To compare two different imaging modalities, magnetic resonance (MR), and three-dimensional sonography (3DUS), in order to evaluate the specific role in preoperative work-up of deep infiltrating endometriosis.
33 women with endometriosis underwent 3DUS and MR followed by surgical and histopathological investigations. Investigators described the disease extension in the following sites: torus uterinus and uterosacral ligaments (USL), vagina, rectovaginal-septum, rectosigmoid, bladder, ovaries. Results were compared with surgical and histopathological findings.
Ovarian and deep pelvic endometriosis were found by surgery and histology in, respectively, 24 (72.7%) and 22 (66.6%) of the 33 patients. Sensitivity and specificity values of 3DUS for the diagnosis of endometrial cysts were 87.5% and 100%, respectively; those of MRI were 96.8% and 91.1%, respectively. Sensitivity and specificity of 3DUS for the diagnosis of deep infiltrating endometriosis in specific sites were: USL 50% and 94.7%; vagina 84% and 80%; rectovaginal-septum 76.9% and 100%; rectosigmoid 33.3% and 100%; bladder 25% and 100%. Those of MR were: USL 69.2% and 94.3%; vagina 83.3% and 88.8%; rectovaginal-septum 76.4% and 100%; restosigmoid 75% and 100%; bladder 83.3% and 100%.
MR accurately diagnoses deep infiltrating endometriosis; 3DUS accurately diagnoses deep infiltrating endometriosis in specific locations.
比较两种不同的成像方式，即磁共振成像（MR）和三维超声检查（3DUS），以评估其在深部浸润性子宫内膜异位症术前检查中的特定作用。
33例患有子宫内膜异位症的女性接受了3DUS和MR检查，随后进行了手术及组织病理学检查。研究人员描述了疾病在以下部位的扩展情况：子宫隆凸和子宫骶韧带（USL）、阴道、直肠阴道隔、直肠乙状结肠、膀胱、卵巢。将结果与手术及组织病理学检查结果进行比较。
通过手术和组织学检查，在33例患者中分别发现24例（72.7%）存在卵巢子宫内膜异位症和22例（66.6%）存在深部盆腔子宫内膜异位症。3DUS诊断子宫内膜囊肿的敏感性和特异性值分别为87.5%和100%；MRI的敏感性和特异性值分别为96.8%和91.1%。3DUS诊断特定部位深部浸润性子宫内膜异位症的敏感性和特异性分别为：USL 50%和94.7%；阴道84%和80%；直肠阴道隔76.9%和100%；直肠乙状结肠33.3%和100%；膀胱25%和100%。MR的敏感性和特异性分别为：USL 69.2%和94.3%；阴道83.3%和88.8%；直肠阴道隔76.4%和100%；直肠乙状结肠75%和100%；膀胱83.3%和100%。
MR能准确诊断深部浸润性子宫内膜异位症；3DUS能准确诊断特定部位的深部浸润性子宫内膜异位症。
