胸部低剂量CT扫描在肺结节鉴别诊断中的应用

Application of Low-dose Chest CT Scan in Differential Diagnosis of Pulmonary Nodules

目的 探讨胸部低剂量CT扫描在肺结节鉴别诊断中的应用。方法 选取2018年1月至2018年12月在我院接受肺结节治疗的74例患者作为本研究对象,依据不同的扫描方式分为常规剂量组(对照组)与低剂量组(研究组)。对照组采用常规剂量扫描,研究组采用胸部低剂量CT扫描。比较两组对肺结节的检出率情况以及辐射剂量、肺结节扫描直径测量。结果 两组对肺结节的空洞、毛刺、钙化、所属或邻近支气管的情况、分叶以及胸膜粘连等特征的检出率均无显著差异(P>0.05);研究组辐射剂量低于对照组(P<0.05),两组肺结节扫描直径测量值无显著差异(P>0.05)。结论 对肺结节患者在进行临床随诊期间,采用胸部低剂量CT扫描其诊断结果 与常规剂量扫描相当,且对患者X线辐射剂量明显降低,对患者身体影响相对较小,具有较高的安全性,促使患者在心理、精神上的压力显著降低,其接受度和依从性明显升高,利于临床应用及推广。

Objective to investigate the application of low-dose chest CT scan in the differential diagnosis of pulmonary nodules.Methods 74 patients who received treatment for pulmonary nodules in our hospital from Janua ry 2018 to December 2018 were selected as the su bjects of this study.According to different diagnostic methods,they were divided into conventional dose group(control group) and low-dose group(research group).The control group received routine dose sca n,while the study group received low-dose CT scan of the chest.The detection rate,radiation dose and scanning diameter of pulmonary nodules were compared between the two groups.Results there was no significant difference in the detection rate of cavity,burr,calcification,bronchial status,lobulation and pleural adhesion between the two groups(P>0.05).The radiation dose in the study group was lower than that in the control group(P<0.05),and there was no significant difference in the scanning diameter of pulmonary nodules between the two groups(P>0.05).Conclusion during the clinical diagnosis of patients with pulmonary nodules,low-dose CT scan of the chest has the same diagnosis results as conventional dose scan,and significantly lower X-ray radiation dose to patients,and has a relatively small impact on the patient’s body,with a high safety,prompting patients in psychological and mental pressure decreased significantly,its acceptance and compliance increased significantly,which is conducive to clinical application and promotion.
