Should not alter clinical vascular imaging; hypothesis-generating for diastolic perfusion mechanisms and requires prospective validation.
Observational (n=31)
Cine MR velocity mapping demonstrates that retrograde flow in the aorta and extremity arteries contributes substantially to diastolic perfusion of internal organs.
Bogren et al. (1994) conducted an observational in Healthy (n=31). Cine magnetic resonance (MR) velocity mapping was evaluated on Antegrade and retrograde flow in the aorta and major arterial pathways. Cine magnetic resonance velocity mapping in 31 healthy subjects revealed retrograde flow in the aorta and extremity arteries, but no retrograde flow in arteries supplying internal organs.
