Routine and Advanced Ultrasound of Major Salivary Glands.

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.

Feasibility Study of Texture Analysis Using Ultrasound Shear Wave Elastography to Predict Malignancy in Thyroid Nodules.

Textural analysis of ultrasound shear wave elastography (SWE) was evaluated to discriminate benign and malignant thyroid nodules. Sixteen papillary thyroid cancers and 89 benign hyperplastic nodules in 105 patients underwent SWE using four static pre-compression levels. Fifteen gray level co-occurrence matrix textural features and six absolute SWE indices were computed from SWE images.

Magnetic resonance imaging staging of nasopharyngeal carcinoma in the head and neck.

Magnetic resonance imaging (MRI) is the modality of choice for staging nasopharyngeal carcinoma in the head and neck. This article will review the patterns of primary and nodal spread on MRI with reference to the latest 7th edition of the International Union Against Cancer/American Joint Committee on Cancer staging system.
