Filter by:The study contains the result from a comparison of diagnostic outcomes about lung collapse by using lung ultrasonography as a new diagnostic test compares to fiberoptic bronchoscopy as the standard test.
Contrast-enhanced ultrasound(CEUS) of carotid artery plaque is a novel method that enabled direct visualization of neovessels in the vulnerable plaque. Plaque enhancement with CEUS showed correlation with the histologic density of neovessels within the carotid plaque and the previous cardiovascular events. Vulnerable plaques with a high risk of thromboembolic complications and rapid progression is associated with acute ischemic stroke. The prognostic value of vulnerable carotid artery plaque depicted with CEUS has not been fully investigated. The purpose of this study is to define prognostic value of plaque enhancement on carotid CEUS in acute stroke patients. Research question is; in acute ischemic stroke patients with ipsilateral carotid plaque as probable etiology of stroke, is the presence of carotid plaque enhancement on CEUS independent predictor of future stroke.
To set up a Cooperative Network by enrolling 5000 patients with Adenomyosis(AM) from multiple centers.Based on the Network platform and Database,the investigators try to explore the diagnostic strategies for AM and carry out epidemiological survey on the semeiology of AM.In addiction，the investigators expect to conduct research on the effect and the follow-up fertility outcomes of different medical or surgical treatment, the etiology of AM and endometriosis,the perspective investigation of the malignant transformation of AM ;the high-risk factors of AM,and finally propel the formation of Expert Consensus and Clinical Guidelines about AM which suitable to chinese conditions.
Achilles tendon is a frequent lower-limb tissue where tendinopathy may arise. Percutaneous Therapeutic Electrolysis (EPTE®) is an electronic device that enables to treat accurately, guided by an ultrasound, the tendon injured area by applying a galvanic current through an acupuncture needle. Thus, the first stage of physiological regenerative process may be obtained. Design: Randomized Controlled Clinical Trial. Objectives: To know the effectiveness of Percutaneous Therapeutic Electrolysis (EPTE®) versus a sham intervention at improving pain and function in patients who undergo Achilles Chronic Tendinopathy and to determine the efficiency of Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle versus Percutaneous Therapeutic Electrolysis (EPTE®) with bipolar needle at improving pain and function in patients who undergo Achilles Chronic Tendinopathy. Participants: patients diagnosed with Achilles Chronic Tendinopathy. Setting. Infanta Leonor Hospital, Madrid, Spain. Experimental intervention: Percutaneous Therapeutic Electrolysis (EPTE®) with monopolar needle, 330 microamps, 1 min 20 sec versus bipolar needle. Sham intervention: the guide tube of the needle contacted with the skin and the device remained switched on to simulate its functioning.
The goal of this study is to assess the impact of perioperative point-of-care ultrasound (POCUS) assessment on patient-important outcomes (e.g. hospital length of stay, length of stay in recovery, mortality etc.) and perioperative patient management strategies, in patients undergoing non-elective non-cardiac surgeries.
We plan to compare single person short axis view with two person long axis view
The aim of this research study is to describe the impact of rheumatologist performed ultrasound on the diagnosis and management pathways of patients with rheumatoid arthritis. Primarily, to compare the time from first visit to treatment initiation between patients with and without rheumatologist-performed ultrasound assessment.
There is currently a lack of evidence to support the use of perioperative point-of-care ultrasound to assess the outcomes in high risk surgical patients. Thus, the purposes of this study were to evaluate whether perioperative use of point-of-care ultrasound can reduce the worse postoperative outcomes in high surgical patients.
Evaluate whether discrete landmarks of the proximal humerus can be identified using ultrasound in patients with various body habitus and BMI.
Fifteen healthy subjects under non-invasive ventilation will be have a recording of surface electromyogram, measurements of airway flows and pressures as well as a continuous ultrasound. The provocation of leaks on the Ventilation circuit and expiratory trigger modulation will generate a number of asynchronies between the subject and the respirator. These records will help to assess the agreement between the detection of asynchronies using electromyography of the respiratory muscles (technique of reference) and the diaphragmatic echography. We will also compare the respective performance of two techniques of diaphragmatic exploration (excursion and thickening of the diaphragm). A sensitivity of Ultrasound technique of at least 90% will be interpreted as a satisfactory index of concordance.
