Unilateral Breast Uptake on Radionuclide Ventriculography

Clinical Nuclear Medicine, 2014
Gated equilibrium radionuclide ventriculography is frequently used to measure the left ventricular ejection fraction. We report a case of unilateral breast activity resulting in significant underestimation of the left ventricular ejection fraction, which mimicked a left ventricular aneurysm, pseudoaneurysm, or an intrathoracic vascular mass. Unilateral

Exercise radionuclide right ventriculography in children

Pediatric Cardiology, 1987
Supine 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%

Radionuclide ventriculography

2017
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

Medial Splenic Tubercle Potential Radionuclide Ventriculography Pitfall

Clinical Nuclear Medicine, 1985
Blood pool activity in a medial splenic tubercle produced an apparent apical wall motion abnormality during radionuclide ventriculography.

Lymphomatous intracardiac mass detected by radionuclide ventriculography

International Journal of Nuclear Medicine and Biology, 1985
A 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

1983
Developments 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 ...

First-pass radionuclide ventriculography in conscious dogs

Scandinavian Journal of Clinical and Laboratory Investigation, 1987
Trained, 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.

Optimizing sequential biventricular pacing using radionuclide ventriculography

Heart Rhythm, 2005
Biventricular pacemakers are usually programmed with the default setting of synchronous biventricular pacing, although the ventricles may be paced sequentially. Whether this parameter is important for optimizing resynchronization therapy is not clear.The purpose of this study was to investigate whether sequential pacing acutely improves left ...

The Declining Specificity of Exercise Radionuclide Ventriculography

New England Journal of Medicine, 1983
Although 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 ...
