We describe the use of a recently developed technique in the field of color Doppler sonography, called power Doppler or color Doppler energy, that produces better images of the intracranial arteries than those obtained by conventional color Doppler techniques. Color Doppler energy makes it possible to identify aneurysms and their relationship to the parent artery, thus allowing one to observe h...

OBJECTIVE The purpose of this study was to prospectively investigate the role of high-resolution and color Doppler sonography in the differential diagnosis of acute scrotum and testicular torsion in particular. METHODS Patients who underwent sonography for acute scrotum between April 2000 and September 2005 were included in the study. Gray scale and color Doppler sonography of the scrotum was...

Introduction: Thyroid nodules are frequent occurrences, and whenever diagnosed, it is necessary to rule out of malignancy. Valuable diagnostic methods in this field are sonography and fine needle aspiration. In this study while investigating these two methods, we compared them with postsurgical pathologic findings. Materials and methods: This is a cross sectional, descriptive-analytical study. ...

AIM To investigate the potential usefulness of contrast-enhanced three-dimensional (3D) power Doppler sonography in the differentiation of benign and malignant adnexal lesions. METHODS Thirty one patients with complex adnexal lesions of uncertain malignancy at transvaginal B-mode and/or color Doppler sonography were prospectively evaluated with three-dimensional power Doppler sonography befor...

BACKGROUND AND PURPOSE Optimal estimation of cerebral blood-flow volume (BFV) may be an important indicator for better evaluation of the patients with cerebrovascular disorders. In this study, we compared the BFV values at bilateral internal carotid and vertebral arteries of healthy volunteers obtained with color Doppler, power Doppler, and B-flow ultrasound (US) studies and tried to determine ...

conclusion gray scale sonography in combination with doppler sonography could be a trustworthy technique in differentiating metastatic lymph nodes from reactive ones. although, circulation pattern had a higher diagnostic accuracy in the present study, combination of sonographic characteristics could be more beneficial in differentiating metastatic cervical nodes from reactive ones. results the ...

PURPOSE To describe a case where detection of blood flow in the central retinal artery and the central retinal vein was limited by an artifact evoked by the optic disc drusen. METHODS Case report. RESULTS During color Doppler sonography, examination of optic disc drusen may generate an artifact--the so-called twinkling artifact--which can simulate blood flow and make evaluation of the central...

Carotid body tumors typically arise at the level of the common carotid bifurcation where the carotid body exists. Superior and inferior extension beyond the carotid body may occur as well, especially if the tumor is long-standing. We herein describe a case of carotid body tumor in a patient who presented with a right-sided neck mass for 30 years. Computed tomography angiography (CTA) and B-mode...

A rare case of posttraumatic high-flow priapism is presented. A 20-year-old man underwent diagnostic procedure with color Doppler sonography and angiography. On color Doppler sonography and selective and supraselective angiographic images, arteriocavernosal fistula and pseudoaneurysm were detected in the proximal part of the right cavernous body. Complete detumescence of the penis was achieved ...
