Liver stiffness, a non-invasive marker of liver disease: a core study group report

2010

The ability to evaluate liver stiffness non-invasively in clinical practice by measuring transient elastography using FibroScan® has resulted in considerable interest and enthusiasm. A core study group, organized by the Italian Association for the Study of the Liver, has assessed the usefulness of FibroScan® in the diagnosis and management of liver disease in clinical practice. The group concluded that FibroScan® is a valuable, non-invasive technique and have developed a consensus report form for registering transient elastography results. In this article, we report the findings of the study group.

The severity of steatosis influences liver stiffness measurement in patients with nonalcoholic fatty liver disease

2015

In nonalcoholic fatty liver disease, the influence of severity of steatosis on liver stiffness measurement (LSM) is poorly studied and still debated. We assessed the impact of steatosis severity and its ultrasonographic (US) sign, severe bright liver echo pattern, on LSM values and on transient elastography accuracy for the diagnosis of liver fibrosis in a cohort of consecutive patients with nonalcoholic fatty liver disease. Patients (n = 253) were assessed by clinical, US, and histological (Kleiner score) features. Transient elastography was performed using the M probe. Among patients with low amounts of fibrosis (F0-F1 and F0-F2), median LSM values, expressed in kilopascals, were signific…

RUOLO DELL’ELASTOSONOGRAFIA E DELL’ENTERO-RM PER LA VALUTAZIONE DEL MESENTERE E DELLA PARETE INTESTINALE NEI PAZIENTI CON MORBO DI CROHN

2020

Purpose. To evaluate and compare the mesenteric and bowel wall changes during Crohn’s disease (CD) on ultrasonography (US) Strain Elastography (SE) and Enterography Magnetic Resonance Imaging (E-MRI). Methods. From July 2014 to September 2016, 35 patients with ileocolonoscopy diagnosis of CD were prospectively examined with E-MRI and in the same time with US and SE. Results. A total of 41 affected bowel segments and 35 unaffected bowel segments in 35 patients were evaluated. US-SE color-scale coding showed a blue color pattern in the fibrotic mesentery and bowel wall in 15 patients and a green color pattern in the edematous ones in 20 patients. The signal of the bowel wall and mesenteric fa…

US-Elastography for Breast Lesion Characterization: Prospective Comparison of US BIRADS, Strain Elastography and Shear wave Elastography

2020

 To evaluate the diagnostic performance of strain elastography (SE) and 2 D shear wave elastography (SWE) and SE/SWE combination in comparison with conventional multiparametric ultrasound (US) with respect to improving BI-RADS classification results and differentiating benign and malignant breast lesions using a qualitative and quantitative assessment. In this prospective study, 130 histologically proven breast masses were evaluated with baseline US, color Doppler ultrasound (CDUS), SE and SWE (Toshiba Aplio 500 with a 7-15 MHz wide-band linear transducer). Each lesion was classified according to the BIRADS lexicon by evaluating the size, the B-mode and color Doppler features, the SE qualit…

Accuracy of Transient Elastography in Assessing Fibrosis at Diagnosis in Naïve Patients With Primary Biliary Cholangitis: A Dual Cut-Off Approach

2021

Background & aims Liver fibrosis holds a relevant prognostic meaning in primary biliary cholangitis (PBC). Non-invasive fibrosis evaluation using vibration-controlled transient elastography (VCTE) is routinely performed. However, there is limited evidence on its accuracy at diagnosis in PBC. We aimed to estimate the diagnostic accuracy of VCTE in assessing advanced fibrosis at disease presentation in PBC. Approach & results We collected data from 167 consecutive treatment-naive PBC patients who underwent liver biopsy(LB) at diagnosis at six Italian centers. VCTE examinations were completed within 12 weeks of LB. Biopsies were scored by two blinded expert pathologists, according to Ludwig sy…

Noninvasive assessment of liver fibrosis in thalassaemia major patients by transient elastography (TE) - lack of interference by iron deposition.

2009

The correlation between liver stiffness, measured by transient elastography, liver fibrosis, using the histological METAVIR score, and iron overload, measured by atomic absorption spectrometry was evaluated in 56 homozygous-b-thalassaemics. Liver stiffness increased proportionally to liver fibrosis staging (r = 0Æ70; P > 0Æ001) independently of liver iron concentration (r = 0Æ01; P = 0Æ932). The area under the receiver-operating characteristic curve for prediction of cirrhosis was 0Æ997 (95% confidence interval [CI]: 0Æ925–1Æ000) with cut-off of 13 kPa with 100% sensitivity (95% CI: 69Æ0–100Æ0) and 95% specificity (95% CI: 84Æ2–99Æ3). Transient elastography is a reliable non-invasive tool f…

Deguna vārsta kustīguma kvantitatīvs novērtējums 

2018

Pamatojums: Deguna vārsts ir visšaurākais reģions visos augšējos elpceļos. Tā ir kustīgā deguna daļa, kas tiek uzskatīta par STARLING-rezistoru. Lai paplašinātu vai stabilizētu deguna vārstu, ir publicētas dažādas palīgierīces un metodes, taču indikācijas to izmantošanai ir balstītas vien uz ķirurgu personīgo pieredzi. Mērķis: Veikt objektīvu deguna vārsta lomas novērtējumu. Materiāli un metodes: Pētījumā tika iekļauti 30 brīvprātīgie, kuriem ar elastīgu tērauda elementu, fiksētu pie galvas lentes un aprīkotu ar deformācijas sensoru (strain gauge), tika precīzi izmērīta deguna laterālās sienas novirze tās dziļākajā punktā elpošanas laikā. Novirzes kalibrācija tika veikta ar speciālām kalibr…
