Gated SPECT radionuclide angiography: what is the gain?

Noninvasive quantitation of valvular regurgitation by gated equilibrium radionuclide angiography.

R-wave synchronous equilbrium radionuclide angiography (RNA) is a noninvasive method that provides time-activity curve count information proportional to ventricular volumes and is used for relative volume comparisons within the left or right ventricle to derive the ejection fraction. Comparison of the ventricular count output between both ventricles may permit quantitation of the relative amoun...

Gated blood pool SPECT improves reproducibility of right and left ventricular Fourier phase analysis in radionuclide angiography.

OBJECTIVES The ventricular phase angle, a parametric method applied to Fourier phase analysis (FPA) in radionuclide ventriculography, allows the quantitative analysis of ventricular contractile synchrony. However, FPA reproducibility using gated blood pool SPECT (GBPS) has not been fully evaluated. The present study evaluates whether by using GBPS, the reproducibility of FPA could be improved o...

Radionuclide SPECT/CT in oncology

Radionuclide imaging employs radiolabelled tracers in the investigation of suspected cancer, subsequent staging, response assessment and the assessment of recurrence. Highly specific tracers, that target cellular receptors and metabolic pathways, are used in investigating patients with known or suspected cancers. Radionuclide imaging techniques have superior sensitivity compared to anatomic tec...

Radionuclide Pulmonary Angiography

A dramatic case of occlusion of the right pulmonary artery is presented. The diagnosis was clearly established by means of a lung scan and a radionuclide pulmonary angiogram. The entire course of the disease process was followed by radionuclide studies with a gradual but persistent return to normal. Due to the preciseness of the evidence presented, contrast angiography was not.thought necessary.
