Inability of shear-wave elastography to distinguish malignant from benign prostate tissue – a comparison of biopsy, whole-mount sectioning and shear-wave elastography

Aim: This study was designed to assess the possible usefulness of shear-wave elastography in differentiating between benign and malignant tissue in prostate neoplasia. Patients and methods: A total of 120 prostate tissue samples were obtained from 10 patients treated by radical prostatectomy and investigated pre-operatively by ultrasound elastography followed by directed biopsy. After resection, whole-mount sectioning and histological examination was performed. The predictions based on shear

Introduction to ultrasound elastography

. In the 90's, ultrasonography was extended by the option of examining the stiffness of tissue by estimating the difference in backscattering of ultrasound in compressed and non-compressed tissue. This modality is referred to as the static, compression elastography and is based on tracking the deformation of tissue subjected to the slowly varying compression through the recording of the backscattered echoes. The displacement is estimated using the methods of cross-correlation between consecutive

New aspects in shear-wave elastography of prostate cancer

Aim: This study was designed to evaluate the performance of shear-wave elastography as a diagnostic tool for prostate cancer in a larger cohort of patients than previouslyreported. Patients and methods: Seventy-three patients with suspected prostate carcinoma were investigated by ultrasound elastography followed by directed biopsy. The elastographic and histological results for all biopsies were compared. Results: After exclusion of invalid and non-assessable results, 794 samples were obtained

In the subacute and chronic stages, ultrasound can be of value to follow up injured muscle during the healing process and identify complications that may require special treatment(4–8). In addition to morphological features, ultrasound imaging combined with strain and shear wave elastography can also provide information on the mechanical properties of intact and diseased muscle tissue, thus allowing assessment of muscle biomechanics in the clinical setting(9–16).

Clinical applications of spleen ultrasound elastography – a review

In the last few years, notable technical progress has taken place in ultrasound elastography. Qualitative methods have been replaced by quantitative ones, such as: transient elastography, acoustic radiation force impulse and shear wave elastography. Owing to the fact that the spleen is superficially located, it is possible to obtain reliable measuring accuracy of its hardness using sonoelastography. Lately, many researchers have been investigating how spleen elasticity changes in patients

Shear wave elastography with a new reliability indicator

Non-invasive methods for liver stiffness assessment have been introduced over recent years. Of these, two main methods for estimating liver fibrosis using ultrasound elastography have become established in clinical practice: shear wave elastography and quasi-static or strain elastography. Shear waves are waves with a motion perpendicular (lateral) to the direction of the generating force. Shear waves travel relatively slowly (between 1 and 10 m/s). The stiffness of the liver tissue can be

The usage of contrast agents enables unambiguous differentiation between benign and malignant focal lesions, frequently allowing them to be identifi ed accurately without the assistance of other imaging modalities.

Sonoelastographic evaluation for benign neck lymph nodes and parathyroid lesions

Abstract Aim: The aim of the study was to evaluate the performance of real-time strain sonoelastography for comparison of perithyroidal lymph nodes of Hashimoto thyroiditis patients, jugular lymph nodes of healthy individuals and parathyroid lesions. Material and methods: Fifty parathyroid lesions (Group 1), 52 lymph nodes in Hashimoto thyroiditis patients (Group 2) and 51 reactive jugular lymph nodes (Group 3) were examined by ultrasound, and elastography was performed for a total of 95

technique(12,13). Currently, two main types of elastography are available: shear wave elastography (SWE) and strain elastography (SE). Some authors have suggested that SWE is superior to SE in thyroid nodule stratification because of its operator independency, but recent meta-analyses have surprisingly shown that SE has better diagnostic accuracy than SWE(14,15) In addition, Dighe et al. described SWE artifacts and their impact on final results(16). In this paper, the authors suggested that almost 70

Modified sonoelastographic scale score for lymph node assessment in lymphoma – a preliminary report 

Elastography is a new method of assessment of lymph node consistency. The majority of papers focus on metastases detection of head and neck or breast tumors. The typical desmoplastic reaction in connective tissue stroma in cancer, which is responsible for tissue’s hardening, is seen in lymphoma less frequently. Material and methods: Study of 15 patients with active Hodgkin and non-Hodgkin lymphomas and 16 previously treated patients with no evidence of recurrence. A total of 60 patients

However, diagnostic ultrasound is still a controversial method due to numerous and often divergent classification systems for varicocele assessment as well as its poor correlation with clinical manifestations. As a result of introduction of clear ultrasound criteria as well as the development of elastography and nuclear magnetic resonance, diagnostic imaging can play an important role in assessing the risk of damage to the testicular parenchyma

Chest wall – underappreciated structure in sonography. Part I: Examination methodology and ultrasound anatomy

differences in the anatomy of the ribs, ster­num, scapula and sternoclavicular joints have been discussed. The rich vascular network which is only fragmentarily accessible for ultrasound assessment has been briefly discussed. A comprehensive evaluation of the chest wall should include the axillary, supraclavicular, apical and parasternal lymph nodes. Their examination requires the use of elastography and contrast-enhanced ultrasound.
