Transcranial ultrafast ultrasound localization microscopy of brain vasculature in patients
March 15, 2021 — Nature Biomedical Engineering Abstract Changes in cerebral blood flow are associated with stroke, aneurysms, vascular cognitive impairment, neurodegenerative diseases and other pathologies. Brain angiograms, typically performed via computed tomography or magnetic resonance imaging, are limited to millimetre-scale resolution and are insensitive to blood-flow dynamics. Here we show that ultrafast ultrasound localization […]

Contrast echocardiography facilitates appropriate management of hospitalized patients with coronavirus disease 2019 (COVID-19) and suspected right ventricular masses: case series
March 10, 2021 — European Heart Journal Abstract Background Coronavirus disease 2019 (COVID-19) infection is associated with a coagulopathy with high incidence of venous thrombo-embolism. However, bleeding risk is also significant, causing difficulty in initiating and adjusting anticoagulation therapy in case of suspected thrombi. Cardiac masses can be challenging to be identified properly in the context of […]
An Update on the Pediatric CEUS Registry on Behalf of the “EFSUMB Pediatric CEUS Registry Working Group”
March 9, 2021 — EFSUMB Abstract The European Federation of Ultrasound in Medicine and Biology (EFSUMB) created the “EFSUMB Pediatric Registry” (EFSUMB EPR) with the purpose of collecting data regarding the intravenous application of pediatric contrast-enhanced ultrasound (CEUS). The primary aim was to document the current clinical practice and usefulness of the technique and secondarily […]
Molecular imaging of orthotopic prostate cancer with nanobubble ultrasound contrast agents targeted to PSMA
February 25, 2021 — Sci Rep Abstract Ultrasound imaging is routinely used to guide prostate biopsies, yet delineation of tumors within the prostate gland is extremely challenging, even with microbubble (MB) contrast. A more effective ultrasound protocol is needed that can effectively localize malignancies for targeted biopsy or aid in patient selection and treatment planning […]

February 24, 2021 — Dovepress Abstract Objective: To assess the clinical value of contrast-enhanced ultrasound (CEUS) technology in predicting axillary lymph nodes status before surgery, and to explore the feasibility of sentinel lymph nodes (SLNs) localization guided by CEUS combined with 125I implantation for breast cancer. Methods: From August 2017 to February 2019, 115 patients […]
Contrast-Enhanced vs Conventional Endoscopic Ultrasound for Diagnosis of Pancreatic Lesions
February 22, 2021 — Gastroenterology Advisor By Brandon May In this multicenter Korean trial, 240 consecutive patients (mean age, 67.30 years) with solid pancreatic lesions were randomly assigned to undergo either CEH-EUS (n=120) as participants in the interventional group or only conventional EUS (n=120) as participants in the control group. Researchers compared CEH-EUS-guided fine needle […]
FDA approves packaging for Bracco's Lumason agent
February 22, 2021 — AuntMinnie.com Bracco is set to introduce a 20-vial package of its Lumason ultrasound contrast agent following clearance by the U.S. Food and Drug Administration (FDA). The new packaging of Lumason (sulfur hexafluoride lipid-type A microspheres) contrast is a good option for the environmentally conscious and better from the point of view […]
Contrast-enhanced ultrasound of the pediatric brain
February 18, 2021 — Pediatric Radiology Abstract Brain contrast-enhanced ultrasound (CEUS) is an emerging application that can complement gray-scale US and yield additionalinsights into cerebral flow dynamics. CEUS uses intravenous injection of ultrasound contrast agents (UCAs) to highlight tissueperfusion and thus more clearly delineate cerebral pathologies including stroke, hypoxic–ischemic injury and focal lesions suchas tumors […]
