Thyroid gland disorders include benign and malignant thyroid nodules and diffuse thyroid disorders. The incidence of malignant thyroid nodules is low and the prognosis is good. The diagnosis of thyroid cancer and diffuse parenchymal disorders is generally based on clinical manifestations and histopathological evaluation. Ultrasonography has its place in the diagnostics and follow-up of thyroid ...

Stiffness of tissue is important information for cancer diagnosis, and it is also very commonly used for prostate cancer diagnosis. Digital rectal examination (DRE) is the easiest method to detect prostate cancer, but it has limited reproducibility, and lacks objectiveness. The positive predictive value of DRE alone has been shown to be as low as 30%. The second easiest imaging technique used f...

(EUS) is not only useful for providing excellent images for detection and staging of pancreatic cancer; it also provides guidance for fine needle aspiration (FNA) and biopsies detected during a standard procedure. Overall accuracy of EUS-FNA can be considered excellent, with sensitivities between 80% and 85%, and specificities close to 100%. However, differentiation between pancreatic cancer an...

In a cross-sectional study, published in Radiology, in vivo lumbar MR elastography was performed once in the morning and once in the afternoon in 47 subjects without low back pain. Patients were ages 20 to 71 years. Researchers used principal frequency analysis to assess degeneration grade and MR elastography-derived sheer stiffness of the nucleus pulposus and annulus fibrous regions of all lum...

Segmental testicular infarction (STI) is a rare cause of acute scrotum. The spectrum of findings on gray-scale and color Doppler ultrasonography differ depending on the time between the onset of testicular pain and the ultrasonography examination. We are not aware of the usefulness of shear-wave elastography for the diagnosis of STI. We report the shear-wave elastography features in a case of S...

It is ver y important to understand the stage of liver fibrosis and the level of inflammation both in a treatment plan setting and for predicting the prognosis of viral and other diffuse liver diseases. Liver biopsy is considered as the gold standard but it has problems relating to its invasiveness (pain and bleeding) and the possibility of bias due to sampling error. Recently, ultrasound elast...

Thyroid elastography has become, lately, one of the main focuses in thyroid imaging. With more than one hundred papers published on this subject, the core of accumulated knowledge justifies the need for a comprehensive review on the topic. The paper presents the various elastographic techniques used for thyroid assessment. Both strain and shear wave elastography, with all their variants, are di...

JED-M Elastography is a method used to evaluate the hardness of different tissues and is based on the principle that softer parts of tissues are easier to deform under compression than stiffer sections of tissues. Elastography translates the elastic properties of tissues into a map of different colors, which reads like a virtual biopsy; the stiffness of tissues is related to their histologic fe...

INTRODUCTION Characterization of muscle elasticity will improve the diagnosis and treatment of muscle disorders. The purpose is to compare the use of magnetic resonance elastography (MRE) and ultrasound elastography (USE) techniques to elucidate the MRE cartography of thigh muscles. METHODS Both elastography techniques were performed on 5 children and 7 adults. Quantitative (MRE) and qualitat...

Ultrasound elastography is a widely used technique for assessing the mechanical characteristics of tissues. Although there are several ultrasound elastography techniques, strain elastography (SE) is currently the most widely used technique for visualizing an elastographic map in real time. Among its various indications, SE is especially useful in evaluating the musculoskeletal system. In this a...
