MDCT偵測冠狀動脈血管與傳統心導管比較
16 Slice CTA of Coronary Artery Compared with Conventional Angiography
摘要
本研究的目的是利用多切面電腦斷層偵測冠狀動脈血管，將其結果與傳統心導管檢查結果作統計分析與比較。方法上，共有42位由心臟內科部醫師判定患有心血管疾病患者，同意進行多切面電腦斷層檢查。注射51 ml NaCl和80 ml的對比劑，球管旋轉一次0.37秒，掃瞄時間19秒，重組切面厚度為0.75 mm。CTA血管狹窄評估以50%為標準，分為小於50%及大於50%，再與傳統心導管比較。結果發現：心導管檢查對於小於百分之50的狹窄常忽略或無法辨識，然而這些病灶在電腦斷層上卻相當的明顯。因此，造成在百分之50以上或百分之50以下兩區間內，電腦斷層血管攝影發現病灶數皆較心導管為多。

The research main goal is uses multi-detector computer tomography (MDCT) to appraise the coronary artery plaque degree. The result (CATH) inspects the discovery with the traditional cardiac catheterization to make the statistics again to compare. Materials: The, total 42 suspicions has the heart blood vessel disease examining, accepts the MDCT inspection by the heart internal medicine department transfer. Injects 51 ml NaCl and 80 ml contrast material; Tube rotational speed 0.37 sec/Rot; Scanning time 19 sec; Reorganization thickness 0.75 mm. The coronary artery narrow degree take 50 % as the appraisal standard, divides into ＜50% and ＞50%, appraised the result does again with the cardiac CATH inspection compares. The study find: CATH inspection regarding is smaller than 50% narrow frequently neglects or is unable to debate the knowledge, however these sickness stoves quite are actually obvious in CTA. CTA is narrow regarding 50% about frequently excessively appraised. Wherefore, above two reasons are create above 50% or in 50% below two sectors, CTA discovered sickness stove number compares CATH is many main reasons.
