【摘要】：目的:分析在成人头颅检查中64排螺旋CT低剂量扫描技术的应用效果。方法:选取本院2016年3月—2017年4月期间接收的52例颅脑所描患者为探究对象,将这些患者按照双盲、随机方式,分为对照组与观察组。两组患者均应用降低球管mAs方式,将正常剂量扫描作为对照组,将低剂量扫描最为观察组,对两组患者的具体应用成效进行观察与对比。结果:观察组患者扫描图像的质量比对照组稍微低一点,可解剖细部结构和图像信息都满足诊断标准。两组患者的图像质量评价标准无明显的差距,无统计学意义(P0.05)另外,观察组的吸收剂量指数为33.56mGy,对照组的吸收剂量指数为59.66mGy,两组数据进行对比,对照组明显高于观察组,存在明显的差异性,有统计学意义(P0.05)。结论:在对成人颅脑进行检查时,应用64排螺旋CT低剂量扫描技术的诊断成效十分明显,使辐射剂量有效减少,并降低辐射的损害程度,保证了扫描图像的质量,并降低不良事故的发生率,值得广泛采纳与推广。
[Abstract]:Objective: to analyze the application effect of 64-slice spiral CT low-dose scanning technique in adult head examination. Methods: 52 patients with craniocerebral drawing received from March 2016 to April 2017 were divided into two groups: control group and observation group. Patients in both groups were treated with reduced balloon mAs, normal dose scan as control group and low dose scanning as observation group. The specific application results of two groups were observed and compared. Results: the quality of scanning images in the observation group was slightly lower than that in the control group. The anatomical details and image information met the diagnostic criteria. There was no significant difference in image quality between the two groups (P0.05). In addition, the absorption dose index of the observation group was 33.56 mGy, and the absorption dose index of the control group was 59.66 mGy. Compared with the two groups, the control group was significantly higher than the observation group. There are obvious differences, there is statistical significance (P0.05). Conclusion: in the examination of adult brain, the diagnosis effect of 64-row spiral CT low dose scanning technique is very obvious, the radiation dose is reduced effectively, the degree of radiation damage is reduced, and the quality of scanning image is guaranteed. And reduce the incidence of adverse accidents, worthy of extensive adoption and promotion.
