serial angiographic apparatus and twin roentgen tubes which are placed side by side at a specific distance for stereoscopic view, were connected to have "serio-STEREO-angiography" by means of usual single procedure of contrast injection. Twin roent-gen tubes were so synchronized with the serial angiographic apparatus, that every other film in the series is exposed by one of the twin tubes and the alternate films by the other of the twin tubes. In this way, film 1 and 2 are stereoscopic pair, film 3 and 4, 5 and 6, and so on are similarly stereoscopic. Strictly speaking, the pair films were exposed with some time interval (about 0.3 sec. in this apparatus), i.e., not simultaneously, however, they were prac-tically enough for stereoscopic view.

Stereoscopic observation of cerebral angiograms in cases of intracranial space taking lesion might be beneficial in neuroradiological studies, however, it would be extraordinary important in cases in which abnormal vascularities such as neoplastic, regenera-tive vessels, collateral circuits and vascular malfor-mations are visualized, as such abnormal vascularities are often difficult to study its anatomy even if biplane roentgenograms are taken. In near future, a pair of twin roentgen tubes will be synchronized with the biplane simultaneous serial angiographic apparatus to have multiple studies without multiply-ing the number of contrast injection.
