Exercise radionuclide right ventriculography in children
Pediatric Cardiology, 1987Supine exercise equilibrium radionuclide right ventriculography was performed in 13 children (8-18 years) with hypercholesterolemia. Phase analysis was used to construct right ventricular regions of interest, and a peri-right ventricular region was used for background correction. Right ventricular ejection fraction at rest and exercise was 50.5 +/- 9.2%

The Declining Specificity of Exercise Radionuclide Ventriculography
New England Journal of Medicine, 1983Although exercise radionuclide ventriculography was initially reported to be a highly specific test for coronary-artery disease, later studies reported a high false-positive rate. To verify this turnabout, we analyzed the responses in 77 angiographically normal patients; 32 were studied from 1978 to 1979 (the early period), and 45 from 1980 to 1982 ...

Eventration of the Diaphragm on Radionuclide Ventriculography
Clinical Nuclear Medicine, 1998A 67-year-old man was referred for a radionuclide ventriculogram because of progressive dyspnea. Although the radionuclide ventriculogram demonstrated normal systolic left ventricular function, a large focus of extracardiac activity lateral and posterior to the heart was unexpected.

Radionuclide ventriculography (RNV) was the first reliable non-invasive method of assessing left ventricular (LV) function, and established nuclear cardiology as a clinical discipline. The subsequent development of other imaging modalities, particularly echocardiography, has led to a sharp decline in the number of studies performed, but RNV still has a

Role of radionuclide ventriculography in evaluating cardiac function
European Journal of Radiology, 1991The role of nuclear cardiology techniques for evaluating cardiac function has become increasingly important among other diagnostic techniques. The current status of radionuclide imaging of left and right ventricular function allows accurate diagnosis of cardiac patients with both coronary and noncoronary disease. The combination of gated first-pass and

First-pass radionuclide ventriculography in conscious dogs
Scandinavian Journal of Clinical and Laboratory Investigation, 1987Trained, chronically instrumented, conscious dogs were used to study the function of the left ventricle by first-pass radionuclide ventriculography (RNV). Six dogs were trained prior to a sterile left thoracotomy, where a left atrial catheter was implanted.

Lymphomatous intracardiac mass detected by radionuclide ventriculography
International Journal of Nuclear Medicine and Biology, 1985A case of non-Hodgkin's lymphocytic lymphoma with cardiac involvement shown as an intracardiac-filling defect on the radionuclide ventriculogram is presented. The non-invasive diagnostic methods for cardiac lymphoma work-up are discussed. The known causes of cardiac-chamber filling defect(s) are reviewed.

Radionuclide Ventriculography to Evaluate Myocardial Function
1983Developments over the past decade have allowed one to visualize the right and left ventricles using radionuclide techniques and to study the influence of a wide range of physiologic, pharmacologic and surgical interventions on global and regional ventricular function thereby providing important diagnostic insight and improved therapeutic capabilities ...

Influences on evaluability of radionuclide ventriculography in chemotherapy patients
Nuclear Medicine Communications, 1998Radionuclide ventriculography (RNV) is an established method of evaluating cardiotoxic side-effects of chemotherapy. The image quality of RNV depends on labelling yields obtained after red blood cell (RBC) labelling with 99Tc(m)-pertechnetate and has an influence on the evaluation of the left ventricular ejection fraction (LVEF).
