摘　　要：【目的】探讨增强3D STIR SPACE序列对盆腔子宫内膜异位症患者骶丛神经异常的显示价值,并与增强3D VIBE序列进行对比。【方法】病例组包括30名子宫内膜异位症患者,对照组包括20名健康女性,均接受盆腔MRI检查,包括对比增强3D STIR SPACE序列和增强3D VIBE序列。评估骶丛神经显示的图像质量以及子宫内膜异位症患者中的骶丛神经侵犯。【结果】对照组和病例组中,3D STIR SPACE序列和3D VIBE序列均能很好地显示骶丛神经纤维(P<0.001)。阅片者应用3D-STIR-SPACE序列对病变的诊断信心分数一致性较强(Kappa=0.684,P<0.001),应用3D-VIBE序列的诊断信心分数一致性一般(Kappa=0.130,P=0.386)。【结论】对比增强T2-SPACE序列和3D VIBE序列能够清晰显示骶丛神经,前者对盆腔子宫内膜异位症患者骶丛神经异常的显示更有优势。【Objective】To investigate the value of contrast enhanced 3D STIR SPACE sequence and compare it with contrast enhanced 3D VIBE sequence in displaying the sacral nerve plexus abnormalities in pelvic endometriosis.【Methods】All the 30 patients with endometriosis and 20 healthy women received pelvic MRI examinations by contrast enhanced 3D STIR SPACE sequence and contrast enhanced 3D VIBE sequence.Then we evaluated and analyzed the image quality and diagnostic confidence of the two sequences in identifying the sacral nerve plexus abnormalities.【Results】Sacral plexus nerve fibers were clearly revealed in both healthy controls and patients with endometriosis on 3D STIR SPACE sequence and 3D VIBE sequence.The consistency of diagnosis confidence by two readers using 3D-STIR-SPACE sequence was strong(Kappa=0.684,P<0.001),using 3D-VIBE sequence was moderate(Kappa=0.130,P=0.386).【Conclusions】Both 3D STIR SPACE sequence and 3D VIBE sequence can clearly display sacral plexus nerve fibers.3D STIR SPACE sequence has more advantages in showing sacral plexus abnormalities in pelvic endometriosis.
