Machine learning analysis of contrast-enhanced ultrasound (CEUS) for the diagnosis of acute graft dysfunction in kidney transplant recipients.

Aim: The aim of the study was to develop machine learning algorithms (MLA) for diagnosing acute graft dysfunction (AGD) in kidney transplant recipients based on contrast-enhanced ultrasound (CEUS) analysis of the graft.Materials and methods: This prospective study involved 71 patients with kidney transplant undergoing CEUS during follow-up. AGD wasdefined as an increase in serum creatinine levels of at least 25% compared to the baseline of the last three months.

Contrast-enhanced ultrasonography in the initial evaluation of the kidney graft function: a pilot study.

Aim: Our study aimed to assess the usefulness of contrast-enhanced ultrasound (CEUS) in the initial evaluation of the graft function.

Materials And Method: A cross-sectional study was conducted in the early postoperative period on patients with kidney transplantation, between September 2017 to November 2018. Two groups of patients were investigated; delayed graft function (DGF) and early graft function (EGF).

Shear-Wave Elastography Variability Analysis and Relation with Kidney Allograft Dysfunction: A Single-Center Study.

Shear-wave elastography (SWE) showed the absence or presence of significant differences among stable kidney allograft function and allograft dysfunction. We evaluated the variability of kidney allograft stiffness in relation to allograft dysfunction, respectively, in terms of a correlation of stiffness with patients' characteristics. A single-center prospective study on patients who had undergone renal transplantation was conducted between October 2017 and November 2018.

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.

Evaluation of the pancreatic tumors by transabdominal Shear Wave Elastography: preliminary results of a pilot study.

Aim: To identify the mean values of Shear Wave Elastography (SWE) in pancreatic neoplasms.

Material And Method: This pilot case-control study was conducted in a tertiary care setting and data were collected in a prospective manner. Thirty-three subjects were included and divided into two groups: 18 healthy subjects and 15 patients with pancreatic neoplasm, from which 14 patients were diagnosed with adenocarcinoma and one with intraductal papillary mucinous neoplasia.

The pursuit of normal reference values of pancreas stiffness by using Acoustic Radiation Force Impulse (ARFI) elastography.

Aim: The purpose of this study is to evaluate pancreatic stiffness by ARFI abdominal elastography. In the current literature, there are relatively few studies that have assessed the clinical utility of this technique.

Material And Method: A number of 37 healthy subjects were included.

Ultrasonography of the biliary tract - up to date. The importance of correlation between imaging methods and patients' signs and symptoms.

Ultrasonography is generally accepted and performed as a first choice imaging technique in patients with jaundice. The method allows the discrimination between cholestatic and mechanical jaundice. The existing procedures are multiple: gray scale, Doppler, i.

Ultrasound in the examination of the gallbladder - a holistic approach: grey scale, Doppler, CEUS, elastography, and 3D.

Ultrasonography (US) is the essential imaging method in gallbladder examination being the most widespread and inexpensive technique. The method is indicated both in congenital and acquired disorders, inflammatory, tumoral, or degenerative pathology. Besides the basic technique (grey scale US), new sophisticated techniques exist: Doppler US, i.
