PURPOSE: To determine the accuracy of biplane transrectal ultrasonography (TRUS) plus ultrasonic elastosonography (UE) and contrast-enhanced ultrasonography (CEUS) in preoperative T staging after neoadjuvant chemoradiotherapy for rectal cancer. MATERIALS AND METHODS: Fifty-three patients with advanced lower rectal cancer were examined before and after neoadjuvant chemoradiotherapy with use of TRUS plus UE and CEUS and were diagnosed as having T stage disease. We compared ultrasonic T stages before and after neoadjuvant chemoradiotherapy and analyzed any changes...

To test the hypothesis that the lesional stiffness as measured by transvaginal elastosonography (TVESG) correlates with the extent of fibrosis in adenomyotic (AM) lesions, and thus TVESG can be used to diagnose AM, we conducted 2 studies. The first evaluated the relationship, if any, between lesional stiffness and lesional histology in 35 women with histologically confirmed AM in comparison with tissue stiffness in 11 control myometrial (CM) and 8 uterine fibroids (UFs) tissue samples. The second validated the relationship between lesional stiffness and the severity of dysmenorrhea and the amount of menses in AM patients by recruiting 112 patients diagnosed with AM, 67 with UF, and 130 controls...

The aim of the study is to screen the significant sonographic features by logistic regression analysis and fit a model to diagnose thyroid nodules. A total of 525 pathological thyroid nodules were retrospectively analyzed. All the nodules underwent conventional ultrasonography (US), strain elastosonography (SE), and contrast -enhanced ultrasound (CEUS). Those nodules' 12 suspicious sonographic features were used to assess thyroid nodules. The significant features of diagnosing thyroid nodules were picked out by logistic regression analysis...

Purpose: Peripheral nerves frequently travel close to the bone surface and are, therefore, prone to elastosonographic "bone-proximity" hardening artifacts. The impact of these artifacts on quantitative measurements of median nerve stiffness performed by shear wave elastosonography has not been explored. Our aim was to assess normal median nerve stiffness values at various locations. Materials and methods: Thirty-six healthy volunteers (24 women and 12 men) aged between 25 and 40 years were evaluated...

INTRODUCTION: Renal allograft biopsy is the gold standard for the detection of histological lesions of chronic allograft dysfunction. The identification of a noninvasive routine test would be desirable. Elastosonography is used to assess tissue stiffness according to viscosity, and no data are available on the use of point quantification shear-wave elastography (ElastPQ) for the evaluation of renal chronic lesions. RESEARCH QUESTION: To evaluate the feasibility of ElastPQ to assess cortical allograft stiffness and to determine the correlation of clinical, biological, and pathological factors with the diagnostic accuracy of kidney stiffness values in patients with histological lesions...

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...

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...

AIM: The aim of this research was to study and compare placental elasticity with acoustic radiation force impulse (ARFI) elastography in pre-eclamptic and normal pregnancies. METHODS: A total of 107 singleton pregnancies in the third trimester (38 healthy control subjects, 34 patients with gestational hypertension, and 35 pre-eclampsia patients) were included in the study. ARFI elastography was used to determine the placental elasticity in the three predetermined regions of the placenta (the fetal edge, maternal edge, and central part of the placenta)...

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...

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...
