半椎体是一种常见的先天性脊柱异常,受累椎体的骨化中心发育不良,只有部分结构正常发育并骨化,可导致脊柱侧弯、前凸或后凸。本病二维超声表现具有特征性,其三维超声可清晰显示脊柱的连续性及侧弯程度,是二维超声的有益补充,现将我院二维及三维超声检查发现的胎儿半椎体畸形5例报告如下。 Hemi-vertebral body is a common congenital spinal abnormalities, involving the center of ossification of the vertebral body dysplasia, and only part of the normal development and ossification of the structure, can lead to scoliosis, lordosis or kyphosis. The two-dimensional ultrasound has the characteristic features of the three-dimensional ultrasound can clearly show the continuity of the spine and the degree of scoliosis is a useful complement to two-dimensional ultrasound is now in our hospital two-dimensional and three-dimensional ultrasound examination of fetal hemivertebra deformity 5 cases are as follows.
