Acoustic radiation force imaging (ARFI) is a type of quantitative sonoelastography (SE) that has been used to determine tissue stiffness in many disorders including liver fibrosis, breast cancer, thyroid nodules and more recently, cutaneous scleroderma. However the use of this technology for the assessment of skin lesions in the paediatric population has not yet been investigated. The purpose of this study is to test the feasibility of using ARFI SE to quantify the stiffness of morphea or localized scleroderma (LS) and hypertrophic burn scars (HTS), two skin conditions in which there is excessive deposition of collagenous and non-collagenous extracellular matrix causing fibrosis.

Despite being recognized as a secondary sign of appendicitis, no clear definition exists about the amount of intra-abdominal fluid considered physiologic in children. The purpose is (1) to assess the amount of intra-abdominal free fluid by US and MRI in children with suspected appendicitis, (2) to detect the performance characteristics of US for detecting free fluid, and (3) to determine the association between fluid volume and perforated appendicitis. An additional ex-vivo study was done to assess the validity of US measurement abdominal free fluid volume using phantoms. Read More

POC-US aims at shortening the scanning and interpretation time being easy to use by clinicians and allied health professionals at the time of patients’ physical examination. Our purposes are: 1. To compare POC-US to detailed US and MRI in evaluating hemophilic arthropathy. 2. To point out limitations of POC-US that can decrease its accuracy. 3. To propose strategies to refine protocols.

Optimization of ultrasound (US) scanning planes for evaluation of different joint components of subjects with blood-induced arthropathy can decrease scanning time without compromising diagnostic information. The purpose of this study was to identify the most diagnostically informative set of US planes for assessment of arthropathy in growing joints of persons with hemophilia based on frequency of findings.
