[ RadSafe ] Medical x-ray vs. CAT scan

[Joel C.]

My wife recently had an x-ray; they were looking for a bone fracture.  The Dr. wasn't happy with the x-ray and ordered a CAT scan.  Is there any reason why drs. don't skip the standard "film" and go right to the CAT scan, if they suspect they need the extra resolution?  Do they have to show that the film isn't adequate first?  I know the film exposure is low, but if there's no benefit...
