Evaluation of ultrasound transmission velocity and 3-dimensional radiology in different bone types for dental implantology: a comparative ex vivo stu…

2013

Objective To evaluate ultrasound transmission velocity (UTV) for assessment of mechanical bone quality, an ex vivo comparison of different bone types measured with UTV, 2-dimensional (2D) histomorphometry and with 3-dimensional (3D) radiology (cone-beam computerized tomography [CBCT], computerized microtomography [μCT]) was conducted. Study Design Clinical cortical, cancellous, and mixed bone (each n = 6) was measured via UTV (m/s), CBCT (white pixel/black pixel ratio [WP/BP]), μCT (bone volume/total volume [μBV/TV]), and histomorphometry (bone volume/total volume [hBV/TV]). UTV values were correlated with 2D-histomorphometry and 3D-radiologic results. Results For the cortical, cancellous, …

Is rectal disimpact always necessary in children with chronic constipation? Evaluation with pelvic ultrasound

2010

PURPOSE: The aim of study was to evaluate if pelvic ultrasound can be useful in managing children with chronic idiopathic constipation. METHODS: A total of 270 children with idiopathic chronic constipation were enrolled in the study. At baseline and at monthly checkups children were evaluated by clinical score and pelvic ultrasound (US). Patients have been divided in 2 groups, based on pelvic US results: group A with a rectal diameter >3 cm, group B with a rectal diameter <3 cm or rectum not visualized. Both groups were subsequently randomly divided in two subgroups (A1, A2, B1, B2) on the basis of the prescribed treatment (disimpaction for the first week and daily laxative or only daily la…

Giant area of transient hepatic attenuation difference, mimicking incidentaloma at liver ultrasound.

2010

Concurrent with recent advances in diagnostic imaging techniques, the incidental finding of liver tumors, or incidentalomas, is increasing in asymptomatic and healthy individuals [1]. A 56-year-old healthy man underwent an abdomen ultrasound for a clinical check-up. A diffuse bright liver echo-pattern (indicating a low-moderate grade steatosis) and an unusual image (diameter approximately 10 cm) in the VI–VII hepatic segment, characterized by a massive giant hypoechoic lesion with poorly defined margins and a near rounded hyperechoic area (diameter about 4 cm) in the context were found (Fig. 1). The ultrasonographer suspected an angioma as first diagnostic hypothesis; however the large hypo…

The association between coronary microvascular dysfunction and carotid intima media thickness in patients with cardiac syndrome X

2016

Abstract Objective The aim of this study was to evaluate in patients with cardiac syndrome X (CSX), using validated angiography indices, coronary blood flow and myocardial perfusion of the microcirculation to assess whether there is greater microvascular dysfunction in patients with increase of carotid intima media thickness (C-IMT), compared to those who do not have. Methods Our study was performed on a population 124 patients with CSX that underwent coronary angiography and carotid ultrasound. We divided the sample into two categories: patients with increase of C-IMT and those without increase. We calculated Gibson and Yusuf indices for each patient based on angiographic images, including…

Carotid intima media thickness and coronary atherosclerosis linkage in symptomatic intermediate risk patients evaluated by coronary computed tomograp…

2014

Background: There is a growing evidence that carotid intima media thickness (CIMT) is associated with coronary artery disease (CAD) and it should be used as a predictor of atherosclerotic burden of coronary arteries. However, these studies have been performed by using invasive coronary angiography (ICA) and in high-risk patients for CAD. The purpose of this study was to evaluate the correlation between CIMT by ultrasound and coronary atherosclerosis in symptomatic intermediate risk patients by coronary computed tomography angiography (CCTA). Methods: We enrolled 204 consecutive symptomatic patients (mean age: 61 +/- 10; men: 118) and intermediate risk for CAD. All patients underwent CIMT ul…

Role of high-resolution ultrasound in guiding treatment of idiopathic plantar fasciitis with minimally invasive techiniques

2007

The aim of this study was to assess the reliability of peri-fascial oedema as a sonographic criterion for selecting the most appropriate treatment (ultrasound-guided corticosteroid injection or ultrasound-guided extracorporeal shock wave therapy) of idiopathic plantar fasciitis (IPF).Sixty-four patients with a clinical diagnosis of unilateral refractory IPF, treated conservatively for at least 8 weeks, were studied with high-resolution ultrasound (HRUS). Pain intensity was evaluated with a visual analogue scale (VAS). HRUS was used to confirm IPF and identify the presence of peri-fascial oedema. Patients with an HRUS diagnosis of IPF were grouped according to the presence (A) or absence (B)…

Lung ultrasound in outpatients with heart failure: the wet‐to‐dry HF study

2021

The Nancy team is supported by the RHU Fight-HF, a public grant overseen by the French National Research Agency (ANR) as part of the second 'Investissements d'Avenir' programme (reference: ANR-15-RHUS-0004), by the French PIA project 'Lorraine Université d'Excellence' (reference: ANR-15-IDEX-04-LUE), the ANR FOCUS-MR (reference: ANR-15-CE14-0032-01), ERA-CVD EXPERT (reference: ANR-16-ECVD-0002-02), the Contrat de Plan Etat Lorraine IT2MP, and FEDER Lorraine. Aims: In ambulatory patients with chronic heart failure (HF), congestion and decongestion assessment may be challenging. The aim of this study is to assess the value of lung ultrasound (LUS) in outpatients with HF in characterizing deco…

Imaging processing for CT angiography of the cervicocranial arteries: evaluation of reformatting technique.

2007

Purpose. The aim of this study was to compare computed tomography angiography (CTA) sliding-thin-slab (STS) multiplanar reformatting (MPR), STS maximum intensity projection (MIP) and three-dimensional (3D) volume rendering (VR) reformatting techniques in the evaluation of cervicocranial arteries. Materials and methods. Twenty patients examined with multislice CT were included in this study. CTA images were reformatted as STS-MIP, STS-MPR and 3DVR in orthogonal planes and in the oblique-coronal plane. Images were evaluated in consensus by two radiologists, with a third radiologist to resolve discordances in grading image quality parameters. The Spearman correlation analysis was performed to …

Is Transcranial Magnetic Resonance Imaging-Guided Focused Ultrasound a Repeatable Treatment Option? Case Report of a Retreated Patient With Tremor Co…

2019

Introduction In recent years, transcranial Magnetic Resonance Imaging-guided Focused Ultrasound (tcMRgFUS) treatments for functional neurological disorders are giving a new thrust to the field of therapeutic brain lesioning. Objective To present the case of a patient affected by tremor combined with Parkinsonism who underwent a second tcMRgFUS thalamotomy because of relapsing tremor after a few months from the first tcMRgFUS treatment. Methods A 72-yr-old, right-handed man, came to our observation because of a disabling tremor affecting his upper limbs, refusing any invasive surgical procedure and already treated by tcMRgFUS left Vim thalamotomy. However, clinical benefit had brief duration…
