- Abstract:
- Recent advances in ultrasound technology have enabled the diagnosis of overall tissue vascularization by three-dimensional (3D) power Doppler. This case report describes 3D power Doppler characteristics of unilateral ovarian torsion 2 weeks after embryo transfer in a pregnant patient with bilateral hyperstimulated ovaries. Before laparoscopic treatment the twisted right ovary showed the following 3D power Doppler indices: mean grayness index, 15.66; vacularization index, 0.24; flow index, 21.99; vascularization flow index, 0.05. One hour after laparoscopic treatment 3D power Doppler indices of the untwisted ovary were as follows: mean grayness index, 25.61; vacularization index, 3.81; flow index, 42.800; vascularization flow index, 1.63. The resistance index of the ovarian vessels before and after laparoscopy showed no significant difference (5.1 vs. 5.2). The diagnosis of ovarian torsion can be better made with 3D power Doppler sonography than with two-dimensional Doppler sonography.
