BACKGROUND AND PURPOSE Nonimaging transcranial Doppler sonography (TCD) and imaging TCD (TCDI) are used for determination of the risk of stroke in children with sickle cell disease (SCD). The purpose was to compare angle-corrected, uncorrected TCDI, and TCD blood flow velocities in children with SCD. MATERIALS AND METHODS A total of 37 children (mean age, 7.8 +/- 3.0 years) without intracrani...

Splenic arteriovenous fistulas (AVFs) are rare lesions. Herein, we report a 40-year-old man with portal hypertension secondary to splenic AVF, which was primarily diagnosed by color Duplex sonography. Sonography revealed a non-pulsatile, cyst-like mass at the splenic hilum with an unusual comma-shaped extension. In color duplex sonography, complete color fill-in of the lesion with the character...

Conventional sonography provides twodimensional (2D) views of three-dimensional (3D) structures that an experienced ultrasonographer has to dynamically examine in order to create their own 3D impression of the object of interest. In contrast, 3D sonography allows the simultaneous assessment of individual sectional planes, which dependent upon the particular field of interest may be examined in ...

This study is to prospectively evaluate the efficiency of sonography for volvulus diagnosis in neonates with clinically suspected intestinal malrotation.A total of 83 patients with suspected intestinal malrotation who underwent detailed abdominal sonography and upper gastrointestinal contrast study were included. Malrotation was characterized by inversion of the superior mesenteric artery (SMA)...

OBJECTIVE To describe the cases of 2 fetuses with aneurysms of the vein of Galen diagnosed prenatally. METHODS The techniques used were conventional sonography, three-dimensional sonography, and ultrafast magnetic resonance imaging. On the basis of these imaging modalities, prognostic factors, such as drainage and secondary damage, were assessed. RESULTS The first fetus had good prognostic ...

Portal vein aneurysm is a relatively uncommon entity. It is often an incidental, asymptomatic nding. With the increasing availability of advanced imaging modalities like Doppler ultrasound, computed tomography and magnetic resonance imaging, portal venous system aneurysms are being increasingly reported. We report two cases of intra hepatic portal vein aneurysm diagnosed incidentally on ultra-...

The selection of patients with severe vertebrobasilar artery stenosis for angioplasty is based mainly on clinical experience rather than on controlled data. We present a patient with severe vertebral artery stenosis in whom we could document the positive effect of angioplasty on posterior circulation hemodynamics by using transcranial Doppler sonography.

Background. Conventional sonography is the primary imaging tool for these pregnant women who present with an ovarian teratoma. In some cases, however, sonography diagnosis is difficult. We report a case of ovarian teratoma during pregnancy diagnosed by three-dimensional Power Doppler. The cyst was removed via laparotomy without fetal or maternal complications. Three-dimensional ultrasound with ...
