摘要:
目的：探讨320排螺旋CT不同时相选择方式在冠状动脉综合征诊断中的价值。方法：选择2024年6月至2025年4月在四川省中西医结合医院行CT检查的161例冠状动脉综合征患者，分别运用人工选择时相与ePhase自动选择时相进行图像重建。对比两种时相选择方式下主动脉根部各项参数值以及冠状动脉各分支血管评分。结果：ePhase自动选择时相组较人工选择时相组主动脉根部噪声值降低（P<0.05），信噪比、右冠状动脉评分、左冠状动脉主干评分、左前降支评分、左回旋支评分升高（P<0.05）。结论：在320排螺旋CT检查冠状动脉综合征患者的过程中，ePhase自动时相选择重建显著优化图像质量，有助于提升诊断效率。
Abstract:
Abstract: Objective To investigate the value of different phase selection of 320-row spiral CT in the diagnosis of coronary syndrome. Methods A total of 161 patients with coronary syndrome who underwent CT examination at Sichuan Integrative Medicine Hospital from June 2024 to April 2025 were enrolled. Image reconstruction was performed using the manual phase selection and the ePhase automatic phase selection, separately. The parameters of aortic root and the scores of coronary artery branches were compared between the two phase selection strategies. Results Compared with the manual phase selection group, the ePhase automatic phase selection group exhibited a reduced noise value at the aortic root (P<0.05), increased signal-to-noise ratio, and superior scores of the right coronary artery, left main coronary artery, left anterior descending branch, and left circumflex branch (P<0.05). Conclusion During the 320-row spiral CT examination of patients with coronary syndrome, the ePhase automatic phase selection significantly optimizes image quality and improves diagnostic efficiency.
