【摘要】：目的研究飞利浦64排CT在颅脑CT血管成像(CTA)中射线辐射低剂量和低浓度对比剂的临床应用。方法将2015-05—2016-07在郑州市中心医院进行头部CT血管成像检查(CTA)的57例患者随机分为A、B组,A组给予普通常规扫描条件(管电压100Kv,管电流100mA),造影剂(350mg/mL);B组使用低管电流扫描条件(管电压100Kv,管电流80mA),造影剂(270mg/mL)。扫描后分别测量2组患者的双侧颈总动脉起始部、双侧大脑中动脉M1段、基底动脉V2段的各个CT值结果。评价颅内动脉分支的显示情况。结果 2组血管CT值差异均无统计学意义(P0.05)。2组颅内动脉分支CTA后处理3D所得的评分结果差异均无统计学意义(P0.05)。结论飞利浦64排机器扫描颅脑CTA使用低电压和低浓度造影剂,可得到临床影像诊断的图像质量,又可减少射线剂量,值得临床推广使用。
[Abstract]:Objective to study the application of Philips 64-slice CT in craniocerebral CT angiography (CTAs). The clinical application of low dose and low concentration contrast agent of moderate radiation radiation. Methods CT angiography of head was performed in Zhengzhou Central Hospital from 2015 to 2016-07. A total of 57 patients were randomly divided into A. Group A was given conventional scanning conditions (tube voltage 100kv, tube current 100mAV, contrast agent 350 mg / mL); In group B, low-tube current scanning conditions (tube voltage 100kv, tube current 80mAn, contrast agent 270mg / mL) were used to measure the bilateral common carotid artery origin after scanning. M1 segment of bilateral middle cerebral artery. Ct results of V2 segment of basilar artery. Evaluation of the display of intracranial artery branches. Results there was no significant difference in CT value between the two groups (P 0.05). There was no significant difference in the scores of 3D after CTA treatment of intracranial artery branches in group 2 (P 0.05). Conclusion Philips 64 row machine scan brain CTA uses low voltage and low concentration contrast medium. The image quality of clinical imaging diagnosis can be obtained, and the radiation dose can be reduced, so it is worth popularizing in clinic.
