早期中心型肺癌的多排螺旋CT诊断价值分析

Value analysis of multi-slice spiral CT diagnosis of early central lung cancer

目的分析多排螺旋CT在早期中心型肺癌中的诊断价值.方法选取36例接受早期中心型肺癌诊治的患者作为研究对象,患者均经手术病理以及纤维支气管镜检查确诊,患者均实施多排螺旋CT检查,分析患者的多排螺旋CT影像学表现,比较多排螺旋CT与手术病理诊断结果(支气管壁异常、支气管腔异常以及肺气肿合并肺炎的检出情况).结果CT影像显示36例患者支气管腔内均可见肿瘤且支气管壁显著增厚,4例(11.11%)患者支气管远端可见黏液栓塞,病灶周围存在明显肿大的肺门淋巴结以及淋巴结肿大现象;14例(38.89%)患者可见明显的支气管腔狭窄以及阻塞等表现.多排螺旋CT对支气管壁异常、支气管腔异常以及肺气肿合并肺炎的检出率分别为77.78%、91.67%、47.22%,均略低于手术病理的83.33%、88.89%、52.78%,但比较差异无统计学意义(P>0.05).结论多排螺旋CT具有无创、检测速度快、分辨率高等特点,患者耐受度以及接受度均较高,在早期中心型肺癌诊断中具有较高的应用价值,能够准确检出肺炎合并肺气肿、支气管腔异常以及支气管壁异常,有助于临床医生及早采取病情控制措施以促进患者预后改善.

Objective To analyze the value of multi-slice spiral CT diagnosis of early central lung cancer.Methods A total of 36 patients with early central lung cancer were selected as the research subjects,and all patients were confirmed by operation pathology and fiberbronchoscopy.All patients were examined by multi-slice spiral CT,and their imaging manifestations of multi-slice spiral CT were analyzed.The results of multi-slice spiral CT and operation pathology were compared(detection of bronchi wall abnormality,bronchi cavity abnormality and emphysema with pneumonia).Results CT images showed that 36 patients had tumors in the lumen of the bronchi and the wall of the bronchi was significantly thickened,4 patients(11.11%)had mucus embolism at the distal end of the bronchi,there were obviously enlarged hilar lymph nodes and lymph nodes around the lesions,14 patients(38.89%)had obvious stenosis and obstruction of the bronchi.The detection rate of multi-slice spiral CT for bronchial wall abnormality,bronchial cavity abnormality and emphysema with pneumonia were 77.78%,91.67%and 47.22%,respectively,which were slightly lower than 83.33%,88.89% and 52.78% of the operation pathology,but the difference was not statistically significant difference(P>0.05).Conclusion Multi-slice spiral CT has the characteristics of noninvasive,rapid detection,high resolution with high patient tolerance and acceptability.It has high application value in the diagnosis of early central lung cancer,and it can accurately detect pneumonia with emphysema,bronchial wall abnormality,bronchial cavity abnormality,which is helpful for clinicians to take disease control measures as early as possible to improve the prognosis of patients.
