Incidentally discovered thyroid nodules: incidence, and greyscale and colour Doppler pattern in an adult population screened by real-time compound sp…

2006

Purpose. Our aim was to assess the incidence and ultrasound features of thyroid nodules in an adult population screened by means of high-resolution ultrasonography (HRUS) and to evaluate the contribution of real-time spatial compound sonography (CS) in terms of image quality. Materials and methods. A total of 704 consecutive patients (400 women, 304 men) without thyroid disease underwent HRUS and CS examination of the thyroid gland. Number, size, location, echotexture and colour Doppler pattern of detected nodules were assessed. Two radiologists also assessed image quality of the two techniques. Results. Seven hundred and eleven thyroid nodules (size range 0.18-4.1 cm; mean: 1.1 cm) were de…

Anatomical variations of the internal jugular vein: The role of ultrasonography

2014

Purpose: In many places, especially in emergency department, central venous catheter is still inserted using anatomical landmark guidance with a success rate up to 97.6% and complications up to 15%. This study was aimed to determine by the support of ultrasono-graphy (US) the anatomical variations of the internal jugular vein (IJV) in relation with other structures of the neck, such as the common carotid artery (CCA). Material and Methods: 830 patients requiring central vein catheterization (CVC) were in-cluded in the analysis. The position of the IJV in relation to the other structures of the neck was demonstrated by portable ultrasonography. Results: The mean diameter of IJV was 10.3 mm i…

Early detection of embryonic malformations by transvaginal and color Doppler sonography.

1994

A total of 834 women with uneventful pregnancies were followed prospectively until the 15th week of gestation by TVS to screen for early embryonic malformations. Twenty-eight embryonic anomalies were detected in this series (3.3%). The median gestational age at diagnosis was 11 (range, 8 to 15) weeks. Two neural tube defects were missed by early TVS screening. Two suspected abdominal wall defects were not confirmed by repeat mid-second trimester abdominal sonography representing 6.7% of all fetal malformations evident by 24 weeks of gestation. The sensitivity and specificity of TVS screening for fetal malformations in this series were 93.3 and 99.7%, respectively. In addition, the role of T…

Non-invasive diagnosis and grading of postsurgical endoscopic recurrence in Crohn's disease

2010

Abstract Non-invasive techniques aim to be an alternative to endoscopy in the assessment of postsurgical recurrence of Crohn's disease (CD). The object of this study was to evaluate the accuracy of abdominal ultrasonography (AUS) and 99m Tc-hexamethylpropylene amineoxime ( 99m Tc-HMPAO)-labelled leucocyte scintigraphy (LLS) compared with endoscopy in the diagnosis and grading of postsurgical recurrence of CD. Between January 2006 and May 2007, all patients with CD and resection with ileocolic anastomosis were included prospectively. Within three days they underwent an ileocolonoscopy, AUS with evaluation of bowel wall thickness and the presence of Doppler flow, and LLS. Forty patients who m…

CEUS LI-RADS: a pictorial review

2020

AbstractContrast-enhanced ultrasound (CEUS) greatly improved the diagnostic accuracy of US in the detection and characterization of focal liver lesions (FLLs), and it is suggested and often included in many international guidelines as an important diagnostic tool in the imaging work-up of cirrhotic patients at risk for developing hepatocellular carcinoma (HCC). In particular, CEUS Liver Imaging Reporting and Data System (LI-RADS) provides standardized terminology, interpretation, and reporting for the diagnosis of HCC. The aim of this pictorial essay is to illustrate CEUS features of nodules discovered at US in cirrhotic liver according to LI-RADS categorization.

Intestinal tuberculosis in a child living in a country with a low incidence of tuberculosis : a case report

2014

Background: Relatively common in adults, intestinal tuberculosis is considered rare in children and adolescents. The protean manifestations of intestinal tuberculosis mean that the diagnosis is often delayed (sometimes even for years), thus leading to increased mortality and unnecessary surgery. The main diagnostic dilemma is to differentiate intestinal tuberculosis and Crohn’s disease because a misdiagnosis can have dramatic consequences. Case presentation: A 13-year-old Caucasian, Italian female adolescent attended the Emergency Department complaining of abdominal pain, a fever of up to 38°C, night sweats, diarrhea with blood in stool, and a weight loss of about three kilograms over the p…

Carotid plaque detection improves the predictve value of CHA2DS2-VASc score in patients with non-valvular atrial fibrilation: The ARAPACIS Study

2017

Abstract Background and aims Vascular disease (VD), as assessed by history of myocardial infarction or peripheral artery disease or aortic plaque, increases stroke risk in atrial fibrillation (AF), and is a component of risk assessment using the CHA 2 DS 2 -VASc score. We investigated if systemic atherosclerosis as detected by ultrasound carotid plaque (CP) could improve the predictive value of the CHA 2 DS 2 -VASc score. Methods We analysed data from the ARAPACIS study, an observational study including 2027 Italian patients with non-valvular AF, in whom CP was detected using Doppler Ultrasonography. Results VD was reported in 351 (17.3%) patients while CP was detected in 16.6% patients. Ad…

Real-time ultrasonography in the otolaryngology office setting

1993

Over the past two decades, diagnostic ultrasonography has evolved into an extensively used noninvasive imaging modality. It plays a vital role in the disciplines of vascular surgery, cardiology, neonatology, pediatrics, ophthalmology, gynecology, and urology, to name a few, but it is in the field of obstetrics that this technology has been maximally used as an office procedure to evaluate the status of the fetus. In the evaluation of head and neck disorders, ultrasonography has been the subject of sporadic reports for the past 15 years.le3 However, except for the evaluation of thyroid masses,4 it has never been widely accepted in the United States as a diagnostic modality, and has taken a b…

The ultrasound microdubble contrast in the diagnosis and the decisional iter of the treatment of the traumatic spleen lesions

2006

To estimate our 3-year experience on the diagnosis and monitoring of the spleen traumatic lesions with the employment of ultrasound microbubbles contrast. From the 174 patients who were joints to our department in regimen of urgency for abdominal traumatic lesions, we have estimated 24 patiens including our criteria. The selected patients have been subordinate to the echographic examination with microbubbles contrast and to TC multi-detector (MDCT) with contrast with multiphasic technique. The echographic examination has evidenced 4 patients with abdominal fluid deposit without spleen parenchimal damage and 8 patients with morphofunctional alterations of the spleen. After the introduction o…
