BACKGROUND Ultrasound elastography is an imaging modality used to show tissue stiffness in tumor pathophysiological processes that promote the formation of stiffer tissues. Endobronchial ultrasound (EBUS) elastography is an ultrasound elastography-based technique for measuring tissue stiffness during EBUS-guided transbronchial needle aspiration (EBUS-TBNA). The diagnostic value of EBUS elastography in central lung lesions remains largely unknown. MATERIAL AND METHODS A total of 57 patients with central lung lesions underwent ultrasonic bronchoscope examination...

AIMS: Maternal red blood cell alloimmunization is an important cause of fetal morbidity and mortality in the perinatal period, despite well-organized prophylaxis programs. The objective of the study was to evaluate placental elasticity by using Acoustic Radiation Force Impulse (ARFI) in Rhesus (Rh) alloimmunized pregnant women with hydropic and nonhydropic fetuses and to compare those with healthy pregnant women. MATERIAL AND METHODS: This case-control and descriptive study comprised twenty-eight healthy pregnant women, 14 Rh alloimmunized pregnant women with nonhydropic fetuses, and 16 Rh alloimmunized pregnant women with hydropic fetuses in the third trimester of pregnancy...

OBJECTIVES: In recent years, an increasing need to use imaging to assess normal and adaptive muscle function, in addition to its anatomy and structure, has emerged. We evaluated the myotendinous junction's elastosonographic behavior in light of the most recent literature on its physiologic behavior. The elastosonographic studies were compared with the results obtained from a standard measurement system to ensure a correlation with maximal muscle contraction. METHODS: Nineteen male professional soccer players were assessed during functional tests...

AIM: To evaluate the role of gray scale ultrasonography (US) and real time elastosonography (RTE) in carpal tunnel syndrome (CTS). MATERIALS AND METHODS: Both wrists of 18 healthy volunteers (n=36) formed the control group (Group 1) and 19 symptomatic outpatients of the neurology clinic constituted the patient group. According to nerve conduction study results, cases with mild CTS (n=15) formed Group 2; cases with moderate to severe CTS (n=20) formed Group 3. Cross sectional area (CSA) and strain ratio (SR) were measured at carpal tunnel inlet (CTI) and 4 cm proximal to the distal end of the radius (P)...

BACKGROUND: To study the safety, feasibility and skin effects of irreversible electroporation (IRE) for breast tissue and breast cancer in animal models. METHODS: Eight pigs were used in this study. IRE was performed on the left breasts of the pigs with different skin-electrode distances, and the right breasts were used as controls. The electrodes were placed 1-8 mm away from the skin, with an electrode spacing of 1.5-2 cm. Imaging and pathological examinations were performed at specific time points for follow-up evaluation...

BACKGROUND: Sonoelastography plays today a major role in musculoskeletal disease, showing minor muscle injuries not well appreciable in conventional B-mode ultrasonography and integrating it in major muscle injuries diagnosis. The aim of this study was to demonstrate the ability of elastosonography in the diagnosis of muscular contracture in football players presenting negative basic echography. METHODS: We examined twenty-two football players using basic echography and elastosonography approximately 24-48 hours after the traumatic event and we subsequently re-evaluated them after two weeks...

STUDY DESIGN: One hundred and six women with a sonographic finding of thickened endometrium were enrolled in this study. All patients underwent B-mode scanning and elastosonography, performed by the same operator who was blinded to the study design. After sonographic evaluation, all patients underwent endometrial tissue sampling via dilatation and curettage...

AIM: Vascular damage and fibrotic process represent the pathophysiological hallmarks of systemic sclerosis (SSc). Peripheral microangiopathy can be early detected by nailfold videocapillaroscopy (NVC), whereas recent studies suggest that ultrasound real time elastosonography (US-RTE) can be a useful tool to evaluate the reduction of skin elasticity. The aim of our study was to investigate possible correlations between NVC microvascular alterations and finger tissue stiffness evaluated with US-RTE in SSc subjects...

The main goal in meningioma surgery is to achieve complete tumor removal, when possible, while improving or preserving patient neurological functions. Intraoperative imaging guidance is one fundamental tool for such achievement. In this regard, intra-operative ultrasound (ioUS) is a reliable solution to obtain real-time information during surgery and it has been applied in many different aspect of neurosurgery. In the last years, different ioUS modalities have been described: B-mode, Fusion Imaging with pre-operative acquired MRI, Doppler, contrast enhanced ultrasound (CEUS), and elastosonography...

BACKGROUND: The pre-surgical selection of thyroid nodules with indeterminate cytology (Thy 3 according to British Thyroid Association) after fine-needle aspiration biopsy (FNAB) is currently required in order to reduce unnecessary total thyroidectomy. The objective of our study was to use a surgical series of Thy 3 nodules to evaluate the predictive role of ultrasound elastosonography (USE) and contrast-enhanced ultrasonography (CEUS) in pre-surgical diagnoses of malignancy. SUBJECTS AND METHODS: We enrolled 63 patients with Thy 3 nodules in which cytological-histological correlation was available...

BACKGROUND: Ultrasound is as a noninvasive method commonly used in the work-up of thyroid nodules. This study aimed to evaluate the usefulness of sonographic and elastosonographic parameters in the discrimination of malignancy. PATIENTS AND METHODS: 150 thyroid nodules were evaluated by gray-scale, Doppler and elastosonography. The cytological analysis revealed that 141 nodules were benign and 9 were malignant. RESULTS: Orientation of the nodule was the only sonographic parameter associated with malignancy (p = 0...

BACKGROUND: The parotid gland is the mostly affected site among major salivary gland tumors in up to 85% of cases. Preoperative knowledge of the tumour nature is crucial since it influences the surgical procedure and patient's morbidity, especially the risk of facial nerve palsy. Ultrasonography is commonly used as the first line imaging modality for the salivary gland lesions. A pitfall is that the histologic pleomorphism often reflects an imaging pleomorphism.

The aim of this study was to investigate the diagnostic value of the Virtual Touch™ tissue quantification (VTQ) and elastosonography technologies in benign and malignant breast tumors. Routine preoperative ultrasound, elastosonography and VTQ examinations were performed on 86 patients with breast lesions. The elastosonography score and VTQ speed grouping of each lesion were measured and compared with the pathological findings. The difference in the elastosonography score between the benign and malignant breast tumors was statistically significant (P<0...

REVIEW
Teresa Rago, Paolo Vitti
Among several ultrasound patterns, thyroid nodule hypoechogenicity, spot microcalcifications, and an absent halo sign are used for predicting increased risk of thyroid malignancy. The predictive value of ultrasound, however, increases at the expense of its sensitivity, and malignancy is predicted with high specificity only when multiple ultrasound features are simultaneously present. Ultrasound features are important in determining the strength of the indication for carrying out fine needle aspiration. To this end, a system for standardization of ultrasound features (Thyroid Imaging Reporting and Data System) aids in establishing risk of malignancy...
