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.

ven·tric·u·log·ra·phy

(ven-trik'yū-log'ră-fē),
1. Radiographic demonstration of the cerebral ventricles by direct injection of air or contrast medium; developed and described by Dandy in 1918. Compare: pneumoencephalography.
2. Demonstration of the contractility of the cardiac ventricles by recording serially the distribution of intravenously injected radionuclide or that of radiographic contrast medium injected through an intracardiac catheter.

It was concluded in another study comparing the visual EF and Simpson EF with the radionuclide ventriculography that the visual EF showed a better correlation, and in the cases where echogenicity is poor and the ventricular wall contours cannot be identified, the Simpson EF may be miscalculated.
However, left ventriculography revealed apical ballooning akinesis with basal hyperkinesis during systole and reduced ejection fraction [Figure 2].
Contrast ventriculography can also suggest a pseudoaneurysm when a narrow neck is detected but cannot always rule it out when an aneurysmal cavity is found [4].

However, there was a fistula network from the end of the left anterior descending artery and circumflex arteries to the LV cavity during end-diastole similarly a ventriculography pose (Figure 2).
His name comes from the Japanese, "tako tsubo" which translates to "octopus pot", a fishing jar with a narrow neck and wide base used to trap octopus, and describes the visual appearance of the heart on left ventriculography [1].
Of the thirty patients, LV aneurysm was defined as dyskinetic in 18 patients (dyskinetic group) and akinetic in 12 patients (akinetic group) by ventriculography. We retrospectively analyzed all relevant medical record and echocardiographic data gathered prospectively for the analysis.
However, the days of invasive diagnostic procedures such as pneumoencephalography, myodil ventriculography, echoencephalography, radionuclide scanning, and contrast angiography are now over and with the introduction of computed tomography (CT) and magnetic resonance imaging (MRI) scanning, imaging of brain SOLs has acquired new dimension whereby excellent anatomical detail in axial, sagittal, and coronal planes as well as tumor tissue characterization has become possible.
