Ninety-six series of stereoscopic DSA utilized on forty-eight brain tumor patients were evaluated by comparison with subtracted magnified angiograms or independently. All stereoscopic DSA series had good or fairly good stereoscopic quality. Stereoscopic DSA was useful for the pre-operative diagnosis of brain tumors, such as menigniomas, pituitary adenomas, glioblastomas, neurinomas, etc.
Stereoscopic DSA was also useful for the evaluation of the post-operative states of these brain tumors. In the near future, stereoscopic DSA may replace many areas of conventional angiography for the diagnosis of brain tumors.
