  		Fig. 5. —Trend line graph shows emergency department imaging resource use, measured as unadjusted relative value units, from 1993 to 1998. Note sharp increase in use of CT ({blacksquare}), which was attributed to changes in practice patterns, compared with angiography ({square}), diagnostic radiology ({diamond}), and MR imaging ({diamondsuit}).
