Strain and Shear Wave Elastography in Thyroid Nodules: Tissue Stiffness as a Complementary Risk Marker for Differentiating Benign, Indeterminate, and Malignant Cytology

Head &Neck, EarlyView.
ABSTRACT Objective To evaluate the diagnostic performance of shear wave elastography (SWE) and strain elastography (SE) as complementary techniques to conventional B‐mode ultrasound for differentiating benign, indeterminate, and malignant thyroid nodules. Methods This prospective cross‐sectional study included 208 thyroid nodules evaluated using B‐mode

Diagnostic performance of ARFI ultrasound elastography in spleen stiffness measurement to predict esophageal varices [PDF]

Al Ameen Journal of Medical Sciences, 2022
Background: Presence esophageal varices are an independent predictor of mortality in patients with cirrhosis. Non-invasive assessment of cirrhotic patients to predict esophageal varices have been increasingly used instead of endoscopy.

Main elastography methods.

, 2018
In strain elastography (or quasi static elastography) (A), the operator press the tissue with imaging transducer. In the second case, the shear wave is generated by acoustic radiation force impulse excitation.

Endobronchial Ultrasound Elastography for Diagnosing Mediastinal and Hilar Lymph Nodes

Chinese Medical Journal, 2015
Background: Pathophysiological processes, such as malignancy, can lead to the formation of stiffer tissue in lung cancers. Endobronchial ultrasound (EBUS) elastography is a novel technique for measuring tissue stiffness during EBUS-guided transbronchial ...

Does shear wave ultrasound independently predict axillary lymph node metastasis in women with invasive breast cancer? [PDF]

, 2013
Shear wave elastography (SWE) shows promise as an adjunct to greyscale ultrasound examination in assessing breast masses. In breast cancer, higher lesion stiffness on SWE has been shown to be associated with features of poor prognosis.

Expert consensus on neuro‐musculoskeletal functional reconstruction for post‐stroke spastic hemiplegia

Ibrain, EarlyView.
This expert consensus proposes a patient‐centered pathway for functional reconstruction after post‐stroke spastic hemiplegia: “patient goal–pathophysiologic component–treatment target–functional reassessment.” Treatment selection and sequencing across motor retraining, brain–computer interfaces, peripheral nerve surgery, and tendon/soft‐tissue ...
