Pediatric Radiology



COMMENT ON NORMAL CHEST:

� Plain X-Rays chest post-anterior view .

� The patient is centralized.

� Normal bony structures.

� Central mediastinum.� Normal cardio-thoracic ratio & cardiac position .

� Both lung f ields are clear with normal hilar shadow.

� Both costopherenic recesses are clear with normal cardio-pherenic angle.



NORMAL



Remember in each case:

1. Obtaining Clinical history.

2. Proper technique. i.e. Good exposure

3. Patient position i.e. centralized or not?.

4. Orientation of the f ilm , i.e. lef t or right

marked.5. Recognition of f ilm artif acts.
