【摘要】：目的探討64排螺旋CT橫截面圖像分析技術(shù)在冠狀動脈(冠脈)粥樣斑塊診斷中的價(jià)值。方法選取行64排螺旋CT檢查的患者65例,掃描后用心功能后處理軟件計(jì)算收縮左心室末期容積(ESV)、舒張末期容積(EDV)、射血分?jǐn)?shù)(EF)、每分輸出量、左心室收縮力;用橫截面圖像分析技術(shù)記錄動脈粥樣斑塊的位置、性質(zhì);根據(jù)美國放射學(xué)會的方法評價(jià)血管狹窄程度,并比較不同血管狹窄程度患者的左心功能。結(jié)果 65例患者共發(fā)現(xiàn)181個冠脈粥樣斑塊,冠脈左前降支近中段斑塊(55.25%)多于其他分支,斑塊多附著于血管的右側(cè)壁,占據(jù)兩個象限的斑塊較多,以右上象限和右下象限為主;鈣化性斑塊占85.25%。根據(jù)血管狹窄程度將患者分為輕度組、中度組和重度組,各組左心室EDV、ESV和EF比較差異有統(tǒng)計(jì)學(xué)意義(P均0.05)。結(jié)論通過64排螺旋CT橫截面圖像分析技術(shù)可很好地觀察冠脈粥樣斑塊位置及性質(zhì),并可根據(jù)血管狹窄程度評價(jià)左心功能。
[Abstract]:Objective to investigate the value of 64-slice spiral CT cross-sectional image analysis in the diagnosis of coronary atherosclerotic plaque. Methods Sixty-five patients with 64-row spiral CT were selected. The left ventricular end-diastolic volume (ESV),) end-diastolic volume (EDV),) ejection fraction (EF),) and the left ventricular systolic force (LVT) were calculated by the software of functional post-processing after scanning. The left ventricular end-diastolic volume (EDV),) ejection fraction (EF),) was calculated. The location and nature of atherosclerotic plaques were recorded by cross-sectional image analysis, and the degree of stenosis was evaluated according to the American Society of Radiology, and the left ventricular function of patients with different degree of stenosis was compared. Results A total of 181 atherosclerotic plaques were found in 65 patients. The number of plaques in the proximal middle segment of the left anterior descending coronary artery (55.25%) was more than that in the other branches. Most of the plaques attached to the right wall of the vessel and occupied more of the two quadrants. Mainly in the upper right quadrant and the lower right quadrant; Calcified plaques accounted for 85.25%. According to the degree of vascular stenosis, the patients were divided into three groups: mild group, moderate group and severe group. There were significant differences in left ventricular EDV,ESV and EF in each group (all P 0. 05). Conclusion the location and character of coronary atherosclerotic plaques can be observed well by 64-slice spiral CT cross-sectional image analysis, and the left ventricular function can be evaluated according to the degree of stenosis.
