Cancers of the prostate have traditionally been detected by digital palpation which identifies increased stiffness (modulus of elasticity, hardness) of the abnormal tissue. Gray-scale ultrasound is insensitive to stiffness as an imaging parameter and often fails to reveal the extent or existence of a prostate cancer. Recent developments in technology and understanding have improved the diagnostic efficacy of transrectal ultrasound for detection of early prostate cancer, but even when coupled…

Imaging and Estimation of Tissue Elasticity by Ultrasound

    Ultrasound quarterly
  • 2007
TLDR
Recent work in assessing porous materials using elastography suggests that the technique may be useful in monitoring the severity of lymphedema, and US-based methods may be the most widely used for the near future.
Ultrasound elastography - review of techniques and its clinical applications.
TLDR
Ultrasound devices equipped with sonoelastography option enable more accurate imaging and evaluation of the nature of lesions situated at small depth, e.g. breast, thyroid, testicles, prostate, some groups of lymph nodes.
Biophysical Bases of Elasticity Imaging
TLDR
Tissue hardness can actually be quantified in terms of the tissue elastic moduli and may provide good contrast between normal and abnormal tissues based on the large relative variation in shear (or Young’s) elastic modulus.
Medical ultrasound: imaging of soft tissue strain and elasticity
TLDR
It is concluded that ultrasonic imaging of soft tissue strain and elasticity is now sufficiently well developed to have clinical utility and is anticipated that the technology will become a powerful mainstream investigative tool.
Evaluation of the Soft Tissue Elasticity with Forced Vibration by Ultrasonic Pulsed Doppler Method
TLDR
In this study, one dimensional distribution of the vibration amplitude inside the agar phantom is detected by Doppler ultrasound, then the relative hardness of tissues is evaluated by using above mentioned method.
Methods and Approaches in Ultrasound Elastography
TLDR
This chapter provides an overview of the key concepts of current ultrasound-based elastography methods and their potential clinical applications and guides readers through the pros and cons of individual concepts, thereby helping them to gain insight into the basic principles of USE.
US elastography of breast and prostate lesions.
TLDR
The sonoelastographic appearances of several common breast lesions, including fibroadenomas, simple and complex cysts, ductal carcinomas, malignant lymph nodes, and hematomas, are reviewed and potential pitfalls in the interpretation of elastograms, including false-positive and false-negative images, are illustrated.
Shear strain elastography
TLDR
An alternate approach for elasticity imaging is proposed and theoretical analysis suggests that signal decorrelation under lateral shear will be very small, coupled with the minimal artifacts visible in the shear strain images may make shear elastography an attractive alternative to techniques.
Harmonic Motion Imaging (HMI) for Tumor Imaging and Treatment Monitoring.
TLDR
HMI may constitute a non-ionizing, cost-efficient and reliable complementary method for noninvasive tumor detection, localization, diagnosis and treatment monitoring, and could accurately detect and characterize the tumor or thermal lesion based on its distinct properties.
AN OVERVIEW OF ELASTOGRAPHY - AN EMERGING BRANCH OF MEDICAL IMAGING.
TLDR
This paper presents a classification of elasticity measurement and imaging techniques based on the methods used for generating a stress in the tissue, and measurement of the tissue response and presents various techniques of EI.

TLDR
The majority of carcinomas in this series showed capsular involvement and ten penetrated and extended beyond the prostatic capsule, and all appeared to originate in the peripheral zone of the prostate and produced asymmetry of the gland.

[Radiological aspects of gastric localizations of malignant non-Hodgkin's lymphoma. Apropos of 50 cases].
TLDR
Combination of several peculiar radiologic signs suggest gastric lymphoma in 56 per cent of all the cases (16 per cent for endoscopy alone); this fact demonstrate the necessity of barium meal for a more accurate diagnosis of Gastric lymphomas.
Noninvasive measurement of cardiac pressures by induced ventricular wall resonance: preliminary results in the dog.
TLDR
Externally induced cardiac wall vibrations produced low frequency signals which, when subjected to spectrum analysis and coherent signal processing, permitted close approximation of static pressures and wave forms in the right ventricle at normal and hypertensive levels.
