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 ...

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.

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).

Identification of right ventricular rupture by radionuclide ventriculography
Nuclear Medicine Communications, 1984Right ventricular rupture is rare. We report its identification by radionuclide ventriculography and subsequent confirmation by contrast angiography and at operation. The aetiology in this case was a primary cardiac malignancy.

Uncommon Breast Tumor Attenuation Artifact on Radionuclide Ventriculography
Clinical Nuclear Medicine, 2008A 39-year-old woman with locally advanced left breast cancer (T4 N0 M0) underwent equilibrium radionuclide ventriculography for baseline assessment of left ventricular function before neoadjuvant chemotherapy. The left ventricular ejection fraction was 76% at 75 beats per minute, without localized wall motion abnormality.

Software Phantom for the Synthesis of Equilibrium Radionuclide Ventriculography Images
2006 International Conference of the IEEE Engineering in Medicine and Biology Society, 2006This paper presents the novel design of a software phantom for the evaluation of equilibrium radionuclide ventriculography systems. Through singular value decomposition, the data matrix corresponding to an equilibrium image series is decomposed into both spatial and temporal fundamental components that can be parametrized.

Assessment of ventricular function in arterial hypertension with radionuclide ventriculography [PDF]
The American Journal of Medicine, 1988 Diastolic function of the left ventricle was assessed in 29 untreated patients with mild to moderate hypertension and in 21 normotensive control subjects using gated radionuclide ventriculography. In hypertensive patients, the time to peak filling rate was significantly longer (p less than 0.01) than that in control subjects, and first-third filling ...

Posttraumatic cardiac dysfunction: assessment with radionuclide ventriculography.
Radiology, 1986The authors studied 54 patients with multisystem trauma, including blunt chest injury, using combined dynamic first-pass and electrocardiographically (ECG) gated radionuclide ventriculography (RNV) to evaluate for posttraumatic myocardial dysfunction. Twenty-six of 54 (48%) patients had abnormalities of ventricular wall motion.

Usefulness of radionuclide ventriculography in assessment of coronary artery spasm
The American Journal of Cardiology, 1987Provocative tests that permit detection of coronary artery spasm are widely used in patients with ischemic syndromes. To assess the usefulness of radionuclide ventriculography combined with provocative tests for diagnosis of coronary spasm, the left ventricular (LV) response to exercise, hyperventilation and a cold pressor test was determined in 3 ...
