Numerous respiratory disorders may be responsible for right heart dysfunction, frequently suboptimally assessed in routine clinical practice. Multidetector-row CT systems with fast scanning capabilities can acquire images of the thorax with reduced cardiac motion artifacts, enabling improved evaluation of the heart. Moreover, the introduction of fast rotation speed and dedicated cardiac reconstruction algorithms exploiting the multislice acquisition scheme of the data has opened the possibility of integrating right cardiac functional information into a diagnostic CT scan of the chest, without or with ECG gating.
许多呼吸系统疾病可能导致右心功能障碍，在常规临床实践中对此的评估往往不够理想。具有快速扫描能力的多排螺旋CT系统能够获取胸部图像，减少心脏运动伪影，从而改善对心脏的评估。此外，利用数据的多层采集方案引入快速旋转速度和专用心脏重建算法，使得在不使用或使用心电图门控的情况下，将右心功能信息整合到胸部诊断CT扫描中成为可能。
