  • Title: [Transluminal imaging of three-dimensional CT and MR angiograms for transluminal observation of angioarchitecture of cerebral aneurysms].
    Author: Yokoyama C, Ohsako C, Satoh T.
    Journal: Nihon Hoshasen Gijutsu Gakkai Zasshi; 2002 Dec; 58(12):1676-81. PubMed ID: 12577029.
    Abstract:
    To investigate the angioarchitecture of cerebral aneurysms, we studied various opacity curves to select specific volume data of CT and MR angiograms from the opacity charts of CT density or MR signal intensity distribution. We developed the method of transluminal imaging of CT and MR angiograms; the vessels and aneurysms were depicted transluminally through spaces between the rings of the vessel walls. Two cases of unruptured cerebral aneurysms were studied by transluminal imaging of three-dimensional CT and MR angiograms. The technical aspects of transluminal imaging and characteristics of volume data, obtained by CT and MR angiograms, were discussed.
