Diagnostic efficacy of virtual organ computer-assisted analysis in measuring the volume ratio of subchorionic hematoma with serum progesterone

Figure 1 Transvaginal three-dimensional ultrasound showed three-dimensional volume of gestational sac, three-dimensional volume of subchorionic hematoma, and this patient showed fetal arrest at 18 wk. A: Three-dimensional volume of gestational sac was 42.84 cm³; B: Three-dimensional volume of subchorionic hematoma was 3.79 cm³.
