MR imaging is the modality of choice in evaluation of salivary gland tumors. Postcontrast MR imaging is adequate for exact localization and extension of salivary gland tumors and multiparametric of diffusion-weighted and dynamic contrast-enhanced MR imaging helps in characterization of benign and malignant salivary gland tumors. Imaging is important for preoperative localization, characterization of salivary gland tumors and locoregional extension, perineural spread, and nodal and distant staging of malignant salivary gland tumors...

Neoplastic and non-neoplastic lesions may involve the minor salivary glands. Tumors of minor salivary glands are commonly seen in the oral cavity. Malignant tumors are more common than benign minor salivary gland tumors. The most common malignant tumors are adenoid cystic carcinoma and mucoepidermoid carcinoma, and the most common benign tumor is pleomorphic adenoma. Non-neoplastic lesions may involve minor salivary glands such as Sjogrene disease, immunoglobulin G4-related disease, necrotizing sialometaplasia, and subacute necrotizing sialadenitis...

Ultrasound is the preferred initial imaging modality in Europe and Asia for assessing the major salivary glands. In experienced hands, it is sensitive for a range of salivary pathologies, often diagnostic, and also a safe, cost-effective gatekeeper for further investigations as well as image-guided diagnostic biopsies and aspirations. This article reviews the scanning technique and normal sonographic anatomy of major salivary glands and overviews typical sonographic appearances of salivary pathologies, including infective and inflammatory conditions, sialolithiasis, and neoplasms...

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. Clinically, inflammation of the salivary gland causes pain and localized swelling. The presentation may be acute or chronic, and can be recurrent. Because there is significant overlap of underlying disease mechanisms and clinical presentations, radiologic evaluation often plays a significant role in evaluation...

This article reviews the role of routine and advanced diffusion imaging modules of the salivary glands. Routine and advanced diffusion imaging modules have a role in differentiation of malignant from benign salivary gland tumors, characterization of some benign salivary gland tumors, and staging of salivary gland cancer. The role of advanced diffusion modules in patients with salivary gland cancer after surgery, radiation therapy, or radioiodine therapy is discussed. Advanced diffusion imaging modules can help in diagnosis and staging of Sjögren syndrome...

REVIEW
Amit K Agarwal, Sangam G Kanekar
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 spectrum of diseases in these regions varies from simple infection to advanced malignancy, not just from the gland itself but also from the surrounding structures. The most common abnormalities in these spaces are inflammatory and infectious, and computed tomography is currently the most common imaging modality used...

Salivary gland diseases in children are uncommon, and the relative incidence of pathologies is different than in adults. This article presents a comprehensive review of congenital and acquired disorders that affect the major salivary glands in the pediatric population, highlighting the imaging findings that are important in defining the appropriate diagnosis or narrowing of the differential diagnosis.

The aim of this study is to review the imaging appearance of posttreatment salivary gland tumors. The authors discuss the imaging appearance of parotidectomy and reconstructive surgery of parotid defects. Imaging is important to diagnose tumor recurrence and also assess for complications related to surgery, such as a sialocele, fluid collection, hematoma, pseudoaneurysm, and graft stenosis. The article also provides a current-state assessment of the applications of advanced imaging techniques.

The salivary glands are commonly affected in systemic autoimmune disease and diseases of unknown pathogenesis. Sjögren syndrome (SjS) can be affected by other systemic diseases. Immunoglobulin G4-related disease (IgG4-RD) commonly affects salivary glands. Imaging findings are usually nonspecific; however, radiologists should be familiar with the manifestations to avoid diagnostic delay. Findings of early-stage SjS are difficult to identify on routine computed tomography or MR imaging. Chronic SjS can be diagnosed from MR imaging and sialographic findings...

REVIEW
Remy Lobo, Jeffrey Hawk, Ashok Srinivasan
Major and minor salivary gland malignancies come in various shapes and sizes. They can present as palpable masses or can be detected incidentally when imaging patients for other indications. A complete evaluation of salivary gland malignancies requires knowledge of the anatomy and various routes of spread of neoplasias. Computed tomography (CT) and MR imaging are complementary tools in this respect and offer useful information to the proceduralist. Advanced imaging (diffusion-weighted imaging and PET-CT) and other modalities (eg, ultrasound) help with characterization, although biopsy or excision is often needed for definitive tissue diagnosis...

This article reviews the multimodality diagnostic imaging features of benign neoplastic and nonneoplastic tumors associated with the major salivary glands. Examples of neoplastic conditions that are depicted and discussed include pleomorphic adenoma, Warthin tumor, oncocytoma, peripheral nerve sheath tumors, lipoma, and hemangiomas or hemangioendotheliomas. Examples of nonneoplastic conditions that are depicted and discussed include ranulas, benign lymphoepithelial lesions, Kimura disease, and vascular malformations...

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...

REVIEW

Although susceptibility-weighted imaging (SWI) studies have suggested an increased number of microhemorrhages in concussion, most show no significant differences compared with controls. There have been mixed results on using SWI to predict neurologic outcomes. Drawbacks include inability to time microhemorrhages and difficulty in attributing them to the concussion. Magnetic resonance spectroscopy (MRS) in concussion can identify metabolic abnormalities, with many studies showing correlations with clinical outcome...

Myelin water imaging (MWI) provides mild traumatic brain injury (mTBI) researchers with a specific myelin biomarker and helps to further elucidate microstructural and microarchitectural changes of white matter after mTBI. Improvement of scanner hardware and software with the implementation of MWI across scanner platforms will likely result in increased research regarding the role of myelin in traumatic brain injury (TBI). Future research should include detailed investigation of myelin between 2 weeks and 2 months after injury, the use of MWI in moderate and severe TBI, and investigation of the role of myelin in chronic TBI...

Traumatic brain injury (TBI) is a significant problem worldwide and neuroimaging plays a critical role in diagnosis and management. Recently, perfusion neuroimaging techniques have been explored in TBI to determine and characterize potential perfusion neuroimaging biomarkers to aid in diagnosis, treatment, and prognosis. In this article, computed tomography (CT) bolus perfusion, MR imaging bolus perfusion, MR imaging arterial spin labeling perfusion, and xenon CT are reviewed with a focus on their applications in acute TBI...
