摘要
目的:分析多层螺旋CT低剂量技术在肝癌患者腹部扫描中的应用价值。材料与方法:选取2013年02月~2015年02月本院收治的80例肝癌患者临床资料,随机分为观察组及对照组,各40例。对照组给予常规剂量螺旋CT扫描,观察组给予多层螺旋CT低剂量技术扫描,对比两组患者扫描结果。结果:观察组放射剂量为(3.32±0.68)m Sv明显低于对照组的(6.72±2.74)m Sv,差异有统计学意义(P〈0.05)。观察组CT图像质量评分、图像平扫、静脉期以及动脉期噪声值分别为(4.83±0.84)分、(10.67±0.34)、(12.03±1.33)、(12.76±1.46),与对照组的(4.86±0.83)分、(10.53±0.55)、(11.46±1.36)、(12.64±0.26)对比,差异无统计学意义(P〉0.05)。结论:在肝癌患者腹部扫描中应用多层螺旋CT低剂量技术,通过轴位扫描及自动毫安技术,有利于降低CT扫描的辐射剂量,确保较高的图像质量,值得临床推广。
Purpose: To analyze the low-dose multislice CT technology applications in liver cancer patients with ab- dominal scan. Materials and Methods: February 2013 - February 2015 our hospital clinical data 80 cases of liver cancer pa- tients were randomly divided into two groups and the control group, 40 cases. The control group received conventional-dose spiral CT scan, observe the group was given a low-dose muhislice CT scanning technology, comparing two groups of patients scan results. Results: The dose of radiation (3.32 ± 0. 68) mSv was significantly lower than the control group (6. 72±2. 74) mSv, the difference was statistically significant ( P 〈 0. 05 ). Observation group CT image quality score, unenhanced images, arterial venous phase and phase noise value was (4. 83 ±0. 84) points, ( 10. 67 ±0. 34 ) , ( 12. 03 ± 1.33 ) , (12.76 ± 1.46), and the eontrol group (4.86 ± 0.83) points, (10.53 ± 0.55), (11.46± 1.36), (12.64 ± 0.26) compared the difference was not statistically significant ( P 〉 0. 05 ). Conclusion: In patients with liver cancer in the abdo- men scan low-dose multislice CT technology, through axial scanning and automatic mA technology, help to reduce the radiation dose CT scan to ensure high image quality, worthy of promotion.
