Appendix 1: Rules for Reding Peditric X-Rys* Red the ABCS: A = domen, B = one, C = chest, S = soft tissue 1. On every chest film, red the dominl portion s you would red n dominl film. 2. Knowledge of ntomy is the key to correct rdiogrphic dignosis. 3. The irwy should e visile on ll norml chest films. 4. A mss must e seen in two plnes. 5. An esophgrm must e performed in ny child with unexplined respirtory disese. 6. In unilterl hyperexpnsion of the lungs, you must see how the ir moves. Air must move in nd out of ech lung. Medistinl position is criticl to this determintion. 7. The hert nd liver re trnsprent orgns. 9. The dominl exmintion should include minimum of three views: supine, prone, nd erect. 10. On every dominl exmintion, evlute the chest s if you were looking t chest film. 11. In ostruction of the lumen, there should e proximl distention. 12. Try to find the effects of the mss on djcent orgns on ech dominl film. Drw the mss, if necessry. 13. After the mss hs een defined, find the center of the lesion. Then consider ll structures, gross nd microscopic, ner the center of the lesion s possile sources of the mss. Think skin to skin. 14. When viewing n extremity, try to imgine the ppernce of the ptient. An excellent exmple is owed legs or knock knees. 15. The periosteum is normlly not seen. 8. Alwys review ll old films to properly ssess the new one. Sutle findings cn esily e missed when single previous exmintion is reviewed. * These rules were dopted from Joseph O. Reed, MD, chief of peditric imging t Children s Hospitl of Michign from 1957 through 1987. Throughout this text we include these fundmentl concepts, which were used dily in his teching sessions.
