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 ...

Transposition of the Great Vessels Manifested on Radionuclide Ventriculography
Clinical Nuclear Medicine, 2003Ventricular ejection fraction was evaluated in a 30-year-old man. At birth he underwent a Rashkind procedure and placement of a Waterston shunt, followed by a Mustard procedure at age 2 years. In the Mustard procedure, an oblique right atriotomy is created, the atrial septum is excised, a pericardial baffle is sutured to incorporate the pulmonary veins

Prognostic Value of Radionuclide Ventriculography After Myocardial Infarction
QJM: An International Journal of Medicine, 1980We have studied 50 consecutive patients who had sustained their first myocardial infarction. Using the noninvasive technique of radionuclide ventriculography, ventricular performance, as assessed by left ventricular ejection fraction (EF), was measured at rest just before discharge from hospital when patients were well and free from cardiac failure and

Exercise radionuclide ventriculography in evaluation of coronary artery disease
American Heart Journal, 1986The ability of radionuclide variables obtained at rest and at peak exercise to discriminate the number of stenosed (greater than or equal to 70% luminal diameter narrowing) major coronary arteries was evaluated in 296 patients undergoing supine exercise radionuclide ventriculography.
