The aim of this retrospective study was to analyze contrast-enhanced ultrasound (CEUS) features of histologically proven f-HCC in comparison to benign focal nodular hyperplasia (FNH). Materials & Methods […]
Building better bubbles for ultrasound could enhance image quality, facilitate treatments
May 26, 2021 – By National Institute of Biomedical Imaging and Bioengineering Read full text at: https://doi.org/10.1021/acsnano.0c09701 Newswise — Ultrasound is a non-invasive technique that uses sound waves to either generate images of tissues inside of the body, or to interact with tissues as a therapeutic tool – to break up gallstones, increase blood flow, […]
Contrast-Enhanced Ultrasonography–Based Hepatic Perfusion for Early Prediction of Prognosis in Acute Liver Failure
May 26, 2021 – Hepatology Abstract Background and Aims Acute liver failure (ALF) is a rare but dramatic clinical syndrome characterized by massive hepatic necrosis leading to multiorgan failure. It is difficult to predict the outcomes in patients with ALF using existing prognostic models. We aimed to analyze hepatic perfusion using contrast-enhanced ultrasound and Doppler […]
Establishment of a Diagnostic Method for Pelvic Sentinel Lymph Node Metastasis by Contrast-Enhanced Ultrasound in Uterine Cancer
May 26, 2021 — Ultrasound in Medicine and Biology Abstract This study investigated the usefulness of conventional ultrasound (US) and contrast-enhanced ultrasound (CEUS) in distinguishing metastasis of pelvic sentinel lymph nodes (SLNs) in patients with gynecological cancer. We examined 74 SLNs of patients with endometrial cancer (n = 26) and cervical cancer (n = 11). Patients underwent US and […]
