多排螺旋CT多期扫描在胰腺癌诊断中的价值

Determination of the Residual Quantity of Cyclohexanone in Disposable Pressure Transducer and the Analysis of the Sampling Method

目的:探究在胰腺癌诊断中多排螺旋CT多期扫描的价值。方法:对我院2014年2月到2016年3月间接收的40例胰腺癌患者采用多排螺旋CT多期扫描进行诊断,同时和实验室检验结果进行对比,观察多排螺旋CT多期扫描诊断的准确性。结果:经过对多排螺旋CT扫描结果进行分析,发现CT扫描患者的肿瘤大小有39例患者和实验室检查结果相吻合,肿瘤大小的诊断准确率为97.5%;对患者的肿瘤分期进行诊断,CT扫描有31患者和实验室检查结果相吻合,准确率为77.5%。结论:多排螺旋CT多期扫描在胰腺癌诊断中对于肿瘤的位置、形态、大小、密度及周围结构的诊断较为准确,同时可以提供一定的分期情况,指导临床进行及早后期干预和治疗,从而改善胰腺癌患者预后,延长患者生命,在临床中具有较为重要的价值,值得我们进行借鉴。

Objective: To establish a method for determination the residual quantity of Cyclohexanone in Disposable Pressure Transducer, and analysis the results for different sampling method. Methods: Determination in GC. Sampling method is as follows:(1) extracted by a circular pump;(2) Limit extraction. Results: The correlation coefficient of the linear equation were 0.996 and 0.998; the average recovery rate was 101%(n=9). Conclusion: the method is simple, rapid and accurate, the different sampling methods can be used to control the quality of different purpose.
