HDlive Flow with Spatiotemporal Image Correlation for Assessment of Fetal Goiter

Ab s t r Ac t Case description: We present our experience of diagnosing fetal goiter using radiant flow and HDlive flow with spatiotemporal image correlation (STIC). A 39-year-old pregnant Japanese woman, gravida 3, para 1, with Graves’ disease was referred to our ultrasound clinic at 37 weeks and 1 day of gestation because of suspected fetal goiter. Two-dimensional (2D) sonography revealed enlarged thyroid glands (left lobe, 29.5 × 22 mm; right lobe, 32.9 × 21.2 mm). Radiant flow showed abundant blood flow on both lobes. HDlive flow with STIC clearly demonstrated spatial relationships of pulsatile dilated blood vessels in the fetal goiter. Our results suggest that HDlive flow with STIC shows precise spatial vascularity with pulsation of fetal goiter in utero.
