| Question | Answer |
| What is demonstrated on an AP abdominal radiograph? | size and shape of liver, spleen, kidneys, intraabdominal calcifications, evidence of tumor masses |
| What is the CR entry for a supine AP abdomen (KUB)? | perpendicular to the IR at the level of the iliac crests (L4) |
| What is the CR entry for an upright AP abdomen? | horizontal entering 2” above the crests |
| Why would we do an upright abdomen as opposed to a KUB? | for free air, must include the diaphragm |
| Why would we do a PA abdomen in place of an AP? | when the kidneys are not of primary concern, a PA projection greatly reduced pt. gonadal dose |
| When performing a decubitus abdomen what steps should be taken to ensure fluid levels are accurately demonstrated? | allow the patient the lay for a few minutes before the exposure is taken, and wait a couple seconds after exhalation for the exposure to allow fluids to settle |
| What is the pt. position for a decubitus abdomen? | pt. lays on L. side, flex knees and extend arms. Allow fluid to settle |
| Why must a decubitus abdomen be done on the left side? | so that air in the fundus is not mistaken for free air |
| What is the CR entry for a lateral decubitus AP abdomen? | horizontal, perpendicular to the center of the IR, entering at the level of the iliac crests |
| Where should the CR be directed if the diaphragm must be demonstrated? | 2” above the level of the crests |
| Where should the CR be directed for a cross table decubitus abdomen? | entering the MCP 2” above the crests |
| How should a decubitus abdominal film be marked? | mark the side up |
| What are the main evaluation criteria points for a KUB? | pubic symphysis to upper abdomen included, proper patient alignment, no patient rotation, soft tissue grays demonstrate necessary anatomy |
| What are the main evaluation points for an upright abdomen? | pubic symphysis to upper abdomen included, proper patient alignment, no patient rotation, soft tissue grays demonstrate necessary anatomy, diaphragm without motion, density similar to KUB, appropriate marking (upright). |
| What evaluation points indicate proper patient alignment? | centered vertebral column, ribs hips and pelvis equidistant to edges of radiograph |
| What evaluation points indicate no patient rotation? | spinous processes centered over lumbar vertebrae, ischial spines symmetric, alae symmetric |
| What evaluation points describe the necessary demonstrated soft tissues? | lateral abdominal wall and properitoneal fat layer, psoas muscles lower border of the liver and kidneys, inferior ribs, transverse processes of L-spine, R or L marker visible and out of anatomy |
