目的探讨三维彩超在心脏放射性损伤方面的应用。方法 40例接受胸部放疗的肿瘤患者放疗前后常规超声心动图和三维彩超Tei指数的测定。结果常规超声心动图LADs、LVDd、EF在治疗前后无明显差别,E/A在放疗后明显减低(P<0.05),治疗前后三维彩超Tei指数显示治疗后比治疗前明显增高(P<0.05)。结论三维彩超Tei指数可评价胸部放疗早期心脏损伤。
Objective To investigate the application of three-dimensional ultrasound in cardiac radioactive injury. Methods The routine echocardiography and three-dimensional color Doppler ultrasound Tei index of 40 patients with thoracic radiotherapy were measured before and after radiotherapy. Results Before and after treatment, there was no significant difference in LADs, LVDd and EF between the two groups. E / A decreased significantly after radiotherapy (P <0.05). Before and after treatment, the Tei index of three - dimensional ultrasonography showed significantly higher than that before treatment (P <0.05) . Conclusion The three-dimensional color Doppler ultrasound Tei index can evaluate the early stage of chest radiotherapy.
