PURPOSE: To develop and evaluate artificial intelligence (AI) algorithms for ultrasound (US) microflow imaging (MFI) in breast cancer diagnosis. MATERIALS AND METHODS: We retrospectively collected a dataset consisting of 516 breast lesions (364 benign and 152 malignant) in 471 women who underwent B-mode US and MFI. The internal dataset was split into training (n = 410) and test datasets (n = 106) for developing AI algorithms from deep convolutional neural networks from MFI...

PURPOSE: To evaluate the diagnostic yield of contrast-enhanced ultrasound (CEUS)-guided biopsy of retroperitoneal masses (RMs). MATERIALS AND METHODS: Between 2006 and 2023, 87 patients presented at our US center for biopsy of an RM. In all biopsies, CEUS was performed prior to the intervention. The technical success rate of biopsy, the presence of diagnostic tissue in solid tumor biopsy samples, the accuracy of the biopsy and the occurrence of post-interventional complications were evaluated...

PURPOSE: The use of tissue adhesive instead of a drain following mastectomy was a point of interest for many breast surgeons. Postoperative formation of multiple unusual sonographic lesions was observed in patients that underwent mastectomy with TissuGlu. The aim of this study was to describe the sonographic features of these lesions and, when possible, to examine them histologically. MATERIALS AND METHODS: This study includes 98 patients, 49 underwent mastectomy with the application of TissuGlu and 49 with drain insertion...

Purpose Ultrasound-guided puncture and punch biopsy pose a particular challenge in the training of ultrasound examination. These techniques should be learned and performed several times before being applied to the patient using a simulation model that is as realistic as possible. While the use of agar-agar-based models is extensively documented in the literature, there is a discernible gap in publications specifically addressing their use in punch biopsy and puncture. The aim was to develop a cost-effective model for the simulation of ultrasound-guided interventions...

Simulation-based training (SBT) is increasingly acknowledged worldwide and has become a popular tool for ultrasound education. Ultrasound simulation involves the use of technology and software to create a virtual training setting. Simulation-based training allows healthcare professionals to learn, practice, and improve their ultrasound imaging skills in a safe learning-based environment. SBT can provide a realistic and focused learning experience that creates a deep and immersive understanding of the complexity of ultrasound, including enhancing knowledge and confidence in specific areas of interest...

As an extension of the clinical examination and as a diagnostic and problem-solving tool, ultrasound has become an established technique for clinicians. A prerequisite for high-quality clinical ultrasound practice is adequate student ultrasound training. In light of the considerable heterogeneity of ultrasound curricula in medical studies worldwide, this review presents basic principles of modern medical student ultrasound education and advocates for the establishment of an ultrasound core curriculum embedded both horizontally and vertically in medical studies...

PURPOSE: Since handheld ultrasound devices are becoming increasingly ubiquitous, objective criteria to determine image quality are needed. We therefore conducted a comparison of objective quality measures and clinical performance. MATERIAL AND METHODS: A comparison of handheld devices (Butterfly IQ+, Clarius HD, Clarius HD3, Philips Lumify, GE VScan Air) and workstations (GE Logiq E10, Toshiba Aplio 500) was performed using a phantom. As a comparison, clinical investigations were performed by two experienced ultrasonographers by measuring the resolution of anatomical structures in the liver, pancreas, and intestine in ten subjects...

PURPOSE: Over the course of more than two years, an expert group of 9 professional societies has created the S2e guidelines for fracture sonography. This publication summarizes the key points regarding the individual indications. MATERIALS AND METHODS: A systematic literature search was performed in PubMed, Google Scholar, and the Cochrane Database of Systematic Reviews from 2000 to March 2021 with evaluation of the literature lists. Randomized controlled clinical trials, observational clinical trials, meta-analyses, and systematic reviews were included...

PURPOSE: Ultrasound (US) represents the primary approach for abdominal diagnosis and is regularly used to guide diagnostic and therapeutic interventions (INVUS). Due to possible serious INVUS complications, structured training concepts are required. Phantoms can facilitate teaching, but their use is currently restricted by complex manufacturing and short durability of the materials. Hence, the aim of this study was the development and evaluation of an optimized abdominal INVUS phantom...

PURPOSE: Complete resection of the affected tissue remains the best curative treatment option for liver-derived tumors and colorectal liver metastases. In addition to preoperative cross-sectional imaging, contrast-enhanced intraoperative ultrasound (CE-IOUS) plays a crucial role in the detection and localization of all liver lesions. However, its exact role is unclear. This study was designed to evaluate the clinical and oncological impact of using CE-IOUS in the surgical treatment of these diseases...

It is estimated that the problem of Chronic Pelvic Pain (CPP) may concern up to 24% of women. Unfortunately, very often, despite extensive diagnostics, the cause of CPP remains unknown. The pathophysiology of CPP could be explained to a large extent by the occurrence of Pelvic Venous Disorders (PVD). Although pelvic venography is still considered the gold standard for the diagnosis of PVD, non-invasive diagnostic imaging techniques seem to be instrumental in the initial identification of patients with PVD. This literature review aimed to analyse and evaluate the usefulness of non-invasive diagnostic imaging techniques like Transvaginal Ultrasonography, Transabdominal Ultrasonography, Magnetic Resonance and Computed Tomography in the diagnosis and identification of patients with PVD...

PURPOSE: We aimed to evaluate several quantitative methods to describe the diastolic notch (DN), and compare their performance in the prediction of fetal growth restriction. MATERIALS AND METHODS: Patients who underwent a placental scan at 16-26 weeks' gestation and delivered at between Jan 2016 and Dec 2020 were included. Uterine artery pulsatility index was measured for all of the patients. In patients with a DN, it was quantified using the notch index and notch depth index...

Purpose The aim of the study was to assess fetal ears in prenatal 3D ultrasound and compare ear surface patterns and measurements between fetuses with syndromes and healthy fetuses. Materials and Methods Our study is based on 3D ultrasound images of 100 fetuses between the 20th and 37th week of gestation. We compared 50 ears of fetuses with syndromes (syndrome group) to 50 gestational age-matched ears of healthy fetuses (control group). The syndrome group consisted of fetuses with Trisomy 21 (n=13), Trisomy 18 (n=9) and other syndromes (n=28)...

The CME review presented here is intended to explain the significance of pleural sonography to the interested reader and to provide information on its application. At the beginning of sonography in the 80 s of the 20th centuries, with the possible resolution of the devices at that time, the pleura could only be perceived as a white line. Due to the high impedance differences, the pleura can be delineated particularly well. With the increasing high-resolution devices of more than 10 MHz, even a normal pleura with a thickness of 0...
