Answer 5

Center of IR to level of iliac crests, with bottom margin at symphysis pubis

Question 6

What is the placement of the CR in AP projection - supine position of the abdomen?

Answer 6

CR perpendicular to and directed to center of IR (to level of iliac crest)

Question 7

In AP projection- supine of the abdomen, A tall hyposthenic or asthenic patient may require _________ —one centered lower to include the symphysis pubis and the second centered high to include the upper abdomen and diaphragm

Answer 7

2 images placed lengthwise

Question 8

This projection is less desirable than AP if
the kidneys are of primary interest because of the increased object image receptor distance
