目的：由于复杂的解剖结构和非特异性的生理和炎症FDG摄取，对头颈部正电子发射断层扫描/计算机断层扫描（PET/CT）研究的解释具有挑战性。我们提出了一个图集，常见的混淆因素遇到在我们institution.Materials和方法：我们提出了全身氟脱氧葡萄糖（FDG）PET/CT研究的20例患者的头部和颈部的各种混淆因素。大多数患者（15例）有头颈癌病史，其中5例合并其他原发肿瘤。结果：我们将这些病例分为以下类别：生理性摄取（6例），炎性摄取（5例），意外良性肿瘤（2例），意外恶性肿瘤（4例），放射后变化（2例），手术后变化（2例）和配准错误（1例）。了解常见变异、缺陷和治疗效果对于准确阅读头部和颈部区域的PET/CT至关重要。
Purpose: Interpretation of positron emission tomography/computed tomography (PET/CT) studies in the head and neck region is challenging due to the complex anatomy and nonspecific physiologic and inflammatory FDG uptake. We present an atlas of common confounding factors encountered at our institution.Materials and Methods: We present whole-body fluorodeoxyglucose (FDG) PET/CT studies of 20 patients with various confounding factors in the head and neck. Most patients (15) had a history of head and neck cancer and some (5) of them presented with other primary tumors.Results: We describe these cases under the following categories: physiologic uptake (6), inflammatory uptake (5), unexpected benign tumors (2), unexpected malignant tumors (4), postradiation changes (2), postsurgical changes (2), and misregistration (1).Conclusions: Knowledge of common variants, pitfalls, and treatment effects is essential in accurate reading of PET/CT in the head and neck region.
