于为患者尽快制定治疗方案,在临床诊断方案中值得大力实施以及推广。Objective To study imaging characteristics and clinical diagnostic value of spiral CT scanning for patients with mycobacterium tuberculosis pulmonary disease.Methods The paper chose 155 patients with mycobacterium tuberculosis lung disease in our hospital from October 2021 to February 2023 as study subjects,carried on spiral CT scans based on retrospective analysis of data,and analyze imaging characteristics and diagnostic value of patients with gold standards of pathology,bacteriology,and fiberoptic bronchoscopy.Results Imaging characteristicsanalysis showed,155 cases had presence of patchy infiltration signs,scattered lesions,cord and node signs,pleural thickening,multiple cavities,atelectasis,and pleural effusion based on examination of spiral CT scanning.Among them,patchy infiltration signs(89.03%),scattered lesions(69.68%),and cord and node signs(63.23%)accounted for relatively high proportion.Diagnostic value analysis showed,120 cases were positive and 35 cases were negative according to the gold standard examination.Based on spiral CT scanning,117 cases were positive and 32 cases were negative.After spiral CT scanning diagnosis,the positive detection rate(77.42%),sensitivity(97.50%),specificity(91.43%),positive predictive value(97.50%),and negative predictive value(91.43%)were detected.There was no significant difference from the gold standard(P>0.05).Diagnostic compliance rate(96.13%)was relatively low,there was difference from the gold standard.Conclusion Spiral CT scanning can provide early and accurate diagnosis for patients with mycobacterium tuberculosis pulmonary disease,with high diagnostic effect,important reference value and clear observation of imaging characteristics,which is conducive to developing treatment plans for patients as soon as possible,and worthy of great application and promotion in clinical diagnosis schemes.
