Objective. To determine the frequency of the various ultrasound findings in hand joints in patients with psoriatic arthritis and correlate grayscale and Power Doppler ultrasonography findings with Disease Activity Score 28. Methods. This prospective study was performed in 30 patients. Ultrasound evaluation of 28 joints of both hands was undertaken and various findings were recorded including sy...
OBJECTIVE Logistic regression analysis (LRA), Support Vector Machine (SVM) and a neural network (NN) are commonly used statistical models in computer-aided diagnostic (CAD) systems for breast ultrasonography (US). The aim of this study was to clarify the diagnostic ability of the use of these statistical models for future applications of CAD systems, such as three-dimensional (3D) power Doppler...
OBJECTIVE To assess the interobserver reliability of the main periarticular and intra-articular ultrasonographic pathologies and to establish the principal disagreements on scanning technique and diagnostic criteria between a group of experts in musculoskeletal ultrasonography. METHODS The shoulder, wrist/hand, ankle/foot, or knee of 24 patients with rheumatic diseases were evaluated by 23 mu...
25 Although color Doppler ultrasonography has been used to evaluate testicular blood flow in 26 many species, very little has been done in goat. Eight male Shiba goats were exposed to a 27 single intramuscular injection of either gonadotropin-releasing hormone (GnRH group; 28 1μg/kg BW) or human chorionic gonadotropin (hCG group; 25 IU/kg BW). Plasma 29 testosterone (T), estradiol (E2), and inh...
BACKGROUND Sentinel lymph node (SLN) biopsy is the standard of care for breast cancer patients with non-palpable axillary lymph nodes. We evaluated the usefulness of contrast-enhanced ultrasonography in preoperative detection of malignant SLNs. METHODS 50 patients with breast cancer (median age: 60 years) underwent a color power Doppler ultrasonography with intravenous contrast (Sonovue®) pre...
OBJECTIVE To assess the value of quantitative vascular imaging by power Doppler US (PDUS) as a tool that can be used to stratify patient risk of joint damage in early seropositive RA while still biologic naive but on synthetic DMARD treatment. METHODS Eighty-five patients with seropositive RA of <3 years duration had clinical, laboratory and imaging assessments at 0 and 12 months. Imaging ass...
Transcranial Doppler ultrasonography has been used to detect microemboli in the middle cerebral artery during orthopedic surgery. We conducted a comprehensive systematic literature review of transcranial Doppler ultrasonography in orthopedic surgery to evaluate its status in this setting. Fourteen studies were selected for qualitative analysis. The highest number of patients studied was 45; emb...
OBJECTIVES To analyze the nasal superficial arterial vasculature and to compare these anatomic findings with the results of ultrasonography Doppler investigations to evaluate nasal blood flow in physiological and pathologic conditions. METHODS We performed 40 ultrasonography Doppler investigations in patient volunteers, 20 facial anatomic dissections in fresh cadavers, and a review of the lit...
