[Transluminal visualization of intra-aneurysmal blood flow with transluminal flow imaging of three-dimensional MR angiography].
As a preliminary investigation, we report transluminal flow imaging with perspective volume rendering of magnetic resonance angiography in patients with unruptured cerebral aneurysms. Selective change in signal intensities, based on using a square curve, was superimposed onto the transluminal image of the vessel and aneurysmal walls. This imaging technique provided direct visualization of flow-related information within the aneurysm in relation to its morphologic features. Transluminal flow imaging of three-dimensional magnetic resonance angiography may be a useful adjunct for the evaluation of intra-aneurysmal blood flow in clinical cases.
