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.

ReviewNormal Anatomic Structures and Variants of the Sinonasal Cavities, Orbit, and Jaw.
This article discusses mimics, anatomic variants, and pitfalls of imaging of the sinonasal cavity, orbit, and jaw. The authors discuss clinical findings and imaging pearls, which help in differentiating these from one another.

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.

ReviewNormal 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.

ReviewComputed Tomography Imaging Artifacts in the Head and Neck Region: Pitfalls and Solutions.
Computed tomography (CT) artifacts are aberrations that usually degrade the image quality of CT images, but occasionally provide insights regarding actual imaging findings. The presence of artifacts can be attributed to various sources, including patient, scanner, and postprocessing factors. ⋯ 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.
