The results of anatomic and hemodynamic studies of the human internal jugular valve,
which is the only venous valve between the right atrium of the heart and the brain, have …

right atrium is proposed as a useful indicator of slow Page 1 1. On radionuclide venography,
the presence of jugular venous reflux may serve as an early sign of SVC syndrome …

Cerebral venous outflow impairment is known to produce cerebral dysfunction in many
clinical and animal studies. However, knowledge and understanding of the cerebral venous …

Objective: We evaluated the relationship between image degradation due to the reflux of
contrast agent into the major neck veins and use of a left-arm injection site during computed …

The purpose of this study was to evaluate left brachiocephalic venous stasis and its
relationship to suboptimal contrast‐enhanced carotid magnetic resonance angiography …

A case of isotopic jugular venous reflux, reaching the opposite jugular vein, is described.
Phlebography and aortography were simultaneously performed in this patient and showed …

Radionuclide cerebral imaging (RCI) is a commonly used technique for detection of
intracranial blood flow in patients with clinically suspected brain death. In 115 studies …

DISCUSSION Unilateral obstruction of an innominate vein, with patency of the superior vena
cava, has been de scribed most often in association with malignant tumor (1, 2). In addition …

The effects of injection site, age, and body position on cervical venous reflux during carotid
radionuclide angiography were studied. Adults injected via the left arm while supine were …

Objective: This study assesses if the arm of contrast infusion influences attenuation of the
main pulmonary artery in computed tomography (CT) angiograms to evaluate for pulmonary …
