To explore the significance of digital three-dimensional reconstruction techniques in the diagnosis of female pelvic mass.
Original computed tomographic angiography (CTA) datasets of 72 patients with pelvic mass who were hospitalized in Southern Hospital of Southern Medical University from October 2009 to October 2012 were collected. All cases were undergone the B-mode ultrasound and CTA examination, the datasets were input into the Mimics Version 10.01 software respectively to construct digital three-dimensional models of pelvic, arterial blood network, pelvic mass and organs.On the basis of without knowing the diagnosis of the disease on CTA, two gynecologists gave the final diagnosis of the disease after observing and analyzing the supply blood vessels and the relationship between the adjacent organs of pelvic mass through rotate the three-dimensional model by single-blind method. Define the postoperative pathological diagnosis as the standard, and compare the coincidence rate between the postoperative pathological diagnosis with diagnosis results on different inspections (including B ultrasound results, CTA results or the diagnosis on the three-dimensional model of pelvic mass).
We successfully reconstructed 72 patients' three-dimensional model which could clearly display anatomic structure of pelvic bone, abdomen and pelvic arterial branches at different levels and the anatomic relationship between the mass and main organs in the pelvis. In all cases, 56 of them preoperative B-mode ultrasound examination were consistency with the postoperative pathological diagnosis, the coincidence rate was 78%, the preoperative CTA inspection results of 58 patients were consistency with the postoperative pathological diagnosis, the coincidence rate was 81%. While the diagnosis rate of 66 patients on the basis of digital three-dimensional model were consistency with that of the postoperative pathological diagnosis, the coincidence rate was 92%. Compared the compliance rate between diagnosis of pelvic mass based on the digital three-dimensional model and preoperative B-mode ultrasound, there were significant difference(P = 0.021).While compared with the preoperative CTA examination, there was not significant difference (P = 0.054).
The pelvic three-dimensional models in vivo constructed by the digital three-dimensional reconstruction technique could visually display the source of the blood supply and the relationship between the pelvic organs, and guide to diagnosis and assess preoperatively.
探讨数字三维重建技术在女性盆腔肿块诊断中的意义。
收集2009年10月至2012年10月在南方医科大学南方医院住院的72例盆腔肿块患者的原始计算机断层血管造影（CTA）数据集。所有病例均行B超和CTA检查，将数据集分别输入Mimics Version 10.01软件，构建盆腔、动脉血网、盆腔肿块及器官的数字三维模型。在不知CTA疾病诊断的基础上，两名妇科医生通过单盲法旋转三维模型观察分析盆腔肿块的供血血管及与相邻器官的关系后给出疾病最终诊断。以术后病理诊断为标准，比较术后病理诊断与不同检查（包括B超结果、CTA结果或盆腔肿块三维模型诊断）结果的符合率。
成功重建72例患者的三维模型，能清晰显示骨盆骨、腹部及不同层面盆腔动脉分支的解剖结构以及肿块与盆腔主要器官的解剖关系。所有病例中，术前B超检查56例与术后病理诊断一致，符合率为78%；术前CTA检查58例与术后病理诊断一致，符合率为81%。而基于数字三维模型诊断的66例与术后病理诊断一致，符合率为92%。数字三维模型诊断盆腔肿块的符合率与术前B超比较，差异有统计学意义（P = 0.021）。与术前CTA检查比较，差异无统计学意义（P = 0.054）。
数字三维重建技术构建的盆腔三维模型能直观显示供血来源及盆腔器官间的关系，术前指导诊断及评估。
