Abstract
BACKGROUND Magnetic resonance elastography (MRE) is a rapidly developing medical imaging technique that allows for quantitative assessment of the biomechanical properties of the tissue. MRE is now regarded as the most accurate noninvasive test for detecting and staging liver fibrosis. A two-dimensional (2D MRE) acquisition version is currently deployed at >2000 locations worldwide. 2D MRE allows for the evaluation of the magnitude of the complex shear modulus, also referred to as stiffness. The development of 3D vector MRE has enabled researchers to assess the biomechanical properties of small organs where wave propagation cannot be adequately analyzed with the 2D MRE imaging approach used in the liver. In 3D vector MRE, the shear waves are imaged and processed throughout a 3D volume and processed with an algorithm that accounts for wave propagation in any direction. Additionally, the motion is also imaged in x, y, and z directions at each voxel, allowing for more advanced processing to be applied. PURPOSE This review describes the technical principles of 3D vector MRE, surveys its clinical applications in small organs, and discusses potential clinical significance of 3D vector MRE. CONCLUSION 3D vector MRE is a promising tool for characterizing the biomechanical properties of small organs such as the uterus, pancreas, thyroid, prostate, and salivary glands. However, its potential has not yet been fully explored.

Abstract
The salivary glands are located superficially and are therefore easily accessible to ultrasound (US) examination, particularly if a high-frequency probe designed for small parts is used. Hence, US examination of these organs is widely applied particularly in non-neoplastic pathologies. In this way, it is possible to obtain adequate images without the use of ionizing radiation or complex instrumentation such as magnetic resonance imaging. However, US examination requires an expert clinical knowledge and familiarity with the normal and pathological US anatomy of the area. Limitations and pitfalls linked to US examination of this area should also be kept in mind.
