慢性阻塞性肺疾病右心室功能影像学研究新进展

右心室功能的准确评估对慢性阻塞性肺疾病（COPD）的临床诊断及治疗至关重要。鉴于右心室几何形状复杂，传统影像检查方法对于其功能评价的准确性受到制约。近年来随着超声心动图组织多普勒成像(TDI)及应变率成像（SRI）技术的临床应用，多层螺旋ＣＴ时间分辨率提高及对比剂注射方案的优化，CMRI电影及相位对比技术的发展，放射性核素的各种新技术在心脏形态和功能评价中取得突破，使得影像技术客观、准确、定量地评估COPD病人右心室功能成为可能。

New developments in imaging methods to assess right ventricular function in chronic obstructive pulmonary disease

Accurate assessment of right ventricular function in chronic obstructive pulmonary disease (COPD) is essential for the clinical diagnosis and treatment. Given the complex right ventricular geometry, the traditional imaging modalities are difficult to precisely evaluating its function. With recent development in the echocardiographic tissue doppler imaging (TDI) and strain rate imaging (SRI), optimization in the temporal resolution of multislice CT and contrast medium injection scheme, the advancement of CMRI cine phase-contrast, as well as all kinds of new radionuclide techniques, it makes a breakthrough in evaluation of cardiac morphology and function. The imaging technology become much objective, accurate, quantitative in evaluation of right ventricular function in COPD patients.
