Filter by:Ultrasound (US) is a more cost-effective, accessible, and available imaging technique to assess anterior talofibular ligament (ATFL) injuries compared with magnetic resonance imaging (MRI). However, challenges in using this technique and increasing demand on qualified musculoskeletal (MSK) radiologists delay the diagnosis. The investigators have already developed a deep convolutional network (DCNN) model that automates detailed classification of ATFL injuries. The investigators hope to use the DCNN in real-world clinical setting to test its diagnostic accuracy.
During pregnancy, certain conditions may arise that mean regular monitoring of both mother and baby are needed to ensure timely interventions and avoid the need for further treatments. These situations include problems with high blood pressure, obstetric cholestasis (characterised by liver-related itchiness), preterm premature rupture of membranes (PPROM), and a history of stillbirth. Monitoring typically involves assessing the mother's blood pressure and urine, recording the baby's heart rate over a specific duration, and conducting regular ultrasound scans. Such monitoring can require frequent hospital visits, often multiple times a week, which can be very time consuming. More recently, new technology has emerged, enabling remote monitoring of mother and baby outside of the hospital setting, such as their own home. However, research on these technologies is still very limited. Our study aims to address this research gap by inviting women with the above conditions to volunteer for home-based monitoring, alongside their routine hospital care. Participants will be divided into three groups: one group will use transducers, attached to the mothers tummy, to capture the baby's heartbeat; another group will use a handheld ultrasound device connected to their mobile phones, allowing them to observe the baby; and a third group will use both devices. All device information will be transmitted securely to the healthcare professional for analysis. The investigators aim to assess the feasibility of conducting remote monitoring of mother and baby, whilst understanding how acceptable the technology is received. Importantly, the data collected will only be evaluated by the research team and will not be intended to influence patient's current planned antenatal care. Women will receive comprehensive training on the devices. The study will additionally gather feedback from participating women through questionnaires, both at the study's outset and its conclusion, regarding their experiences and emotions related to the research.
The goal of this observational study is to quantitatively assess the renal microcirculation changes by contrast-enhanced ultrasound (CEUS) and to obtain systemic hemodynamic information by ultrasound Doppler at the same time, to analyze the relationship between renal microcirculation changes and systemic hemodynamic changes, and to explore the diagnostic value of CEUS in critically ill acute kidney injury.
The goal of this study is to quantitatively assess renal microcirculation changes by contrast-enhanced ultrasound and to obtain systemic hemodynamic information by ultrasound Doppler at the same time, to analyze the relationship between renal microcirculation changes and systemic hemodynamic changes, and to explore its predictive value in renal function recovery in patients with critical acute kidney injury. The main questions it aims to answer are: 1. To explore the quantitative parameters of contrast-enhanced ultrasound which can reflect the changes of renal microcirculation. 2. To explore the relationship between renal microcirculation and systemic hemodynamics. 3. To explore the value of renal microflow changes quantitatively evaluated by contrast-enhanced ultrasound in predicting renal function recovery.
Postextubation distress is detrimental to the prognosis of critically ill patients with successful spontaneous breathing trial. Failure to wean is known to be connected with heart, lung, and diaphragm problems. The aim of this study was to investigate how a composite model comprising diaphragm, lung, and heart ultrasonography indications could predict the weaning outcome. Methods: Ultrasonic features of the diaphragm, heart, and lungs are going to be collected along with clinical data about the patients. Either the successful weaning group or the failed weaning group is going to comprised the patients. Multivariate logistic regression analysis is going to be used to identify the variables that may be associated with the likelihood of weaning failure. A multiindicator combination model is going to be developed to increase the predictive accuracy after the possible indicators' accuracy in foretelling the weaning outcome was assessed.
Spinal anesthesia is frequently administered using the conventional landmark technique. Ultrasound is a non-invasive and safe approach. Neuroaxial anesthesia procedures can be conducted using two different ultrasound techniques; Real-Time Ultrasound Guided (USRTG) and Ultrasound-Assisted (USAS). The primary objective of this study is to compare the successes of spinal anesthesia applications using USRTG, USAS, and conventional landmark techniques on the first attempt in obese patients undergoing orthopedic surgery.
The goal of this clinical trial is to prospectively evaluate the potential benefits of injections with Augmented Reality enhanced Ulrasound versus standard Ultrasound or fluoroscopy participants where assigend for fluoroscopic joint injections oder for Ultrasound guided injection. The main question[s] it aims to answer are: - The primary objective is to evaluate the duration of the different interventions - the count of needle passes - assess the reduction of radiation exposure using AR US rather than fluoroscopic guidance for joint injections
The aim of the study is to determine the state anxiety levels of the pregnant women who were given and not given information about the fetus with USG images during the detailed ultrasound (USG) and to compare them in both groups. This research is in the design of pre-test-post-test applied and randomized controlled research. Dependent variables: State anxiety levels Independent variables: Being informed during ultrasound Control variables: Socio-demographic variables and obstetric variables.
This will be a prospective observational study where the investigator will scan patients' necks with an ultrasound and look for anatomical landmarks that may help identify the phrenic nerve.
The aim of this study is to assess the prevalence and precise grading of US abnormalities of the hand and wrist in asymptomatic patients with SLE, while comparing these findings with a group of patients with SLE with musculoskeletal signs or symptoms and with healthy controls.
