BACKGROUND AND PURPOSE Debate in the neuroradiology community surrounds the amount of formal training in sonography of the carotid arteries that should be provided to fellows. This study was designed to assess current practice patterns at both academic and nonacademic practices regarding the performance of carotid sonography. METHODS A neurovascular radiology survey was sent to all 102 progra...

BACKGROUND AND PURPOSE Sonographic brain studies are classically performed through the anterior fontanelle, but visualization of posterior supratentorial and infratentorial structures is poor with this approach. Posterior fontanelle sonography is recommended for better assessment of these structures. Our purpose was 1) to determine whether sonography of the brain through the posterior fontanell...

Intra-arterial Doppler sonography may complement arteriography by providing immediate physiological evidence of hemodynamic adequacy and by obviating unnecessary angioplastic dilation. We used a Doppler-tipped guidewire in 16 patients and obtained velocity measurements at the site of stenosis immediately before and after carotid artery stenting (CAS) in 10 patients. Intra-arterial Doppler sonog...

Urethral calculi Sonography Noninvasive screening technique Abstract We performed sonography in 7 males with membranous and posterior urethral calculi. Sonography demonstrated the urethral calculi in all 7 patients. These findings suggest that sonography is useful as a noninvasive screening technique for urethral calculi.

We prospectively evaluated the diagnostic value of sonography and magnetic resonance imaging (MRI) in 24 shoulders in 23 patients with suspected rotator cuff tears using arthrography as gold standard. Sonography demonstrated 14 of 15, MRI 10 of 15 rotator cuff tears, respectively. Sonography diagnosed seven of nine intact rotator cuffs correctly, MRI eight of nine. In a retrospective study we r...

OBJECTIVE The purpose of this study was to evaluate the ability of sonography to depict and guide biopsies of mammographically suspicious microcalcifications and to reveal the mammographic features and histologic outcomes of lesions amenable to sonographically guided biopsy. SUBJECTS AND METHODS . Suspicious clusters of microcalcifications without other mammographic abnormalities were evaluat...

The aim of this work was to show contribution of power Doppler imaging in the diagnosis of the carotid body tumors. Six patients with a nontender mass beneath the mandibular angle were evaluated with gray scale and power Doppler sonography. Well-defined, solid, weakly hyperechoic masses were noted on gray scale sonography in the carotid bifurcation. Power Doppler sonography showed abundant flow...

introduction: pulmonary hyperinflation in patients with chronic obstructive pulmonary disease (copd) can increase the breathing rate and reduce diaphragmatic movements by pushing the diaphragms downward and limiting their movements; this, in fact, can affect the breathing process. the purpose of this study was to compare diaphragmatic movements in copd patients and healthy ones and to evaluate ...

conclusions in the first one hour, diclofenac suppository is able to control the fever more efficient than paracetamol suppositories. results the average rectal temperature in the paracetamol group was 39.6 ± 1.13°c, and 39.82 ± 1.07°c in the diclofenac group (p = 0.37). the average rectal temperature, one hour after the intervention, in the paracetamol and the diclofenac group was 38.39 ± 0.89...
