PURPOSE:  To prospectively assess liver fibrosis with two-dimensional shear wave elastography (2D-SWE) in patients with chronic hepatitis B (CHB) and to compare the performance of this modality with that of serum indices using Scheuer scoring from liver biopsies as the reference standard. MATERIALS AND METHODS:  123 patients with CHB underwent 2D-SWE measurements and serological tests between April 2016 and February 2018. The 2D-SWE and serum indices in the diagnosis of liver fibrosis were assessed using receiver operating characteristic (ROC) analyses...

BACKGROUND:  Transient elastography-based liver stiffness value (TE-LSV) has been studied for the diagnosis of portal hypertension. Liver stiffness is influenced by the disease etiology. We aimed to perform a meta-analysis to determine the performance of TE-LSV for diagnosing portal hypertension in patients with alcoholic liver disease (ALD). METHODS:  We searched PubMed, Web of Science, Ovid and Cochrane library. A bivariate model was used to compute sensitivity and specificity...

An interdisciplinary task force of European experts summarizes the value of gastrointestinal ultrasound (GIUS) in the management of acute appendicitis and diverticulitis. Based on an extensive literature review, clinical recommendations for these highly common diseases in visceral medicine are presented.In patients with acute appendicitis, preoperative sonography has been established as a routine procedure in most European countries for medical and legal reasons. Routine sonography in these patients may reduce the rate of unnecessary surgery by half...

2 D shear wave elastography (2D-SWE) is the latest evolution of elastography techniques and allows real-time quantitative assessment of the medium stiffness. The aim of this review is to identify, describe, explain and illustrate some technical restrictions and artifacts in 2D-SWE. Encountered artifacts and technical restrictions may be categorized according to acquisition technique, medium, or operator: · Acquisition technique: B-mode & SWE entanglement, transducer frequency, posterior elastographic shadowing artifact, mirrored elastogram artifact, "vertical striped" artifact, resolution limits in SWE, non-equivalence of elastographic devices...

The miniaturization of ultrasound equipment in the form of tablet- or smartphone-sized ultrasound equipment is a result of the rapid evolution of technology and handheld ultrasound devices (HHUSD). This position paper of the European Federation of Societies in Ultrasound and Medicine (EFSUMB) assesses the current status of HHUSD in abdominal ultrasound, pediatric ultrasound, targeted echocardiography and heart ultrasound, and we will report position comments on the most common clinical applications. Also included is a SWOT (Strength - Weaknesses - Opportunities - Threats) analysis, the use for handheld devices for medical students, educational & training aspects, documentation, storage and safety considerations...

PURPOSE:  Artifacts may be part of any 3D sonographic examination during pregnancy and can disturb a routine diagnostic procedure, even simulate fetal malformation. The aim of this study was to classify the artifacts in different types according to their appearance. MATERIALS AND METHODS:  A total of 2349 healthy fetuses examined during the last five years was included in this study. The observed artifacts have been grouped into 6 different types according to their appearance: 1...

PURPOSE:  Altered cerebral hemodynamics are involved in changes in head biometry in fetuses with congenital heart disease (CHD). We compared head growth in different CHD groups with published normative values and investigated whether CHD groups differ from each other in terms of head circumference (HC) development over gestational age (GA). MATERIALS AND METHODS:  Retrospective cohort study consisting of 248 CHD fetuses. Subgroups were generated according to the expected ascending aorta oxygen saturation: Low placental blood content (BC) and therefore low oxygen delivery to the brain (group 1: n = 108), intermediate placental and systemic BC due to intracardiac mixing of blood (group 2: n = 103), high placental BC (group 3: n = 13) and low placental BC and low oxygen delivery to the brain without mixing of blood (group 4: n = 24)...

PURPOSE:  The aim of our retrospective evaluation was to compare the outcome of patients with prenatal and postnatal diagnosis of Tetralogy of Fallot (TOF) and to analyze prenatal echocardiographic parameters predicting intervention within 30 days postnatal. MATERIALS AND METHODS:  We evaluated 142 patients in our pediatric heart center and prenatal diagnosis center and prenatal practice Praenatal plus in Cologne between 01/08 - 06/16. RESULTS:  Within the prenatal diagnosis group, 6/74 fetuses (8...

INTRODUCTION:  Lung ultrasound (LUS) has a high diagnostic accuracy for identifying frequent conditions in the post-operative phase after lung transplantation (LTx). This study aimed to investigate the feasibility and clinical ability of LUS to identify pulmonary complications such as pleural effusions and pneumonias in the early postoperative phase after LTx. METHODS:  A prospective cohort study of lung transplant recipients who consecutively underwent single LTx (SLTx) or double LTx (DLTx) at the National Lung Transplantation Center in Denmark from May 1 to October 31, 2015 was conducted...

OBJECTIVE:  To evaluate the association of sonographic fetal biometry (sonographic head circumference (soHC), sonographic abdominal circumference (soAC), estimated fetal weight (EFW)) with mode of delivery and adverse perinatal outcome. METHODS:  Singleton pregnancies with a gestational age ≥ 37 weeks and an ultrasound examination with complete biometric parameters within 7 days before delivery were retrospectively included. The association between soHC, soAC, EFW and fetal (5-min Apgar < 7, pH < 7...

OBJECTIVE:  The timing of delivery for women affected by gestational diabetes (GDM) is still controversial. Good clinical practice often suggests offering induction of labor at term in order to reduce the complications associated with this condition, while recent evidence supports expectant management. Fetal Doppler parameters represent a validated tool for testing fetal well-being at term and can select pregnancies that need increased surveillance. The aim of the present study was to evaluate the role of fetal Doppler parameters at term for the prediction of pregnancy outcomes in patients affected by GDM...

PURPOSE:  To evaluate the ability of a new ultrasound (US) method based on sound speed estimation (SSE) with respect to the detection, quantification, and grading of hepatic steatosis using magnetic resonance (MR) proton density fat fraction (PDFF) as the reference standard and to calculate one US fat index based on the patient's SSE. MATERIALS AND METHODS:  This study received local IRB approval. Written informed consent was obtained from patients. We consecutively included N = 50 patients as the training cohort and a further N = 50 as the validation cohort who underwent both SSE and abdominal MR...

PURPOSE:  The purpose of this study was two-fold: (1) To determine how the number of ultrasound scans a trainee has completed predicts the trainee's diagnostic accuracy when performing transvaginal ultrasound examinations, and (2) to examine the utility of simulation-based assessment of ultrasound competence for determining readiness for independently performing examinations. MATERIALS AND METHODS:  101 OB/GYN trainees were surveyed regarding their clinical experience and the number of scans they had completed...
