Background Pial arteriovenous fistula (AVF) is composed of one or more direct arterial feeding vessels with a single draining vein without nidus. A patient with the disease with high-flow AV shunting in the neonatal period not only suffers from high-output cardiac failure but also shows secondary neurological sequelae. In vein of Galen aneurysmal malformation, superior vena cava (SVC) flow meas...

Superior vena cava (SVC) syndrome is a group of clinical signs caused by the obstruction or compression of SVC and characterized by edema of the head, neck, and upper extremities, shortness of breath, and headaches. The syndrome may be caused by benign causes but most of the cases are caused by lung or mediastinal malignant tumors. Stenting of SVC has become widely accepted as the palliative tr...

Central venous thrombosis is an important complication of venous catheterization. We presented a 49-year-old male patient who developed massive central venous thrombosis causing superior vena cava (SVC) syndrome after placement of a right subclavian vein port catheter. The patient had inoperable gastric cancer for which he had been receiving chemotherapy for two years. He had a six-month histor...

Cytomegalovirus (CMV) is the most common cause of congenital infection worldwide. Urine viral culture is the standard for CMV diagnosis in neonates and infants. The objectives of this study were to compare the performance of serial paired rapid shell vial cultures (SVC) and routine viral cultures (RVC), and to determine the optimal number of cultures needed to detect positive cases. From 2001 t...

The Joint Video Team (JVT) of the ITU-T Video Coding Experts Group (VCEG) and the ISO/IEC Moving Picture Experts Group (MPEG) has standardized a scalable video coding (SVC) extension of the H.264/AVC standard. Thanks to SVC, it is possible to partially transmit or decode a video bitstream resulting in various video qualities (spatial, temporal or reduced delity). Within our lab, the aim is to d...

PATHOPHYSIOLOGY The superior vena cava (SVC) is a short large-diameter vein (about 7 cm long) that carries deoxygenated blood from the upper half of the body to the heart’s right atrium (Figure 1). The SVC is located in the anterior right superior mediastinum, surrounded by the sternum, ribs, vertebral bodies, and aorta (Nunnelee, 2007). When the SVC is compressed, blood flows through the colla...

In this paper, the performance of the emerging MPEG-4 SVC CODEC is evaluated. In the first part, a brief introduction on the subject of quality assessment and the development of the MPEG-4 SVC CODEC is given. After that, the used test methodologies are described in detail, followed by an explanation of the actual test scenarios. The main part of this work concentrates on the performance analysi...
