【摘要】：目的研究飛利浦64排CT在顱腦CT血管成像(CTA)中射線輻射低劑量和低濃度對比劑的臨床應(yīng)用。方法將2015-05—2016-07在鄭州市中心醫(yī)院進(jìn)行頭部CT血管成像檢查(CTA)的57例患者隨機(jī)分為A、B組,A組給予普通常規(guī)掃描條件(管電壓100Kv,管電流100mA),造影劑(350mg/mL);B組使用低管電流掃描條件(管電壓100Kv,管電流80mA),造影劑(270mg/mL)。掃描后分別測量2組患者的雙側(cè)頸總動(dòng)脈起始部、雙側(cè)大腦中動(dòng)脈M1段、基底動(dòng)脈V2段的各個(gè)CT值結(jié)果。評價(jià)顱內(nèi)動(dòng)脈分支的顯示情況。結(jié)果 2組血管CT值差異均無統(tǒng)計(jì)學(xué)意義(P0.05)。2組顱內(nèi)動(dòng)脈分支CTA后處理3D所得的評分結(jié)果差異均無統(tǒng)計(jì)學(xué)意義(P0.05)。結(jié)論飛利浦64排機(jī)器掃描顱腦CTA使用低電壓和低濃度造影劑,可得到臨床影像診斷的圖像質(zhì)量,又可減少射線劑量,值得臨床推廣使用。
[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.
