Summary: Endoscopic ultrasound-guided pancreatic sampling is effective for the histopathological diagnosis of autoimmune pancreatitis and can help distinguish between AIP and pancreatic cancer. Recent advancements in needle biopsy methodologies and technologies have improved the diagnostic efficacy of this technique. The guidance provided in this study is expected to further advance the histopathological diagnosis of AIP using EUS-guided pancreatic sampling.

Summary: Endoscopic ultrasound fine needle aspiration (EUS-FNA) cytology is useful in the differentiation of pancreatic cysts, with higher sensitivity when the solid component is targeted. This study aimed to evaluate the diagnostic value of contrast-enhanced guided EUS-FNA (CH-EUS-FNA) in enhanced mural nodules and discrimination between different cysts. Results showed that mucinous cysts had higher arterial enhancement on contrast-enhanced endoscopic ultrasound (CH-EUS), and CH-EUS-FNA identified mucinous cysts and malignancy with high sensitivity and specificity. A comprehensive assessment of solid components using contrast-enhanced endoscopic ultrasound is important for the identification of malignant cysts.

Summary: The purpose of this study is to investigate the associations between enhancement patterns on CH-EUS and the aggressiveness and prognosis of PanNENs. The late-phase vascular-poor pattern on CH-EUS showed the highest sensitivity and specificity for aggressive PanNENs. CH-EUS is valuable for the diagnosis and prognosis prediction of PanNENs.

Summary: The aim of this study was to assess the diagnostic value of contrast-enhanced harmonic endoscopic ultrasound (CH-EUS) for pancreatic metastases. The results showed that vascularity assessments on conventional EUS or CH-EUS are similar for pancreatic metastases of different origin. However, EUS tissue acquisition remains mandatory for the diagnosis.

Summary: By comparing the contrast-enhanced ultrasound (CEUS) and contrast-enhanced computed tomography (CECT) images, this study retrospectively collected data from six patients who were histopathologically confirmed to have hepatic angiosarcoma (HA). The study describes the imaging appearances of HA and analyzes the imaging characteristics from the perspective of histopathology and tumorigenesis. This study includes the largest number of histopathologically confirmed HA patients who received CEUS examinations to date.

Summary: This study aimed to explore the value of conventional ultrasound (CUS) and contrast-enhanced ultrasound (CEUS) radiomics in diagnosing breast cancer and predicting its molecular subtype. The CUS combined with CEUS model showed higher accuracy than the CUS model. The CUS radiomics model had varying accuracy in predicting different molecular subtypes, and the CEUS video improved the predictive performance of the CUS radiomics model.

Summary: Different CEUS enhancement modes were observed between benign and malignant SPLs, providing supplementary information for the differential diagnosis of SPLs in existing imaging diagnostic methods. There were statistically significant differences in perfusion pattern, degree of enhancement, and vascular signs between the two groups, with distinct features identified for each group. Homogeneity and necrosis did not show statistically significant differences between the benign and malignant groups.

Summary: Contrast-enhanced ultrasound plays a crucial role in the diagnosis, staging, and post-treatment follow-up of breast cancer. It is highly accurate in differentiating benign and malignant lesions, has significant implications in axillary staging, and can predict the response to treatment. CEUS is a valuable addition to breast ultrasound as a high-performance, non-irradiating imaging method.

Summary: Abdominal ultrasound is the preferred method in many clinical situations, with the use of B-mode imaging and conventional Doppler techniques. New technologies such as contrast-enhanced ultrasound, elastography, and fat quantification allow for multimodal characterization of organs and tissue structure using panoramic imaging, 3D techniques, and image fusion. The development of small portable devices expands the spectrum of sonographic diagnostics. This review provides an overview of current ultrasound technology based on published evidence and guidance for quality assurance.

Summary: Focal liver lesions (FLL) can be detected by various imaging techniques, and further characterization is necessary. Contrast-enhanced ultrasound (CEUS) and magnetic resonance imaging (MRI) are commonly used for this purpose. Ultrasound elastography has shown potential for detecting liver fibrosis and cirrhosis, but its use in differentiating malignant and benign liver tumors is not well-established. This review provides an overview of the current data on the utility and performance of ultrasound elastography for characterizing FLL.

Summary: Simulation has proven to be beneficial in clinical learning, speeding up the learning process and boosting learner confidence. The use of simulators in ultrasound education is explored in a state of the art paper by the WFUMB. The paper discusses different types of simulators, their requirements, technical aspects, and clinical applications. Despite being in its early stages, ultrasound simulation offers a wide range of training opportunities and has the potential for broader ultrasound education in healthcare.

Summary: Emergency Medicine Point-of-Care Ultrasound (EMPoCUS) is a widely accepted and cost-effective concept, but its rapid growth has presented challenges in terms of quality assurance and education standards. There is a lack of clear outcome measures for EMPoCUS skills, leading to a concern that the current approach may not adequately reflect training objectives. To address these issues, this position paper aims to establish central standards for European EMPoCUS stewardship based on a critical review of the current situation.

Summary: Intrapancreatic metastases are rare and can occur simultaneously or years after the initial diagnosis. Sonography and endosonography with contrast enhanced techniques are helpful in differential diagnosis. Renal cell carcinoma is the most common solitary metastasis with good prognosis after surgery. The primary tumor determines the further treatment, confirmed by endosonographic guided sampling for immunohistological examination.

Summary: The diagnostic capabilities of ultrasound go beyond evaluation of the pleural space and lungs. Ultrasound can accurately differentiate unclear mass lesions of the chest wall through additional techniques such as color Doppler imaging, contrast-enhanced ultrasound, and ultrasound-guided biopsy. It has a complementary function in imaging mediastinal pathologies, guiding percutaneous biopsies, and verifying endotracheal tube positioning in emergency medicine. Diaphragmatic ultrasound is increasingly important for assessing diaphragmatic function in long-term ventilated patients.

Summary: This study investigated the diagnostic value of resistance index (RI) in differentiating focal liver lesions. The results showed that the RI value was significantly lower in benign lesions compared to malignant lesions. In hepatocellular carcinoma, the RI value of intrahepatic cholangiocarcinoma was significantly lower than that of hepatocellular carcinoma lesions. Furthermore, the RI value was lower in large hepatocellular carcinoma lesions compared to small lesions. By using an RI value of 0.615 as a cutoff, the sensitivity, specificity, positive predictive value and negative predictive value were determined. This study concluded that color Doppler ultrasound examination and the RI parameter are valuable in differentiating malignant and benign liver tumors.
