urinary tract infections are common in children. the available gold standard method for diagnosis, tc-99m dimercaptosuccinic acid scan is expensive and exposes patients to considerable amount of radiation. this study was performed to compare and assess the efficacy of power doppler ultrasound versus tc-99m dmsa scan for diagnosis of acute pyelonephritis. a quasi experimental study was conducted...

OBJECTIVE To determine if colour Doppler ultrasonography can characterise the nature of intraarticular echogenic structures and synovial villi more precisely than conventional ultrasonography. METHODS This is a prospective study on 20 patients--10 with rheumatoid arthritis and 10 with osteoarthritis. Colour Doppler ultrasonography of the knee joints was performed prior to total prosthetic rep...

OBJECTIVES Our purpose was to investigate cervical lymphadenopathies by using color Doppler spectral analysis and power Doppler ultrasonography methods as well as B-mode ultrasound and to classify them as malignant or benign lesions and to compare the results with the histopathological findings. PATIENTS AND METHODS Sixty-nine lymph nodes of 69 patients were evaluated with color and power Dop...

A 40-year-old woman with a 3 cm sigmoid polyp lesion who underwent a laparoscopic colon resection after intraoperative localisation of the lesion using laparoscopic ultrasonography coupled with colour power Doppler is described. She has successful intraoperative detection of the polyp followed by radical laparoscopic removal of the lesion. The advantage of using laparoscopic high resolution ult...

INTRODUCTION We report the first case of the successful detection of postpartum unruptured vaginal pseudoaneurysm using power- and pulsed-Doppler ultrasonography after delivery. CASE DESCRIPTION A 38-year-old primiparous Japanese woman had a vaginal laceration with pulsatile bleeding after delivering by vacuum extraction. Transvaginal ultrasonography of the repaired vaginal wall showed an 18 ...

OBJECTIVE To determine the diagnostic accuracy of power Doppler and grey scale ultrasonography, assess the relationship between severity measures and neovascularity, and describe the intra-tendon distribution of neovascularity in chronic tennis elbow. DESIGN Between group cross sectional study. SETTING Sports medicine clinic and radiology centre. PARTICIPANTS 32 affected elbows (median an...

background: this study aimed to compare the percentage of detection of periarthritis in patients with rheumatoid arthritis using clinical examination and ultrasound methods. materials and methods: this study is a cross?sectional study which was conducted in al?zahra hospital (isfahan, iran) during 2014–2015. in our study, ninety patients were selected based on the american college of rheumatolo...

Three-dimensional color Doppler ultrasonography is a new technique to evaluate the pattern of blood vessels. This study was performed to assess the feasibility of this method in evaluation of kidney vasculature pattern in dogs. In this paper, visualization of the Renal, Interlobar, Arcuate, and interlobular arteries and veins using 3D color Doppler ultrasonography in dogs is shown and the techn...
