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.
专门的磁共振成像（MR 成像）在评估原发性病变方面具有出色的性能，应定期添加到全身正电子发射断层扫描（PET）/MR 成像中，以进行初始分期。PET/MR 成像对检测淋巴结受累具有高度敏感性，并可与腋窝二次超声检查的高特异性相结合，以确认 N 分期。对于 M 分期，除了肺部病变外，PET/MR 成像在辐射剂量减半的情况下优于 PET/计算机断层扫描（CT）。通过放射组学和人工智能，有望提高 PET/MR 成像的多参数成像的预测价值。
