目的 探讨双源CT双能量扫描在 胰腺肿瘤诊断的临床应用价值。方法 选 取我院40例患者随机分为实验组和对照 组，分别进行双源CT常和规CT扫描，并 对检查结果进行评估，同时对患者所接 收的辐射剂量进行统计。结果 双源CT 成像结果较清晰，对于胰腺肿瘤相关性 疾病的检出率明显高于常规CT，而且患 者所接收的总辐射剂量、有效辐射剂量 也比常规CT明显降低，差异有统计学意 义。结论 双源CT具有成像效果良好，对 于疾病的检出率高，辐射剂量

Objective To investigate the value of dual-source CT scan in diagnosis of pancreatic cancer. Methods Forty patients enrolled in this study, were divided into experimental group and control group, randomly. The patients in the experimental group were detected with DSCT, and the ones in the control group were detected with nomal CT. And then, the results of the detection and the dose of the rays patients recived were collected and analyzed. Results The DSCT got more clearly imaging and high positive frequency than the control group, but also a lower total dose and effective dose of rays, the difference was statistically significant. Conclusion The DSCT had an advantage of clearly imaging, high positive frequency and lower dose of rays. It was deserved to be widely used in clinical.
