BACKGROUND In veterinary medicine, contrast-enhanced ultrasonography allowed the accurate quantification of liver, splenic and kidney vascularization in healthy dogs and the differentiation between malignant and benign hepatic, renal, and splenic nodules in dogs and cats based on perfusion patterns. The utility of contrast-enhanced ultrasonography in other applications is still under study. The...

Objectives This study was done to evaluate the normal fetal cerebral lateral ventricle dimensions with transabdominal ultrasonography. The atrial width (AW), ventricle-to-choroid measurement (V-C), ventricle-to-hemisphere ratio (VHR), and combined anterior horn measurement (CAHM) were taken. Methods This was a cross-sectional study involving 400 normal singleton pregnant subjects whose gestatio...

To compare and determine color Doppler ultrasonography (CDU) parameters that is the most reliable parameter for predicting thyroid functional status between euthyroid and hyperthyroid states. We retrospectively reviewed data from a total of 256 patients (197 females and 59 males) who had undergone CDU from December 2003 to April 2008. Patients’ age ranged from 11-81 yr with average of 38.6 yr. ...

conclusions: in this study, kidney transplant recipients with a lower ri and pi and a higher edv at 1week showed better graft function at 6 months after transplantation. results: fourteen patients (15.4%) had impaired graft function after 6 months (gfr less than 60 ml/min/1.73m2). multivariate linear regression analysis showed significant correlation between gfr at 6 months and ri, pi and edv w...

Background and aims. Although salivary gland tumors are not very common, early diagnosis and treatment is crucial because of their proximity to vital organs, and therefore, determining the efficacy of new imaging procedures becomes important. This study aimed to evaluate the efficacy of magnetic resonance imaging (MRI) and color doppler ultrasonography parameters in the diagnosis and differenti...

OBJECTIVE To verify the feasibility of initial parameters of ultrasonography or electromyography for the prediction of effect after steroid injection therapy in a carpal tunnel syndrome (CTS) patient. METHOD We recruited individuals with clinical and electrodiagnostic evidence of CTS. Results from the Boston self-assessment questionnaire, median motor and sensory nerve conduction studies, and...
