Comparative analysis of dynamic contrast-enchanced (3DFFE) and time-of flight (3D TOF) magnetic resonance angiography in the diagnostics of aneurysms and malformation of cerebral vessels

Development and approbation of effective methods of dynamic MR angiography with digital subtraction by mask of non contrast images, and also comparative analysis of diagnostic capabilities of 3DTOF and 4DMRA constitute the aim of this study. Retrospective study on archived data of the combined use of timeofflight 3DTOF and 4D MRA was performed for the diagnosis of the most common vascular disease of the brain. According to the principle of one window within one magnetic resonance imaging there is a possibility of diagnostics and verification of the most common vascular lesions such as arterial aneurysms and vascular malformations.
