通过对比分析常规剂量和低剂量MSCT扫描对颈部淋巴结结核的检出率,探讨低剂量MSCT在颈部淋巴结结核诊断中的临床应用价值。采集2014年1月至2016年1月,杭州市红十字会医院临床怀疑颈部淋巴结结核患者100例,随机分为常规剂量组和低剂量组,每组50例,分别行颈部MSCT常规剂量(120kV,200mA)或低剂量(120kV,100mA)平扫及增强扫描,对比分析两种扫描方案对颈部淋巴结结核检出率及扫描剂量的差异,并对颈部淋巴结结核MSCT征象与病理结果进行对照研究。结果显示,采用常规剂量和低剂量MSCT扫描对颈部淋巴结结核检出率差异无统计学意义(P>0.05),低剂量扫描的X线辐射剂量平均(1.46±0.14)mSv,低于常规扫描(2.73±0.33)mSv,差异有统计学意义(P<0.05)。低剂量与常规剂量MSCT扫描对颈部淋巴结结核检出及显示具有相同价值,但辐射剂量大幅降低,适用于颈部淋巴结结核的诊断与鉴别诊断,有助于减少患者辐射伤害。
The clinical value of low dose MSCT in the diagnosis of cervical lymph node tuberculosis was studied by comparing the detection rate of conventional and low dose MSCT to cervical lymph node tuberculosis. From January 2014 to January 2016, 100 patients with suspected cervical lymph node tuberculosis in Hangzhou Red Cross Hospital were randomly divided into routine dose group and low dose group, 50 patients in each group. The patients were divided into two groups: conventional MSCT (120kV, 200mA) or low dose (120kV, 100mA) plain scan and enhanced scan were compared between the two scan programs on the detection rate of cervical lymph node and scan the difference between the dose and neck lymph node tuberculosis MSCT signs and pathological findings Control study. The results showed that there was no significant difference in the detection rate of cervical lymph node tuberculosis between conventional and low-dose MSCT (P> 0.05), low-dose X-ray radiation (1.46 ± 0.14) mSv, (2.73 ± 0.33) mSv, the difference was statistically significant (P <0.05). Low-dose and conventional dose MSCT scan of cervical lymph node tuberculosis detected and showed the same value, but significantly reduced radiation dose for cervical lymph node tuberculosis diagnosis and differential diagnosis, help to reduce radiation injury in patients.
