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...

Finding a soft tissue mass in the superficial regions is a common event in daily clinical practice. Correct management of the diagnostic process is crucial to avoid blunders. Diagnosis is posed by pathology, although both imaging and a better understanding of the cellular and molecular mechanisms play an important a role in the characterization, staging and follow-up of soft tissue masses. Cellular and molecular mechanisms can explain either the development of chemo-resistance and the underlying pre- and post-surgery metastasis formation...

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...

Over the years, ultrasound (US) has accumulated important evidence supporting its relevant role for the assessment of inflammatory processes of different rheumatologic diseases, as well as in the follow-up in assessing the response to different therapeutic approaches. This has been possible because of the increase in training, competency, and knowledge, as well as the rapid progress in the US technologies.Currently, some US machines can be equipped by sophisticated software modalities (i.e., 3-dimensional US, elastosonography, automated cardiovascular software, and fusion imaging) that can augment US traditional role as a safe, fast, and easy-to-perform modality and giving it new life and increased relevance in rheumatology...

The early diagnosis of prostate cancer (PCa) appears to be of vital significance for the provision of appropriate treatment programs. Even though several sophisticated imaging techniques such as positron emission tomography/computed tomography (PET/CT) and elastosonography (ES) have already been developed for PCa diagnosis, the diagnostic accuracy of these imaging techniques is still controversial to some extent. Therefore, a comprehensive meta-analysis in this study was performed to compare the accuracy of various diagnostic imaging methods for PCa, including 11C-choline PET/CT, 11C-acetate PET/CT, 18F-fluorocholine PET/CT, 18F-fluoroglucose PET/CT, transrectal real-time elastosonography (TRTE), and shear-wave elastosonography (SWE)...

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...
