64排螺旋CT腹部血管成像低剂量扫描效果

Effect of Low-dose Scan of 64-slice Spiral CT Abdominal Angiography

目的以胰腺癌患者为研究对象,分析64 排螺旋CT 腹部血管成像低剂量扫描的可行性及对图像质量的影响,以供参考应用。方法选择2016 年7 月—2018 年11 月我院收治的胰腺癌患者为研究对象,共82 例,所有患者均给予64 排螺旋CT,根据对比剂的不同剂量给予低剂量及常规剂量扫描,每组均为41 例。观察腹部血管成像变化,并分析对比不同扫描条件下图像质量及诊断价值。结果低剂量扫描与常规剂量扫描的图像质量对比,P > 0.05;低剂量与常规剂量扫描对胰腺癌血管侵犯诊断准确性及灵敏度等差异无统计学意义,P > 0.05。结论使用64 排螺旋CT 进行腹部血管成像低剂量扫描具有较高的应用价值,可以保证图像质量,诊断价值较高。

Objective To analyze the feasibility of low-dose abdominal angiography with 64-slice spiral CT in patients with pancreatic cancer and its effect on image quality for reference. Methods 82 patients with pancreatic cancer admitted to our hospital from July 2016 to November 2018 were selected as the study subjects. All patients were given 64-slice spiral CT. According to the different doses of contrast agent, 41 patients were given low-dose and routine-dose scanning, each group was 41 cases. Observe the changes of abdominal angiography, and compare the image quality and diagnostic value under different scanning conditions. Results The image quality of low dose scan was better than that of routine dose scan (p > 0.05), and there was no significant difference between low dose scan and routine dose scan in the accuracy and sensitivity of diagnosis of vascular invasion of pancreatic cancer (P > 0.05). Conclusion Low-dose abdominal angiography with 64-slice spiral CT has high application value, which can ensure image quality and diagnostic value.
