Percutaneous ultrasound guided radiofrequency and microwave ablation in the treatment of hepatic metastases. A monocentric initial experience.

Percutaneous radiofrequency (RFA) and microwave ablation (MWA) are currently the best treatment options forpatients with liver metastases (LM) who cannot undergo a liver resection procedure. Presently, few studies have evaluated theefficacy of tumor ablation in beginner's hands but none at all in hepatic metastasis. Our aim was to report the initial experiencewith ultrasound as a tool to guide tumor ablation in a low volume center with no experience in tumor ablation.

Is the presence of echo-rich periportal cuffing in the liver indicator for abdominal inflammation in pediatric patients?

Hyperechoic/echo-rich periportal cuffing (ErPC) is defined as an increase in echogenicity relative to the adjacentliver parenchyma. Thickening in the periportal area may occur with proliferation of bile ducts, hemorrhage, oedema, fibrosis,inflammatory changes or a combination of these. The aim of this study is to determine which intraabdominal inflammatory diseases are associated with the presence of ErPC in the pediatric population and to calculate the sensitivity and specificity of this finding.

Histopathological and Tumor Characteristics Associated with False Negative Axillary Ultrasonography Results in Breast Cancer.

As the false-negative rates of axillary ultrasonography (AUS) (21%-48%) are not optimal, the demand for axillary surgery remains even if AUS is negative. The aim of this study is to determine the histopathological and tumor characteristics associated with false-negative AUS results.

This study's aim is to present the specific ultrasonography (US) findings of a series of urachus anomalies.

EFSUMB Gastrointestinal Ultrasound (GIUS) Task Force Group: Celiac sprue and other rare gastrointestinal diseases ultrasound features.

Transabdominal gastrointestinal ultrasound (GIUS) is unique in its capacity to examine the bowel non-invasively and in its physiological condition, including extra-intestinal features such as the splanchnic vessels, mesentery, omentum and lymph nodes- even at the bedside. Despite this, and its extensive documentation for its usefulness, it has only been fully implemented in a few European countries and expert centres. Therefore, the European Federation of Societies for Ultrasound in Medicine and Biology (EF...

General advice in ultrasound based elastography of pediatric patients.

Ultrasound elastography including transient elastography (TE), point shear wave elastography, (pSWE) and two (three)- dimensional shear wave elastography (2D-SWE) have been introduced mainly for the evaluation of the liver. All the techniques are also feasible for the examination of spleen, whereas pSWE and 2D-SWE can be used for the assessment of the pancreas, kidney, gastrointestinal tract and other organs. Strain elastography also plays a role for non-liver applications. The aim of the current report is ...

Real-Time Elastography in the diagnosis of prostate cancer: a systematic review.

To evaluate the diagnostic accuracy of real-time elastography as a method for detecting prostate cancer.

The role of imaging techniques in the diagnosis, staging and choice of therapeutic conduct in pregnancy associated breast cancer.

Breast cancer diagnosed during pregnancy is at increasing incidence due to the increased frequency of obesity, the postponement of the first pregnancy to later decades of life and the advances of diagnostic techniques. Clinical and imaging diagnosis is difficult during gestation due to adaptive changes of the maternal organism , the mammary glads in particular. Furthermore, the therapeutic approach is limited both by the possible side effects on the fetus and by the skepticism of the couple over these thera...

Budd-Chiari syndrome - various etiologies and imagistic findings. A pictorial review.

Budd Chiari syndrome defines an obstruction of the hepatic venous outflow. Primary causes include pro-coagulant states resulting in venous thrombosis, while secondary Budd Chiari syndrome appears in conditions associated with extrinsic compression of the hepatic veins or tumor invasion. Clinical presentation is greatly varied, from incidentally discovered asymptomatic thrombosis to fulminant liver failure due to hepatic congestion. Abdominal ultrasonography is the key diagnostic tool of Budd Chiari syndrome...

Sonoanatomy revisited: the long thoracic nerve.

The long thoracic nerve (LTN) arises from the C5, C6 and C7 roots and innervates the serratus anterior muscle. Scapular winging is the landmark manifestation of LTN neuropathy and may develop after an accidental injury during selective cervical nerve root or inter-scalene brachial plexus blocks. Although its sonoanatomy has been described in the previous literature, how to gradually identify the entire nerve course has rarely been discussed. In this regard, the present paper aims to elaborate the scanning m...

Imaging appearance and role of CEUS of high flow priapism. A case report.

High flow priapism caused by perineal trauma is a relatively rare disorder. Early diagnosis represents a mandatory condition for the therapeutic resolution. Ultrasound examination is affordable and a within reach method for diagnosis also in an emergency context. We present the case of a 56-year-old male patient with traumatic priapism which was subsequently investigated by contrast-enhanced ultrasound and shear wave elastography. This may be one of the first cases presented in the literature.

Splenogonadal fusion evaluation using Contrast Enhanced Ultrasound and Elastography. A case report.

We present the case of splenogonadal fusion in a 53-year-old male patient assessed by ultrasound and MRI, confirmed by pathologic examination. In addition to B-mode and colour-coded Doppler ultrasound, shear wave elastography and CEUS were performed and are presented in detail. Splenogonadal fusion is a rare congenital anomaly presumably caused by an abnormal attachment of splenic tissue to the gonad during gestation. Diagnosis is challenging for clinicians and in unclear cases splenogonadal fusion might ca...

Can ultrasonography be useful in the diagnosis of urethral disorders of female-to-male transsexuals?

Sonourethrography (SUG) is one of the basic imaging tools in the diagnosis of male anterior urethral strictures. So far, no one has described the use of this examination in transgender patients after "female-to-male" operation. Based on the presented case, we describe ultrasonographical features of the construction of a neophallus and offer information allowing a more accurate evaluation of urethral disorders in this group of patients.

Musculoskeletal ultrasound versus MRI of the hands in healthy subjects - a pilot study.

High resolution imaging methods detect a spectrum of inflammatory-like and structural modifications at joint and tendon level in healthy subjects. The knowledge of their extent and degree is important when subclinical disease activity (implying therapy reassessment) must be differentiated from normality. Musculoskeletal ultrasound (MSUS) evaluation may be challenging even for experts when borderline or low grade lesions are present. Our objective was to analyse the frequency of inflammatory-like lesions...
