Figure 5. Bar graph shows comparison of lower-extremity imaging protocols. Of note, the number of images signifies the total number obtained in both lower extremities combined. One refers to both lower extremities (hips to feet) together on one image. Two refers to each lower extremity (hip to foot) exposed separately. Four (A) refers to femur and lower leg together on one image and the foot on a separate image. Four (B) refers to the femur on one image and the lower leg and foot together on a separate image. Six refers to each lower extremity exposed separately with three exposures.
