[CT features of right heart involvement in thoracic diseases].

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.
