ventriculography

 [ven-trik″u-log´rah-fe]
1. radiography of the cerebral ventricles after introduction of air or other contrast medium. This study is no longer used to examine the brain; being replaced by CT and MRI.
2. radiography of a ventricle of the heart after injection of a contrast medium.

the display, by means of a stationary scintillation camera device, of the passage of a bolus of a rapidly injected radiopharmaceutical through the heart.

Planar radionuclide ventriculography (RVG) also commonly known as multigated acquisition (MUGA) cardiac blood pool scintigraphy has long been a simple and noninvasive method to assess ventricular function and, in particular, left ventricular ejection fraction (LVEF).
It is also important to emphasize that the approximate cost for SPECT radionuclide ventriculography is significantly lower than other alternatives such as cardiac MR and comparable to echocardiography.
There is limited data comparing the diastolic function parameters in the radionuclide ventriculography techniques.

The researchers noted that in earlier trials ejection fractions were assessed echocardiographically, not with radionuclide ventriculography.
The investigators noted that in earlier trials ejection fractions were determined echocardiographically rather than with radionuclide ventriculography.

Radionuclide ventriculography has poor edge detection, low count-to-noise ratios, and problems caused by overlap of the cardiac chambers.
Modalities such as radionuclide ventriculography, thallium imaging, and biplane ventriculography are unable to quantitate ventricular mass.
