NCT ID: NCT06317181 Not yet recruiting - Liver Diseases Clinical Trials

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

LivSPECTRUS
Start date: April 2024
Phase: N/A
Study type: Interventional

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

NCT ID: NCT06193707 Not yet recruiting - Breast Carcinoma Clinical Trials

Intelligent Remote Intervention for High-risk Breast Cancer Populations

Start date: January 2024
Phase: N/A
Study type: Interventional

The goal of this clinical trial is to compare the effects of modern remote health intervention regime with traditional in-person intervention strategies for high-risk breast cancer groups that with BI-RADS 3 or higher nodules. The main questions it aims to answer are: - Can the remote health intervention be more effective in slowing down the progression of breast nodules than the traditional in-person intervention? - Can the remote health intervention be more effective in minimizing the deterioration of the disease and reducing the risk of death in patients than the traditional in-person intervention? - Can the knowledge, belief and behavioral change of breast nodule population improve after receiving remote health intervention compared with traditional health management model? Participants will be divided into 2 groups, the Experimental group and the Control group. Participants in the Experimental group will be offered with modern remote interventions for 2 years, as describe below: - Teleconsultations: This involves using video calls, or phone calls once a month to connect patients for consultations, follow-ups, and discussions about conditions and symptom management. - Remote Monitoring and Wearable Devices: Wearable devices and remote monitoring tools like Infrared Breast Temperature Detector and Dynamic blood pressure detector will be used once a week to track patients' vital signs and symptoms remotely. - Mobile Applications: Specialized mobile apps will be used to provide a platform for patients to access educational materials, track their progress, manage management schedules, record symptoms, and connect with support groups or online communities. - Educational Platforms and Remote Health Education: Online platforms and resources provide educational materials about breast cancer, treatment options, potential side effects, lifestyle adjustments, and overall wellness. These resources empower patients by providing comprehensive information. Participants in the Control group will be offered with traditional strategies provided in the 'Breast Cancer Screening Guideline for Chinese Women': Ultrasound follow-up review is recommended no less than 3 to 6 months later. If there is no change at 2-year follow-up, it can be downgraded to BI-RADS 2; if there is suspicious change in the lesion during follow-up, biopsy should be considered to clarify the nature of the pathology.

COOLEY
Start date: June 1, 2024

The Relationship Between Upper Extremity Explosive Power and Trunk Muscles in Volleyball Players

Start date: October 26, 2023
Phase:
Study type: Observational [Patient Registry]

Volleyball is an interval sport involving consecutive aerobic and anaerobic loads. Strength training based on explosive movements can improve performance in the upper extremities. Strength performance has an important place in this sport. Trunk stabilization is defined as 'proximal stability for distal mobility'. Disorder in any segment of the kinetic chain model will affect the quality of movement in the lower and upper segments.The aim of this study is to examine the relationship between the morphological features of the transversus abdominis, lumbal multifidus (L4-5), internal external oblique muscles, and the anaerobic power of the upper extremity and shoulder girdle functionThis study was designed as a cross-sectional. They will consist of 30 volleyball players between 14-30 years of age. Muscle morphological features of the participants by ultrasound; explosive strength will be evaluated by Medicine Ball Throw test, functional evaluation will be evaluated by Closed Kinetic Chain Upper Extremity Endurance test.

NCT ID: NCT05498987 Not yet recruiting - Ultrasonography Clinical Trials

Ultrasound Achilles Tendon Assessment

Start date: May 14, 2023
Phase: N/A
Study type: Interventional

448kilohertz capacitive resistive monopolar radiofrequency is a novel technique in physiotherapy and its usefulness and clinical relevance is still to be investigated at both clinical practice and also in performance. Current studies show promising results in different musculoskeletal disorders, however there no studies in the assessment of quality soft tissue in sporty population after the used of this technique.

NCT ID: NCT05036460 Not yet recruiting - Ultrasonography Clinical Trials

Real-time Sonography in Detecting Inadvertent Esophageal Intubation Among Difficult Intubation Patients

SDEIDI
Start date: September 20, 2021
Phase: N/A
Study type: Interventional

Early detection of esophageal intubation, one of the most common complications while performing endotracheal intubation (ETI), is crucial to adequate airway management, especially among patients suspected of difficult intubation (DI). Detective approaches with ventilation require time, increase the risk of emesis and aspiration to patients, and increase the risk of particle aerosolization to health providers under the epidemic of aerosol-borne diseases. Our study will determine the effectiveness of real-time sonography assisted to direct visualization to detect esophageal intubation before ventilation among DI patients.

NCT ID: NCT04833530 Not yet recruiting - Ultrasonography Clinical Trials

The Effect of Preoperative Anxiety, on Gastric Antrum Size in Women Undergoing in Vitro Fertilization

Start date: April 1, 2021
Phase:
Study type: Observational

Pulmonary aspiration is one of the most serious risks of general anesthesia and has been reported to occur in as many as 1 in 4000 cases of general anesthesia. Gastric ultrasound is an emerging point-of-care tool that provides bedside information on gastric content and volume. There have been a few factors which are thought to increase gastric size. Delayed gastric emptying such as caused by gastroparesis in Diabetes Mellitus is an example. Certain surgeries also cause gastroparesis. Other preoperative factors including pain, preoperative anxiety, and blood levels of estradiol or progesterone are less well studied.

NCT ID: NCT04825444 Not yet recruiting - Ultrasonography Clinical Trials

Clinical Study of Vascular Imaging Evaluation of Computed Tomography Photoacoustic Breast Imaging System

Start date: March 31, 2021
Phase:
Study type: Observational

Using color Doppler ultrasound to screen people with breast masses. For the patients who show only a single mass on either side of the breast in color Doppler ultrasound, computer tomography photoacoustic breast imaging will be performed. By comparing the two modalities, the blood vessel imaging performance of the computer tomography photoacoustic breast imaging system developed by Union Photoacoustic technologies Co., Ltd is evaluated. The evaluation index of this experiment is the percentage of blood vessel pixels in the same region of interest (Region Of Interest, ROI) to the total area of the ROI.
