Assessment of Liver Diseases Using a Deep-Learning Approach Based on Ultrasound RF-Data

The goal of this clinical trial is to test the performance of neuronal networks trained on ultrasonic raw Data (=radiofrequency data) for the assessment of liver diseases in patients undergoing a clinical ultrasound examination. The general feasibility is currently evaluated in a retrospective cohort. The main questions the study aims to answer are: * Can a neuronal network trained on RF Data perform equally good as elastography in the assessment of diffuse liver diseases? * Can a neuronal network trained on RF Data perform better than a neuronal network trained on b-mode images in the assessment of diffuse liver diseases? * Can a neuronal network trained on RF Data distinguish focal pathologies in the liver from healthy tissue? To answer these questions participants with a clinically indicated fibroscan will undergo: * a clinical elastography in Case ob suspected diffuse liver disease * a reliable ground truth (if normal ultrasound is not sufficient e.g. contrast enhanced ultrasound, biopsy, MRI or CT) in case of focal liver diseases, depending on the standard routine of the participating center * a clinical ultrasound examination during which b-mode images and the corresponding RF-Data sets are captured

One Cause of Heel Pain is Plantar Fasciopathy (PF). In Most Cases, a Heel Spur is Frequently Present Alongside PF. We Aim to Evaluate the Efficacy of Corticosteroid Injection and Radiofrequency Ablation, Along With Tissue Elasticity Assessed by Ultrasound, in Patients With Chronic Pain (≥6 Months).

Heel pain is common among adults. One cause of heel pain is plantar fasciopathy (PF). In most cases, a heel spur, a bony prominence that extends into the plantar fascia, is frequently present alongside PF. First-line treatments include pain-relieving drugs, home exercises, heel support peds, and physical therapy. However, some patients can't get relief from these therapies, and the pain persists beyond six months. This situation is referred to as refractory chronic PF. Local treatments applied via skin puncture such as anti-inflamtory injection and destruction of nerves carrying pain signals to brain are warranted in these cases. We aim to evaluate the efficacy of corticosteroid injection and radiofrequency ablation, along with tissue elasticity assessed by ultrasound, in patients with chronic pain (≥6 months). The goal of this clinical trial is to determine which treatment-corticosteroid injection or radiofrequency thermal thermocoagulation-is more effective for treating plantar fasciopathy in adults. It will also learn about the effects of the treatments on the properties of the heel tissue using ultrasound. The main questions it aims to answer are: Do corticosteroid injections and radiofrequency thermal thermocoagulation have the same efficacy on pain and functionality for both short- and long-term? Do corticosteroid injections and radiofrequency thermal thermocoagulation similarly affect heel tissue? The researchers will investigate which of the corticosteroid injection and radiofrequency thermocoagulation is more effective for

Transthoracic Shear-wave Ultrasound Elastography

This study aims to provide the information of tissue elasticity in different etiologies of pulmonary lesions and to validate the predictive value of shear-wave elastography in differentiating benign pulmonary lesions from malignant lesions.
