Elastography of the Breast
Overview of Breast Elastography Elastography should be performed in conjunction with conventional breast ultrasound. It is an additional imaging mode, like color Doppler, to evaluate a breast lesion or nonmass…
Principles of Elastography
Principles of Elastography Richard G. Barr 2.1 Introduction Elastography, or elasticity imaging, is a newer ultrasound imaging modality that can provide clinically useful information about tissue stiffness (rather than anatomy), which…
Elastography of the Lymph Nodes
Conventional Ways of Diagnosing Lymphadenopathy Lymph nodes are the guardians at checkpoints in the human body and send alarm signals in response to many pathologic conditions. Often, they are the…
Elastography of the Salivary Glands, Lymph Nodes, and Testes
Several criteria for distinguishing between benign and malignant lesions are well described in ultrasound examinations of parotid tumors (▶ Fig. 11.1a). Benign tumors usually have been reported to present with…
Elastography of the Musculoskeletal System
Structures with anisotropy have different acoustic properties in different directions, as just mentioned. It is important to have the transducer perpendicular to the structure so the angle of incidence of…
Elastography of the Thyroid Gland
Strain Elastography Imaging 6.2.1 Technique Today strain elastography (SE) is the elastography method most widely available in ultrasound equipment for thyroid evaluation. SE may be performed on longitudinal or axial planes….
Elastography of the Spleen, Pancreas, and Kidneys
Strain Elastography Limited evaluation of SE has been performed on the spleen. Shear Wave Elastography The reported mean elasticity values of normal spleen, calculated by means of SWE, were 2.9…
Magnetic Resonance Elastography
The acoustic waves used in MRE are generated by a dedicated active driver system. Due to the limitation on the use of magnetic components within a strong magnetic field, the…
Future Applications for Elastography
One application that requires a slow compression is poroelastography, in which the flow of interstitial fluid under compression, which occurs over several seconds, is measured. The clinical analogy is the…
Elastography of the Prostate
Prostate Cancer Screening PCa systematic screening has been challenged again following the publication of the recent recommendations by the French National Authority for Health (HAS).2 The aim of systematic screening…
