OBJECTIVES To evaluate the diagnostic efficiency of two-dimensional (2D) and three-dimensional (3D) transvaginal ultrasonography, power Doppler angiography (PDA) and gel infusion sonography (GIS) at offline analysis for recognition of malignant endometrium compared with real-time evaluation during scanning, and to determine optimal image parameters at 3D analysis. METHODS One hundred and sixt...

Background. There are a variety of techniques for targeting placement of an infraclavicular blockade; these include eliciting paresthesias, nerve stimulation, and 2-dimensional (2D) ultrasound (US) guidance. Current 2D US allows direct visualization of a "flat" image of the advancing needle and neurovascular structures but without the ability to extensively analyze multidimensional data and all...

A 30-year-old asymptomatic man with chronic hepatitis B was evaluated for an incidentally visualized intracardiac mass on abdominal ultrasonography. Two-dimensional (2D) transthoracic echocardiography (TTE) revealed a structurally normal heart except for the presence of homogeneously echodense, round, mobile mass (2.0×2.8 cm) within the left ventricular cavity (Fig. 1a, Video 1a). No flow abnor...

Bilateral pulmonary sequestration (PS) is a very rare congenital malformation. We describe a case of bilateral intralobar pulmonary sequestration (ILS) in a newborn. Both sequestrations received arterial supply from separate branches of the descending aorta and venous drainage was into ipsilateral inferior pulmonary veins. Prenatal ultrasonography showed cystic changes in the lungs. Computed to...

COMPARATIVE STUDY OF HYSTEROSCOPY AND 3D ULTRASOUND FOR DIAGNOSING UTERINE CAVITY ABNORMALITIES (Abstract) Objective: Hysteroscopy is the most accurate method for diagnosing intrauterine pathologies related to abnormal blee ding and infertility. The accuracy of three-dimensional (3D) ultrasonography and hysteroscopy were compared in identifying uterine cavity abnormalities. Material and methods...

To compare the fetal cerebellum and cisterna magna length measurements by means of two- (2DUS) and three-dimensional (3DUS) ultrasonography using the three-dimensional extended imaging (3D XI), a cross-sectional study with 69 healthy pregnant women between 18 and 24 weeks was performed. For the measurements by 2DUS, the axial planes were used and for the 3DUS a sequence of adjacent axial slices...

Background: As gestational age grows, the risk of newborn respiratory distress syndrome (RDS) diminishes because lungs are last foetal organs to properly mature. While neonatal RDS does not just occur following preterm births, it is often thought as a disorder premature babies. This study sought determine how prenatal lung capacity and Pulmonary artery resistance index (PARI) affected probabili...
