Figure 1

(a, b) Left high parasternal view. (c, f) Computed tomographic pulmonary angiography shows a dilated pulmonary artery (PA) but no artifacts. (d) Color Doppler imaging with patent ductus arteriosus flow. (e) Near-suprasternal aortic short-axis view. A linear artifact is clearly seen ((a, b, d, e): white arrowheads). The thymus gland is seen ((a, b, e, f): red arrowheads).
