ReviewPearls, Pitfalls, and Mimics in Pediatric Head and Neck Imaging.
Children present with a spectrum of head and neck pathologies that differ from those found in the adult population, with specific image findings and clinical characteristics. This article reviews the imaging protocols, pearls and pitfalls, and mimics of pediatric head and neck lesions, stressing the combination of key radiological findings, clinical presentation, and anatomic localization necessary to correctly interpret the imaging.

ReviewParathyroid Computed Tomography: Pearls, Pitfalls, and Our Approach.
Parathyroid imaging is predominantly used for preoperative localization of parathyroid lesions in patients with the biochemical diagnosis of primary hyperparathyroidism. Although imaging algorithms vary, in the era of minimally invasive parathyroidectomy for single parathyroid adenomas, multiphase parathyroid computed tomography (CT) (4-dimensional CT) has emerged as a favored modality for presurgical mapping of parathyroid lesions. Implementation and correct interpretation of these studies can be challenging, although confidence and accuracy improve with experience and volume. This article reviews our approach to parathyroid imaging, focusing on pearls and pitfalls in parathyroid CT with ultrasound as a supportive and complementary modality.

ReviewMR Imaging Artifacts in the Head and Neck Region: Pitfalls and Solutions.
MR Imaging artifacts are features appearing in MR images that are not present in the original anatomy. MR imaging artifacts can be patient-related, hardware-related, or signal-processing-related and affect diagnostic quality or mimic pathology. It is necessary to take MR imaging artifacts into consideration when interpreting images. A basic knowledge of MR imaging physics and the potential origin of MR imaging artifacts can help to find solutions to eliminate or reduce the influence of artifacts on image quality by adjusting acquisition parameters appropriately for a better diagnosis.

18FDG-PET plays an important role in cancer imaging. However, there are certain challenges with interpreting head and neck 18FDG-PET. In this article, examples of technical issues that can undermine the interpretation of the scans, normal physiologic activity that can mimic lesions or obscure lesions, and causes of false positives and false negatives on posttreatment cancer imaging are discussed. In addition, suggestions for addressing potential pitfalls on head and neck 18FDG-PET are highlighted.
