Abstract
Objective To carry out further analysis and assessment of the radiation risk from DSA examinations and related factors. Methods All the online radiation dose values and associated parameters of the 107 patients examined were collected for purpose of statistical analyses according to their classification. Results The analyses of DSA examinations indicated: for coronary angiography, DAP was (22 285.5±18 682.7)μGy·m2, ESD was (2 942.1±2 557.3) mGy; for head angiography, DAP (25 929.6±8 302.7) μGy·m2, ESD (1 288.8±682.3) mGy; for abdominal angiography, DAP (12 129.7±10 646.1) μGy·m2, ESD (730.1±584.7) mGy. Conclusions Among total accumulated radiation dose, the dose arising form coronary angiography is the highest, followed by the head angiography, and the dose from abdominal angiography is the lowest.
