Intestinal Ultrasound of Adult Small Bowel Intussusception Caused by a Polyp: A Case Report

Oleksii Dutchak, Maksym Zhaivoronok

Intestinal ultrasound may facilitate early diagnosis of adult small bowel intussusception and can directly demonstrate a pathological lead point such as an intraluminal polyp. In patients with nonspecific abdominal symptoms, this may expedite CT confirmation, support appropriate surgical referral, and improve diagnostic …

Correlation between ultrasound attenuation coefficient measurement (ACM) and MRI PDFF assessment for evaluating liver steatosis in MASLD

Maksym Zhaivoronok, Oleh Dynnyk, Nataliya Deresh, Oleh Shcherbina et autres

Metabolically associated steatotic liver disease (MASLD) is a prevalent and serious global health concern, affecting 20–40% of the population. Early detection and accurate quantification of liver steatosis (LS) are crucial for preventing disease progression[1]. Current imaging methods, including ultrasound (US), and magnetic …

Accuracy of the hepatorenal index with additional standardized acoustic depth assessment for steatotic liver disease diagnosis

Maksym Zhaivoronok, Oleh Dynnyk, Ludovico Abenavoli, Nazarii M. Kobyliak

Metabolic dysfunction–associated steatotic liver disease (MASLD) is the most common pathology among all chronic liver diseases. In the early stages, steatotic liver disease (SLD) has an asymptomatic clinical course, which makes it difficult to detect. Ultrasound (US) is a safe, noninvasive, first-line …
