Background: Lung ultrasound is frequently used to identify pulmonary oedema, using the 'B line' artefact. A small study in 2011 suggested that novice sonologists had a potential diagnostic accuracy of 85%, when performing the test without reference to other patient information. Aim: We aimed to test the overall diagnostic accuracy of novice clinician sonologists incorporating the 2011 protocol ...

Introduction: Acute appendicitis is the most common cause of acute abdomen and is considered as a surgical emergency. Approximately, 10% of patients with acute appendicitis and delayed diagnosis can face many complications. This study was designed to examine the correlation between ultrasound and pathological findings in patients with appendicitis and aimed t...

BACKGROUND High-intensity focused ultrasound has been applied to internal organs from outside the body to ablate tissue. No published study has assessed the feasibility of ablating cardiac tissue within the beating heart by use of this type of therapeutic ultrasound. The purpose of this study was to determine whether high-intensity focused ultrasound can be used to ablate the atrioventricular (...

Current research suggests that incidence and heterogeneity of autism spectrum disorder (ASD) symptoms may arise through a variety of exogenous and/or endogenous factors. While subject to routine clinical practice and generally considered safe, there exists speculation, though no human data, that diagnostic ultrasound may also contribute to ASD severity, supported by experimental evidence that e...

background in stable patients with blunt abdominal trauma, accurate diagnosis of visceral injuries is crucial. objectives to determine whether repeating ultrasound exam will increase the sensitivity of focused abdominal sonography for trauma (fast) through revealing additional free intraperitoneal fluid in patients with blunt abdominal trauma. patients and methods we performed a prospective obs...

Clinical use of diagnostic ultrasound at point-of-care or emergency situations, although common, has not been well documented in veterinary medicine. Medical records of after-hour emergency equine admissions during a 10-year period were reviewed and horses that received ultrasound scans were identified. Data sheets for each ultrasound scan performed during emergency clinical evaluation were col...

OBJECTIVES To determine whether CA 125 measurement is superior to ultrasound imaging performed by an experienced examiner for discriminating between benign and malignant adnexal lesions, and to determine whether adding CA 125 to ultrasound examination improves diagnostic performance. METHODS This is a prospective multicenter study (International Ovarian Tumor Analysis (IOTA) study) conducted ...
