摘要 目的 探讨MRI 3D-FIESTA序列在胎儿脊柱畸形的诊断价值。方法 回顾性分析58例胎儿的MRI脊柱图像,所有孕妇均在MRI采集前行产前超声并可疑脊柱病变。将2D-FIESTA及3D-FIESTA序列的图像质量以及诊断价值进行分级,并对两组图像质量进行比较。结果 共得到58例胎儿脊柱图像,发现畸形有半椎体19例、蝴蝶椎7例、融合椎5例、冠状裂3例、椎体骨化中心小14例、椎间隙窄3例、椎体骨化不均4例、阴性结果14例。2D图像分级的优、中等、差分别占31.03%、60.34%、8.63%,3D图像分别占81.03%、15.52%、3.45%,3D图像质量较2D图像高,差异具有统计学意义(P<0.05)。结论 3D-FIESTA序列能够更好地显示胎儿脊柱畸形,在2D序列扫描不满意时可加扫3D序列以提高胎儿脊柱畸形的检出率。 Objective To investigate the value of 3D-FIESTA sequence of MRI in fetal spinal malformation. Methods MRI spinal images of 58 fetuses were analyzed retrospectively. All pregnant women were diagnosed with suspected spinal abnormalities by prenatal ultrasound before MRI acquisition. Grade the image quality and diagnostic value of 2D-FIESTA and 3D-FIESTA sequences, and compare the image quality of the two groups. Results A total of 58 fetal spinal images were obtained by scanning. There were 19 cases of hemivertebrae, 7 cases of butterfly vertebrae, 5 cases of fusion vertebrae, 3 cases of coronary fissure, 14 cases of small ossification center of vertebral, 3 cases of narrow intervertebral space, 4 cases of uneven ossification of vertebrae, and 14 cases of negative results. The excellent, medium and poor grading of 2D images accounted for 31.03%,60.34% and 8.63% respectively, while the 3D images accounted for 81.03%,15.52% and 3.45% respectively. The quality of 3D images is higher than that of 2D images, and the difference is statistically significant(P<0.05). Conclusion 3D-FIESTA sequence can better display fetal spinal malformation than 2D.When 2D sequence scanning is not satisfactory, 3D sequence can be added to improve the detection rate of fetal spinal malformation.
