[Radiation exposure during digital subtraction angiography (DSA) of the kidney and aortic arch].
The somatic and genetic radiation dose from DSA and conventional film angiography were compared, using an Anderson-Rando phantom. The dose is greatly influenced by the method of examination; for the examination of the aortic arch in a male, DSA reduces it by a factor of 4 as compared with conventional angiography, in a female by a factor of 11. For renal DSA (PA) somatic dose for a man is 25 times greater, and for a woman 18 times greater, than with conventional angiography (AP). Renal DSA should therefore be carried out in an AP projection in order to reduce the bone marrow dose in the lumbar spine.
