ReviewNeurologic Emergencies in Pediatric Patients Including Accidental and Nonaccidental Trauma.
This article summarizes common neurologic emergencies presenting in pediatric patients. Imaging techniques and appearances of specific conditions are detailed, including pearls and pitfalls for each presentation. Specific attention is given to differential diagnoses that can serve as mimickers of pediatric neurologic emergencies.

ReviewHead and Neck Injuries: Special Considerations in the Elderly Patient.
Traumatic injuries to the head and neck are common in the elderly, which is a rapidly growing sector of the American population. Most injuries result from low-energy falls and therefore might be at risk for delayed presentation and undertriage. Imaging, particularly with computed tomography, plays a vital role in the evaluation of traumatic head and neck injuries in geriatric patients. A thorough understanding of the differing patterns of trauma in the elderly patient and the factors that are associated with poorer outcomes is essential.

Sialadenitis is among the most common conditions that affect the salivary glands. Inflammation of the salivary glands occurs as the end result of a variety of pathologic conditions, including infectious, autoimmune, and idiopathic causes. ⋯ Because there is significant overlap of underlying disease mechanisms and clinical presentations, radiologic evaluation often plays a significant role in evaluation. This article is a brief review of sialadenitis, including disease mechanisms, causes, and the practical imaging of the salivary glands.

ReviewImaging of Submandibular and Sublingual Salivary Glands.
The submandibular and sublingual salivary glands are major salivary glands with a wide spectrum of pathologic conditions. The corresponding spaces along the floor of mouth have complex anatomy, best evaluated with cross-sectional imaging. ⋯ The most common abnormalities in these spaces are inflammatory and infectious, and computed tomography is currently the most common imaging modality used. The anatomy of these spaces is much better depicted with MR; however, all the modalities have their unique roles.

ReviewCross-Sectional Imaging Techniques and Normal Anatomy of the Salivary Glands.
The salivary glands play an important role in digestion and oral hygiene, and give rise to a variety of benign and malignant pathologies. In suspected pathology, the goal of imaging is to confirm a lesion as being of salivary gland origin, narrow the list of differential considerations, define the extent of disease, and guide further management decisions. This review outlines the function, embryologic development, anatomy, and normal imaging features of the major salivary glands. The article also discusses imaging indications, the general approach to imaging the salivary glands, and the commonly used cross-sectional techniques used for evaluating the salivary gland.
