To reveal morphological differences between extranodal non-Hodgkin's lymphoma (NHL) and squamous cell carcinoma of the naso- and oropharynx, and to evaluate the usefulness of diffusion-weighted (DW) and (18)F-fluorodeoxyglucose PET/CT imaging.
Imaging findings, signal intensities, apparent diffusion coefficients (ADCs), and maximum standardized uptake values (SUVmax) were assessed.
Wall-thickening type, bilateral symmetry, and absence of nodal necrosis were more frequently seen with NHL. In NHL, signal intensities on DW images were higher, and ADCs was lower. No significant difference in SUVmax was found.
Only magnetic resonance imaging including DW imaging produced helpful data, eliminating the need for multimodality imaging.
揭示结外非霍奇金淋巴瘤（NHL）与鼻腔和口咽鳞状细胞癌之间的形态学差异，并评估弥散加权（DW）和（18）F-氟代脱氧葡萄糖 PET/CT 成像的有用性。
评估了影像学表现、信号强度、表观扩散系数（ADC）和最大标准化摄取值（SUVmax）。
NHL 更常表现为壁增厚型、双侧对称和无淋巴结坏死。在 NHL 中，DW 图像上的信号强度更高，ADC 较低。SUVmax 无显著差异。
只有包括 DW 成像在内的磁共振成像才能提供有帮助的数据，从而无需进行多模态成像。
