Radiation exposure to patients undergoing percutaneous coronary interventions: are current reference values too high?
This study, carried through by consistent use of radiation-reducing techniques, enables a reliable scoring of patient radiation exposure according to complexity and target vessel of the intended PCI. Our 95th percentiles for elective PCI, for recanalizations of chronic occlusions, and for emergency PCI advise reference levels of 22, 32, and 42 Gy.cm(2) for DAP, of 16, 25, and 24 min for T(F), and of 400, 600, and 700 cinegraphic frames, respectively.
In our study, rural students believed they were less likely to be accepted into medical school than urban students, and fewer rural students felt that medicine was promoted as a potential career choice. Our results may be explained by a lack of role models or perhaps by financial barriers, although further research is needed.
