Abstract:
ObjectiveTo 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. MethodsAll 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. ResultsSacral 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）. ConclusionsBoth 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.
