 Magnetic resonance angiography (MRA) is a new technique using high sensitivity to flowing material in the scanning plane. There are mainly two methods of MRA, phase contrast and time of flight. Former method is useful to detect fast and slow flow and to reflect flow velocity. Cine mode display of flow pattern is also available. Latter method is useful to get morphological information of arterial structure rather than venous structure.

 Rephased MRA with Gd-DTPA administration demonstrated contrast enhanced lesions and subacute phase of bleeding which was hardly detected by DSA or conventional angiography. This feature may be one of merits of MRA.
