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.

Unreliability of cardiothoracic ratio as a marker of left ventricular impairment: Comparison with radionuclide ventriculography and echocardiography.
At the study's outset, all patients had ejection fractions below 40%, as evaluated by radionuclide ventriculography.
The investigators noted that in earlier trials ejection fractions were determined echocardiographically rather than with radionuclide ventriculography.
Yancy stated, "Echocardiography or radionuclide ventriculography are extremely important, but not practical or cost-effective methods to guide frequent management decisions.
They are echocardiography, radionuclide ventriculography, magnetic resonance (MR) imaging, and EBCT.
Imaging technologies, including echocardiography and radionuclide ventriculography, are recommended to diagnose heart failure correctly; however, the guidelines stress that using these tests repeatedly to assess patients' response to therapy is inappropriate, and that it usually is more useful for clinicians to monitor response to therapy by questioning patients about their symptoms and their ability to carry out everyday activities, such as climbing stairs or walking.
