Combined Electrocardiography- and Respiratory-Triggered CT of the Lung to Reduce Respiratory Misregistration Artifacts between Imaging Slabs in Free-Breathing Children: Initial Experience

posted by Hyun Woo Goo, M.D. | Dec 7, 2017
Hyun Woo Goo, M.D.

Cardiac and respiratory motion artifacts degrade the image quality of lung CT in free-breathing children. The aim of this study was to evaluate the effect of combined electrocardiography (ECG) and respiratory triggering on respiratory misregistration artifacts on lung CT in free-breathing children.

  • Table 1: Examination protocol
  • 1. 7-year-old child with familial dilated cardiomyopathy and right ventricular thrombi. 1. Axial DECT PBV image shows perfusion defect in the left dorsal lung. Small right pleural effusion is noted.
  • 2. Sagittal DECT PBV image also shows perfusion defect in the left dorsal lung. Large thrombi (arrows) are seen in the right ventricle. Pericardial effusion is noted.
  • 3. VRT view of pulmonary vessels shows no evidence of thromboembolism in the major pulmonary arteries but decreased visualization of small peripheral pulmonary arterial branches in both lower lung fields.

At Asan Medical Center, DECT is routinely performed in children who are suspected of having pulmonary thromboembolism. Read more
