【摘要】：目的探討64層螺旋CT胸痛三聯(lián)癥低劑量成像的臨床應(yīng)用價(jià)值。方法以我院放射科收治的因急性胸痛就診并擬行胸痛三聯(lián)掃描的108例患者為研究對(duì)象,所有患者根據(jù)體質(zhì)量指數(shù)(BMI)不同選擇管電壓,若BMI≥24kg/m2,管電壓為120Kv;若BMI24kg/m2,管電壓為100Kv。將其為A組、B組,A組為BMI24kg/m2(58例),采用前瞻性心電門控技術(shù)掃描;B組為BMI≥24kg/m2(50例),采用回顧性心電門控技術(shù)掃描,分析64層螺旋CT胸痛三聯(lián)癥低劑量成像的臨床應(yīng)用價(jià)值。結(jié)果 A組患者圖像質(zhì)量與B組相比,無顯著差異(P0.05);A組受限劑量與B組相比,存在顯著差異,P0.05。結(jié)論64層螺旋CT胸痛三聯(lián)癥低劑量成像的臨床應(yīng)用價(jià)值高,圖像質(zhì)量可靠,患者承受的輻射劑量少,具有較高的臨床應(yīng)用價(jià)值,值得推廣。
