Pinhole radionuclide ventriculography in small infants

American Heart Journal, 1986
Radionuclide equilibrium gated ventriculograms were performed in 23 infants before and after surgery for congenital heart disease using standard parallel hole general purpose collimation followed by a pinhole collimation technique to magnify images and improve spatial resolution.

Equilibrium radionuclide ventriculography in Duchenneʼs cardiomyopathy

Nuclear Medicine Communications, 1988
Rest and stress (handgrip) equilibrium radionuclide ventriculography was performed in 20 patients with Duchenne muscular dystrophy. The mean value of LVEF was normal, but two patients showed values below 35% and another two patients values over 70%. Mean regional wall motion values were less than 2 in lateral (posterior and inferior) and septal walls ...

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

Equilibrium Radionuclide Ventriculography in Single Ventricle

Clinical Nuclear Medicine, 1985
With the recent advances in pediatric cardiology and cardiovascular surgery, assessment of ventricular function in single ventricle complexes is becoming increasingly important. The serial assessment of ventricular function helps our understanding of the natural and unnatural history in these patients. Equilibrium radionuclide ventriculography is safe,

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%

Eventration of the Diaphragm on Radionuclide Ventriculography

Clinical Nuclear Medicine, 1998
A 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

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

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.

Role of radionuclide ventriculography in evaluating cardiac function

European Journal of Radiology, 1991
The 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
