【摘要】目的 观察多层螺旋CT在不典型肺结核诊断中的应用效果。方法 随机抽选本院接收的100例不典型肺结核患者,时间选自2019年5月-2020年5月,均接受多层螺旋CT检查,对诊断结果进行分析。结果 诊断准确率方面,CT检查是95.00%,病理检查是100.00%,CT检查较病理检查偏低,差异明显(P<0.05);经CT检查确诊的95例患者中,肺部实变、肿块或者结节、空洞型、阻塞性肺炎、纵膈淋巴结结核分别有17例、34例、20例、7例、17例,占比分别是17.89%、35.79%、21.05%、7.37%、17.89%。结论 不典型肺结核影像学表现有很多,经过多层螺旋CT检查可以明确病灶类型,但是在诊断准确率方面具有一定不足,需要与其他诊断方法结合在一起,从而促进诊断准确率的提高。

【Abstract】Objective To observe the application effect of multi-slice spiral CT in the diagnosis of atypical tuberculosis. Methods A random selection of 100 patients with atypical tuberculosis in our hospital were selected from May 2019 to May 2020. All of them underwent multi-slice spiral CT examination and the diagnosis results were analyzed. Results In terms of diagnostic accuracy, CT examination was 95.00%, pathological examination was 100.00%, CT examination was lower than pathological examination, and the difference was significant (P<0.05); among 95 patients diagnosed by CT examination, lung consolidation and mass Or nodules, cavities, obstructive pneumonia, and mediastinal lymph node tuberculosis have 17 cases, 34 cases, 20 cases, 7 cases, and 17 cases respectively, accounting for 17.89%, 35.79%, 21.05%, 7.37%, and 17.89% respectively . Conclusion There are many imaging manifestations of atypical pulmonary tuberculosis. Multi-slice spiral CT can clarify the type of lesion, but it has certain shortcomings in the diagnostic accuracy. It needs to be combined with other diagnostic methods to improve the diagnostic accuracy. [Keywords] atypical; tuberculosis; multi-slice spiral CT
近年,因为艾滋病、糖尿病、免疫系统疾病等患病人数越来越多,再加之抗生素使用不合理,导致不典型肺结核患者逐渐增多,并呈上升趋势。相比于常规的肺结核疾病,其在病变位置、临床表现及影像学表现方面与之存在明显差异,所以,临床诊治难度较大。现阶段,主要通过痰细菌学检查方法诊断普通肺结核,但是经调查研究发现,许多活动性肺结核患者经过痰细菌检查提示音信。据有关资料显示[1],临床上25%左右的活动性肺结核患者伴有轻微症状或者未见明显症状。针对该病的诊断,主要根据医生临床经验及X线平片检查进行诊断,但是具有较高的误诊率。为提高不典型肺结核诊断准确率,因而本次研究主要针对本院2019年5月-2020年5月接收的不典型肺结核患者采取多层螺旋CT检查效果进行综合分析,详情如下。……
