Head and neck squamous cell carcinoma (HNSCC) can either be examined with hybrid PET/MR imaging systems or sequentially, using PET/CT and MR imaging. Regardless of the acquisition technique, the superiority of MR imaging compared to CT lies in its potential to interrogate tumor and surrounding tissues with different sequences, including perfusion and diffusion. For this reason, PET/MR imaging is preferable for the detection and assessment of locoregional residual/recurrent HNSCC after therapy. In addition, MR imaging interpretation is facilitated when combined with PET. Nevertheless, distant metastases and distant second primary tumors are detected equally well with PET/MR imaging and PET/CT.
头颈部鳞状细胞癌 (HNSCC) 可以使用混合 PET/MR 成像系统进行检查，也可以使用 PET/CT 和 MR 成像进行顺序检查。无论采用哪种采集技术，MR 成像相对于 CT 的优势在于其具有通过不同序列（包括灌注和扩散）探查肿瘤和周围组织的潜力。出于这个原因，PET/MR 成像对于治疗后局部残留/复发性 HNSCC 的检测和评估是优选的。此外，与 PET 结合使用时，MR 成像的解释也变得更加容易。尽管如此，PET/MR 成像和 PET/CT 对远处转移和远处第二原发肿瘤的检测效果同样好。
