OBJECTIVE Cavernous transformation of the portal vein is defined as the formation of venous channels within or around a previously thrombosed portal vein. The purpose of this work was to study the hemodynamic consequences of cavernous transformation of the portal vein in a group of afflicted patients by use of Doppler sonography. We wished to study the(More)
PURPOSE To evaluate clinical response to treatment of calcified tendinitis of the shoulder by using a modified percutaneous ultrasonography (US)-guided fine-needle technique. MATERIALS AND METHODS Thirty shoulders of 30 consecutive patients (23 women, seven men; mean age, 47.4 years) with chronic shoulder pain (average duration, 43.1 months) refractory to(More)
PURPOSE To evaluate the sonographic findings of plantar fasciitis. MATERIALS AND METHODS Both feet of 15 patients who had a clinical diagnosis of plantar fasciitis were evaluated with ultrasound (US) by using a 7.0-MHz linear-array transducer. Heel pain was unilateral in 11 patients and bilateral in four. Sagittal sonograms were obtained, and the(More)
OBJECTIVE The objective of this article is to describe a simplified fluoroscopically guided technique of shoulder joint injection that uses the rotator cuff interval. CONCLUSION Shoulder arthrography using an anterior approach through the rotator cuff interval is an effective, rapid, and easy-to-perform injection technique. In most patients, this(More)
OBJECTIVE The aim of the study was to determine the sonographic findings of snapping hip and to correlate the findings with the presence or absence of pain. MATERIALS AND METHODS Twenty patients with snapping hip were examined with sonography. Conventional and dynamic sonographic examinations of both hips were performed using a 5.0- or 7.0-MHz transducer.(More)
PURPOSE To report the magnetic resonance (MR) imaging findings in seven patients with posterior ankle impingement (PAI) syndrome. MATERIALS AND METHODS Seven patients-three ballet dancers, one badminton player, one soccer player, one hockey player, and one construction worker-who presented with posterior ankle pain were assessed with MR imaging. Their(More)
Ultrasound is able to play a key role in the management of musculoskeletal soft tissue infections. It is an easily accessible imaging modality that can be used immediately after plain radiographs have been obtained. Quick diagnosis is essential in the clinical setting of musculoskeletal infection because delay can lead to significant morbidity. In addition(More)
The purpose of this study was to determine the prevalence and localization of focal areas of sparing in a population of patients with fatty infiltration (steatosis) of the liver. We also sought to determine if the blood supply of the gallbladder has an effect on fatty infiltration of the liver adjacent to it. We studied 290 patients with sonographic signs(More)
The purposes of this study were to look for the inferior mesenteric artery in patients undergoing abdominal sonography, to determine in what percentage of patients it is visible, and to characterize Doppler flow patterns of the inferior mesenteric artery in fasting patients without intestinal vascular disease. The inferior mesenteric artery was sought in(More)
In an open, clinical trial comprising a total of 49 depressed in-patients, a new selective 5-HT uptake inhibitor citalopram was administered by intravenous infusion in doses of 20-60 mg once daily for per 3 weeks. The therapeutic effect was assessed globally and by means of the CPRS subscale for depression (MADRS). About 40 per cent of the patients showed a(More)
