Central venous access has traditionally been performed on the basis of designated anatomical landmarks. However, due to patients' individual anatomy and vessel pathology and depending on individual operators' skill, this landmark approach is associated with a significant failure rate and complication risk. There is substantial evidence demonstrating(More)
BACKGROUND AND AIM Cervical cancer has high incidence and mortality in developing countries. It is the only gynecological malignancy that is clinically staged. Staging at the time of diagnosis is crucial for treatment planning. After radiation therapy, clinical examination is limited because of radiation changes. An imaging method relatively unaffected by(More)
Contrast enhanced ultrasonography, using i.v. and/or oral/rectal contrast agents, represents a technical development of the US method, which has proved its applicability in the qualitative and quantitative assessment of the normal and pathological circulatory bed, as well as of the digestive lumen. The use of microbubbles and harmonics opens a new horizon(More)
Splanchnic aneurysms are rare conditions, with localization at the level of the gastroduodenal artery being encountered in only 1.5 % of the cases. Due to the high mortality risk, early detection and optimal treatment are required. We stress the importance of ultrasonography as a primary method of detection as well as the role of contrast-enhanced(More)
Ultrasound is often the first imaging procedure performed in the evaluation of individuals with suspected or known liver disease. Despite technical advances in ultrasound techniques, sonographic detection and evaluation of diffuse liver disease still remains difficult. This is due to the fact that diffuse liver disease does not always cause distortion of(More)
AIM To investigate contrast-enhanced ultrasound (CEUS) findings in portal venous system aneurysms (PVSAs). METHODS In this multi-center, retrospective, case series study, we evaluated CEUS features of seven cases of PVSAs that were found incidentally on conventional ultrasound in the period 2007-2013. Three Ultrasound Centers were involved (Chieti, Italy,(More)
Ultrasonography (US) is the essential imaging method in gallbladder examination being the most widespread and inexpensive technique. The method is indicated both in congenital and acquired disorders, inflammatory, tumoral, or degenerative pathology. Besides the basic technique (grey scale US), new sophisticated techniques exist: Doppler US, i.v. contrast(More)
Benign hepatic tumors are commonly observed in adults, but rarely reported in children. The reasons for this remain speculative and the exact data concerning the incidence of these lesions are lacking. Benign hepatic tumors represent a diverse group of epithelial and mesenchymal tumors. In pediatric patients, most benign focal liver lesions are inborn and(More)
Inflammatory myofibroblastic tumors (IMT) are rare benign lesions that may often be mistaken for malignancies due to their imaging resemblance. There are a limited number of case reports in the literature on the location at the level of the gallbladder. We present a case of IMT of the gallbladder that emphasizes the importance of conventional ultrasound as(More)
Shear wave elastography (SWE) has been developed to non-invasively estimate liver stiffness. Different techniques are available and they are described in detail in the EFSUMB guidelines on elastography. However, there are only a few published studies investigating normal ranges in healthy subjects by comparing different equipment and analysing influencing(More)
