摘要
目的探析宝石能谱CT评估冠状动脉介入治疗术后支架内成像质量的价值。方法方便选取该院心血管内科2019年5月—2020年5月收治的72例冠状动脉介入治疗术后患者,对其进行宝石能谱CT检查,根据不同扫描方式将其分为高分辨组与常规组,每组36例,高分辨组行高分辨扫描,常规组行常规扫描,对比两组的冠脉支架内成像质量评分;以冠状动脉造影检查结果为金标准,评价宝石能谱CT对冠状动脉再狭窄的评估价值。结果高分辨组的冠脉支架内成像质量评分、支架内径、支架内CT值、噪声值、对比噪声比[(4.65±0.52)分、(2.04±0.10)mm、(276.31±14.23)HU、(8.95±2.87)db、(24.65±13.72)]均优于常规组[(3.71±0.44)分、(1.74±0.07)mm、(382.65±12.08)HU、(6.91±2.27)db、(57.94±22.38)],差异有统计学意义(t=8.280、14.746、34.182、3.345、7.609,P<0.05);以冠状动脉造影评估结果为金标准,宝石能谱CT对冠状动脉再狭窄评估的符合率为91.77%,经计算,其敏感度、特异度、阳性预测值与阴性预测值分别为85.71%、94.83%、80.00%、96.49%。结论宝石能谱CT评估冠状动脉介入治疗术后支架内成像质量的价值高,对术后冠状动脉再狭窄评估的敏感度与特异度高,值得临床应用与推广。
Objective To explore the value of Gemstone CT in evaluating the quality of in-stent imaging after coronary interventional therapy.Methods Convenient select 72 patients after coronary interventional therapy in the Department of Cardiovascular Medicine of our hospital from May 2019 to May 2020,and perform gem energy spectrum CT examination on them.According to different scanning methods,they were divided into high-resolution group and the conventional group,36 cases in each group,the high-resolution group underwent high-resolution scanning,the conventional group underwent conventional scanning,and the coronary stent imaging quality scores of the two groups were compared;the coronary angiography examination results were used as the gold standard to evaluate the gem energy spectrum CT The evaluation value of coronary artery restenosis.Results The coronary stent imaging quality score,stent inner diameter,CT value in stent,noise value,contrast-to-noise ratio[(4.65±0.52)points,(2.04±0.10)mm,(276.31±14.23)HU,(8.95±2.87)db,(24.65±13.72)]in the high-resolution group were better than the conventional group[(3.71±0.44)points,(1.74±0.07)mm,(382.65±12.08)HU,(6.911±2.27)db,(57.94±22.38)],the difference was statistically significant(t=8.280,14.746,34.182,3.345,7.609,P<0.05);taking the coronary angiography assessment result as the gold standard,the coincidence rate of Gem Energy Spectrum CT for the assessment of coronary artery restenosis was 91.77%.After calculation,its sensitivity,specificity,positive predictive value and negative predicted values were 85.71%,94.83%,80.00%,96.49%,respectively.Conclusion Gemstone spectrum CT has high value in evaluating the quality of in-stent imaging after coronary interventional therapy,and it has high sensitivity and specificity in evaluating postoperative coronary artery restenosis.It is worthy of clinical application and promotion.
