Filter by:This study aims to compare subjective image quality and diagnostic accuracy of a photon counting detector computed tomography (PCD-CT) scanner compared with an energy integrating detector (EID)-CT scanner as the reference standard.
The investigators will revise the Checklist for AI in Medical Imaging (CLAIM) guideline using Delphi consensus methods. An international panel of physicians, researchers, and journal editors with expertise in AI in medical imaging -- including radiology, pathology, dermatology, GI endoscopy, and ophthalmology -- will complete up to 3 web-based surveys. Participants who complete all survey rounds will be credited as contributors on resulting publications.
The goal of this pilot randomized controlled trial is to compare the effects of aquatic therapy versus standard care on paraspinal and gluteal morphology and function in individuals with chronic low back pain.The main questions it aims to answer are: 1. What are the effects of aquatic therapy versus standard care on a) paraspinal and gluteal muscle size, composition (e.g., fatty infiltration) and b) lumbar and gluteal muscle strength in individuals with chronic LBP? 2. Is aquatic therapy more effective than standard care to improve pain, function and psychological factors (e.g., kinesiophobia, catastrophizing, anxiety, and depression)? 3. Is using a digital application "play the pain" feasible to monitor pain levels and the activities that participants used to cope with pain? Participants will be assigned to either the aquatic therapy group or standard care group where they will undergo a 10-week intervention including two 60-minute session per week.
The aim of the proposed study is to define independent parameters for the diagnostic assessment of the perfusion situation of the calf muscle based on 3D-reconstruction of multispectral optoacoustic tomography (MSOT) in a cross-sectional collective of patients with PAD in Fontaine stage II and a healthy control group.
The study consists of collecting measurement data of the rachis in pregnant women and the subsequent outcome of her delivery. This will make it possible to validate a non-invasive imaging technique through software that can be used to study this anatomical curve proposing a new measurement method for the angle of lordosis. Finally, with the research data, the investigators will try to find a correlation between these variables (angle of lordosis and delivery outcome.
Currently, Sonazoid is mainly used for imaging liver lesions by assessing perfusion characteristics. However, the ultrasound technology is the same as for cardiac imaging and the stability of the microbubbles will potentially aid the detection of myocardial perfusion defects. This study will look at the feasibility of using sonozoid in this way.
Tuberculosis (TB) is one of the top ten causes of death worldwide with approximately 10 million cases globally and 1.2 million deaths. Sub-Saharan Africa carries the highest burden of TB. South Africa has one of the highest HIV and TB rates worldwide with an HIV prevalence rate in adults of 19% and a TB case notification rate of 615/100,000 in 2019. Over many years, focus has been paid to pulmonary TB and extrapulmonary TB (EPTB) has received only little attention even though it accounts for almost a quatre of all TB cases. The diagnosis of EPTB remains challenging simply because sample collection requires invasive procedures in the absence of a blood-based diagnostic test. Spinal TB (spondylitis or spondylodiscitis caused by Mycobacterium tuberculosis) - often known as Pott's disease - accounts for up to 10% of EPTB and affects young children, people with HIV-coinfection and elderly, and often leads to lifelong debilitating disease due to devastating deformation of the spine and compression of neural structures. Little is known with regards to the extent of disease and isolated TB spine as well as a disseminated form of TB spine have been described. The latter presents with a spinal manifestation plus disseminations to other organs such as the lungs, pleura, lymph nodes, the GIT or urinary tract or even the brain. In the Spinal TB X cohort, the investigators aim to describe the clinical phenotype of spinal TB using whole body PET/CT and identify a specific gene expression profile for the different stages of dissemination and compare findings to previously described signatures for latent and active pulmonary TB. A blood-based test for spinal TB would lead to earlier diagnosis and treatment in all settings globally and improve treatment outcome of this devastating disease.
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.
This prospective multicenter study will evaluate the efficacy of a real-time artificial intelligence system for detecting multiple ocular fundus lesions by ultra-widefield fundus imaging in real-world settings.
Patients with cancer and their caregivers may have difficulty understanding the site and extent of their disease. Poor comprehension may negatively impact patients and caregivers, leading to increased anxiety, reduced compliance, decreased trust of the physician, and limited shared medical decision making ability. Most patients want to be thoroughly informed, with over a third of cancer patients wishing they had been better informed about side effects that they experienced due to their treatment. The purpose of this study is to evaluate the impact of diagnostic imaging review using 3D virtual reality compared to standard 2D imaging review for patients and their caregiver(s) using a mixed methods approach of survey and qualitative interview based approaches.
