Gemstone Spectral CT High Resolution Mode Imaging in Improving Coronary Stent Display Value
Objective To investigate the value of Gemstone spectral CT high resolution reconstruction mode imaging in improving coronary stent display.Methods Twenty-eight patients who underwent CT reexamination after coronary stenting were selected as the observation objects.After coronary CTA scanning with gemstone spectral CT,high-resolution mode reconstruction and standard mode reconstruction were performed respectively on the original data of all patients to observe the display ability of stent lumen and stent wall.Results The subjective assessment of coronary stent imaging quality in the high-resolution mode reconstruction group demonstrated superior performance compared to the standard reconstruction group.This difference was found to be statistically significant(P＜0.05).The coronary stent diameter and stent lumen display rate in the high resolution mode reconstruction group were better than those in the standard reconstruction group,and the increase of CT value in the stent was significantly lower than that in the conventional scanning group,and the differences were statistically significant(P＜0.05).Conclusion Gemstone spectral CT high-resolution reconstruction mode can clearly display the characteristics of the stent,can significantly improve the imaging quality of coronary stent,and has good clinical application value.
