Teleradiology networks transmit digital radiographic images from one location to another. These networks are wide area networks. Teleradiology networks are used for diagnostic purposes and preview tasks. Wide area networks for teleradiology use public service switching. The use of fiber optics networks provide reduced costs and increased flexibility. An example is presented that compares the cost of teleradiology networks.
In a patient with right-sided stomach and malrotation of the small bowel and cecum visualized by gastrointestinal x-ray studies using barium, a right-sided spleen was demonstrated by 99mTc-sulfur colloid and 51Cr-labeled red blood cell imaging. The sulfur colloid study also demonstrated that the liver was in its usual right upper quadrant location.
A characteristic liver scintigraphic finding was observed in a 2-month-old infant with hepatic herniation through a right-sided posterolateral congenital diaphragmatic defect (Bochdalek). The liver scintigrams showed an oblique band of decreased radioactivity dividing the liver into an inferior anteromedial portion and a superior posterolateral portion. In spite of the markedly abnormal liver scintigram, other diagnostic studies, including pneumoperitoneum abdominal radiography, remained negative. The liver scintigram can provide life-saving information in the diagnosis of congenital diaphragmatic hernia, as in the present case. The distinctive liver-scan findings among the various types of common diaphragmatic hernias are also briefly reviewed.
