摘要
目的探究第二代双源CT低剂量法全肝灌注在原发性肝癌的肝动脉化疗栓塞术(TACE)前后的血供情况。方法选取原发性肝癌并采用TACE术治疗的患者共32人,其中男性患者27人,女性患者5人,年龄31-76岁。两组患者分别采用k V值、m As值不同的扫描。术前7天及术后20天分别进行三期常规扫描和灌注扫描。把甲、乙组灌注扫描辐射剂量分别与肝脏常规三期扫描、水模扫描辐射剂量进行对比分析。结果两组患者栓塞术前后双源CT低剂量灌注扫描效果良好,获取了准确的扫描数据和清晰的容积图像。两组常规肝脏增强扫描与双源CT低剂量灌注扫描采用单样本t检验,甲:P<0.05;乙:P>0.05。乙组辐射剂较甲组低,相对于常规平扫加肝脏增强扫描需要的辐射剂量更为接近。结论第二代双源CT大幅度地降低了扫描的k V值、m As值,可以捕获较为清晰的肝脏低剂量灌注图像,并且第二代双源CT低剂量法全肝灌注在原发性肝癌的TACE术治疗前后的血供情况观察效果良好,值得临床广泛使用。
Objective To explore the second-generation dual-source CT low-dose whole liver perfusion method in the blood supply of primary liver cancer hepatic arterial chemoembolization （TACE） before and after. Methods Primary liver cancer and the use of TACE treatment of patients with a total of 32 people, including 27 males, 5 females, aged 31 to 76 years. Two groups of patients were using the kV, mAs values of different scans. Preoperative 7 days and 20 days respectively after three regular scans and perfusion scan. The A, B perfusion scan radiation doses were associated with liver conventional three scanning, water phantom scan radiation dose were analyzed. Results The two groups of patients before and after embolization of low-dose dual-source CT perfusion scan to good effect, to obtain an accurate scan data and a clear volumetric image. Two conventional liver enhanced scan and dual source CT perfusion scan using a single low-dose sample t-test, A： P 0.05. Group A Group B radiation agents representing low, relative to conventional plain and liver scan radiation dose required to enhance closer. Conclusion The second-generation dual-source CT significantly reduce the value kV, mAs value scanning, you can capture a clearer picture of liver low-dose infusion, and the second-generation dual-source CT low-dose whole liver perfusion method in primary liver cancer the TACE technique to observe the effect of the blood supply before and after treatment is good, worthy of widespread use.
