Introduction: This study aims to provide a comparative evaluation of the clinical and paraclinical diagnosis in patients with acute appendicitis. Methods: After investigation, the cases of 200 patients with symptoms of acute appendicitis who had referred to Shahid Beheshti Hospital of Yasuj-Iran in 2018 year and underwent surgery were examined. Variables of age and sex, pathology results, ultr...

INTRODUCTION We studied the diagnostic accuracy of bedside lung ultrasound (the presence of a comet-tail sign), N-terminal pro-brain natriuretic peptide (NT-proBNP) and clinical assessment (according to the modified Boston criteria) in differentiating heart failure (HF)-related acute dyspnea from pulmonary (chronic obstructive pulmonary disease (COPD)/asthma)-related acute dyspnea in the prehos...

A teleoperation approach to diagnostic ultrasound, in which the ultrasound transducer is positioned by a robot, is described in this paper. An inherently safe counterbalanced robot has been designed and tested in carotid artery examinations. The feasibility of using visual servoing for motion in the plane of the ultrasound probe has also been demonstrated using a modified image correlation algo...

background: developmental dysplasia of hip (ddh) is a common childhood disorder, and ultrasonography examination is routinely used for screening purposes. in this study, we aimed to evaluate a modified combined static and dynamic   ultrasound technique for the detection of ddh and to compare with the results of static and dynamic ultrasound techniques.       methods: in this cross-sectional stu...

Increasing prevalence of chronic liver disease has led to dramatically increased demands on ultrasound for diagnosis, monitoring and surveillance of complications. Targeted ultrasound of the liver provides an efficient and possibly more accurate means of meeting this demand. It uses a matrix to guide the ultrasound examination to address the specific clinical questions commonly asked in this po...

abstract: in this study, response surface methodology was used to optimize ultrasound osmotic pretreatment with finished freeze drying of black cherries. freeze drying is a separation process based on the  sublimation phenomenon. this process has the following advantages as compared to the conventional drying process, maintenance of the structure, moisture removal at low temperature (reduced tr...

Using ultrasound technique, this study revealed certain previously undocumented tongue behaviours of Mandarin vowels /a/, /i/ and /u/. The results were achieved by using a modified SS ANOVA method that was capable of analyzing and comparing simultaneously three or more objects (e.g., vowels) in ultrasound imaging. Also developed and used was a correction method to compensate for jaw rotation.

BACKGROUND Blockade of the saphenous nerve is often used for surgeries below the knee. Depending on the approach, success rates vary widely ranging from 33% to 88%. In this prospective volunteer study, we compared 2 ultrasound-guided techniques, the modified vastus medialis and perifemoral saphenous nerve block with a below the knee field block. METHODS Twenty volunteer adults, in a single-bl...

The value of interventional ultrasound in the diagnosis and treatment of submucous myoma of the uterus was assessed to study the ultrasonographic features of modified sonohysterography for submucous polyp of uterus. A total of 25 patients diagnosed preliminarily as submucous myoma of the uterus via conventional ultrasound examination from June 2014 to December 2016 were enrolled in the study. T...

INTRODUCTION Duplex ultrasound facilitates bedside diagnosis and hence timely patient care. Its uptake has been hampered by training and accreditation issues. We have developed an assessment tool for Duplex arterial stenosis measurement for both simulator and patient based training. METHODS A novel assessment tool: duplex ultrasound assessment of technical skills was developed. A modified dup...
