Computed Tomography Imaging Artifacts in the Head and Neck Region
This article reviews various types of CT artifacts that can be encountered in the head and neck region and explain how these artifacts may be mitigated. While we cannot fully eliminate the occurrence of CT artifacts, building an awareness of their cause provides reading physicians the tools to detect and read through their presence. Further, this knowledge may be applied to contribute to protocol adjustments to improve a site ’s overall imaging practice. (Source: Neuroimaging Clinics)

MR Imaging Artifacts in the Head and Neck Region
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 influe nce of artifacts on image quality by adjusting acquisition parameters appropriately for a better diagnosis.

Postsurgical and Postradiation Findings in the Head and Neck Imaging
Surgical procedures and radiation therapy can have recognizable features on diagnostic imaging that should be recognized by the radiologist. Although it is a good practice to reference the surgical and clinical notes regarding any procedures that may have been performed in the head and neck, this information is not always available. Selected examples of posttreatment findings and potential mimics are described and depicted in the following sections. (Source: Neuroimaging Clinics)

Implants and Foreign Bodies on Head and Neck Imaging
A wide variety of foreign bodies can be encountered on head and neck imaging. These foreign bodies might include comestible foreign bodies, retained foreign bodies from trauma, and surgically implanted devices. The imaging features of these items are reviewed in this article.

Pearls and Pitfalls of 18FDG-PET Head and Neck Imaging
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. (Source: Neuroimaging Clinics)

Normal Anatomic Structures, Variants, and Mimics of the Temporal Bone
Various anatomic structures and variants in the temporal bone are potential radiological mimics and surgical hazards. The imaging features of normal variants and lesions with similar imaging appearance are presented in this article. Throughout the article, salient features that can help elucidate the distinguishing features between mimics and imaging pitfalls are presented. (Source: Neuroimaging Clinics)

Pearls and Pitfalls in Neck Imaging
This article highlights some pearls and pitfalls encountered in neck imaging. It first covers normal anatomic structures that can be mistaken for pathology. Pathologic entities that can share similar imaging appearances are subsequently discussed. The article later touches on several essential anatomic distinctions. Finally, the selection of appropriate imaging modalities for certain clinical indications is discussed. (Source: Neuroimaging Clinics)

Normal Vascular Structures and Variants on Head and Neck Imaging
The vasculature of the neck, comprised of arteries and veins, provides for the supply and return of blood to and from the brain, and to structures of the neck and face. Knowledge of normal appearance and anatomy, and anatomic variants, may help one distinguish between normal and pathologic processes in the neck, which may affect diagnosis or choice of surgical approach. Other related structures that are important to recognize include the thoracic duct and carotid body. In this article examples of mostly computed tomography and MR imaging of normal anatomy and some of these variants are shown. (Source: Neuroimaging Clinics)

Mimics, Pearls, and Pitfalls of Head and Neck Imaging
Head and neck radiology can be very complex and challenging! Many factors can compromise the successful acquisition and interpretation of head and neck imaging studies. These can be related to the type of imaging modality, anatomical variants, the nature of certain lesions, and factors related to interpreter abilities. (Source: Neuroimaging Clinics)
