Abstract: Objective:To explore the clinical application value of "Magic Glass" function in coronary CTA. Methods:A retrospective analysis of 50 hospital cases of coronary CTA was used to evaluate the value of "Magic Glass" function application in the coronary plaque, luminal conditions and assessment of coronary stent. Results:All 50 cases of coronary CTA images can be used for diagnosis. After application of "Magic Glass" function, 595 calcified plaque, 1290 mixed plaque, 126 non-calcified plaque was found; and lumen of 729 CA segments was clearly showed; stenosis 75%, 146 segments, 50%~75%, 209 segments, 25%~50%, 108 segments, 25%, 266 segments. 11 of 29 implanted stents, lumen formation of soft plaque, stenosis 5, 6 plaque formation before and after stent, causing stenosis 4. Conclusion:The application of "Magic Glass" function in coronary CTA reconstruction can clearly display and evaluation of coronary artery plaque, coronary stent lumen conditions, and does not affect the outside organization of "Magic Glass".
