Early in the article, venography, venous pressure measurements, and, indeed, efforts to obtain a specific diagnosis by tissue biopsy are labeled as dangerous. The authors indicate that the various diagnostic procedures may lead to life-threatening complications such as respiratory obstruction, aspiration...
Isolated right superior vena cava draining into left atrium diagnosed by radionuclide angiocardiography. Skeletal scintigraphy employing a new technetium-labeled diphosphonate compound (99mTc-Sn-EHDP) was compared with fluorine-18 bone scanning and radiographic skeletal survey to determine its ability to de...
Superior vena cava obstruction by metastatic mediastinal testicular seminoma. Imaging of collateral pathways during gastrointestinal bleeding scintigraphy with 99m Tc labeled red blood cellsS100A12, a calcium-binding proinflammatory protein secreted by granulocytes, has been associated with different diseases ...
Superior vena cavaSuperior vena cava isolationElectrical activity in the superior vena cava (SVC) and right atrium (RA). Electrograms labeled "Penta" indicate signals from the multipolar PentaRay mapping catheter (Biosense Webster, Diamond Bar, CA) within the SVC. Electrograms labeled "CS" indicate...
Total body scans performed after intravenous injections of labeled albumin microspheres indicated 65 percent right to left shunting of left arm venous return but only 9 percent shunting of right arm venous return, findings that are diagnostic of left superior vena cava to left atrial communication....

At the light microscopic level, all spermatozoa appeared to be labeled over the dorsal portion of the head, whereas tails were negative. This observation was confirmed using scanning electron microscopy. A large number of particles were seen on the external surface of the plasma membrane covering ...
