专用的磁共振成像技术在原发病灶的评估方面表现出色，应定期与全身PET / MR成像相结合用于初期分期。PET / MR成像对于淋巴结受累的检测非常敏感，并可以与腋窝第二次超声的高特异性相结合，以确定淋巴结分期。就M分期而言，除了肺部病变外，PET / MR成像优于PET / CT成像，且辐射剂量只有一半。PET / MR成像与放射组学和人工智能相结合能够提高多参数成像的预测价值。版权所有© 2023 Elsevier Inc. 保留所有权利。

Dedicated MR imaging is highly performant for the evaluation of the primary lesion and should regularly be added to whole-body PET/MR imaging for the initial staging. PET/MR imaging is highly sensitive for the detection of nodal involvement and could be combined with the high specificity of axillary second look ultrasound for the confirmation of the N staging. For M staging, with the exception of lung lesions, PET/MR imaging is superior to PET/computed tomography, at half the radiation dose. The predictive value of multiparametric imaging with PET/MR imaging holds promise to improve through radiomics and artificial intelligence.Copyright © 2023 Elsevier Inc. All rights reserved.
