背景：本研究的目的是评估术前超声检查（US）对甲状腺乳头状癌（PTC）患者甲状腺外扩展（ETE）预测的诊断性能，并比较超声和磁共振成像（MRI）对预测ETE的诊断性能。 方法：本研究对75例术前接受超声和MRI检查的PTC患者进行回顾性分析。两名放射科医生独立评估超声和磁共振检查结果，以评估 PTC 的最小或广泛 ETE。将这些结果与组织病理学结果进行比较。比较了US和MRI在ETE评估中的诊断性能。结果：US在预测最小ETE方面比MRI更准确(p < 0.05)，而在预测广泛ETE方面US和MRI的准确性没有显着差异。在预测总体 ETE 方面，US 表现出比 MRI 更高的敏感性、阴性预测值和准确性 (p < 0.001)。结论：在术前评估 PTC ETE 时，US 比 MR 成像在评估总体 ETE 方面具有更高的准确性，在最小 ETE 方面具有更高的敏感性。 US 和 MRI 在评估 PTC 的广泛 ETE 方面没有显着差异。 (C) 2014 Surgical Associates Ltd. 由 Elsevier Ltd 出版。保留所有权利。
Background: The purpose of this study was to assess the diagnostic performance of preoperative ultrasonography (US) for the prediction of extrathyroidal extension (ETE) in patients with papillary thyroid carcinoma (PTC) and to compare the diagnostic performances of US and magnetic resonance imaging (MRI) for predicting ETE.Methods: 75 patients with PTC who underwent preoperative US and MRI were retrospectively reviewed in this study. Two radiologists independently evaluated the US and MR findings to assess minimal or extensive ETE of PTC. These results were compared with the histopathologic findings. The diagnostic performances of US and MRI in the evaluation of ETE were compared.Results: US was more accurate than MRI in the prediction of minimal ETE (p < 0.05) and the accuracies were not significantly different between US and MRI in extensive ETE. US showed higher sensitivity, negative predictive value and accuracy than MRI (p < 0.001) in the prediction of overall ETE.Conclusion: US provided higher accuracy for assessing overall ETE and higher sensitivity for minimal ETE than MR imaging in preoperative evaluation of ETE of PTC. There was no significant difference in evaluating extensive ETE of PTC between US and MRI. (C) 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.
