abdominal radiograph? - ANSWERS-Lower border of liver, psoas
muscles, kidneys, ribs, transverse processes of lumbar spine.
What is the recommended technique for geriatric patients in abdominal
imaging? - ANSWERS-Short exposure time and reduced technique; may
not use a grid.

REVIEW
What should be included in an acute abdominal series? - ANSWERS-PA
erect chest, AP erect abdomen, AP supine abdomen.
What are the evaluation criteria for an AP erect abdomen? - ANSWERS-
Air-filled stomach and bowel segments, bilateral diaphragm, no motion,
no rotation.
What is the purpose of upright chest positioning? - ANSWERS-Allows
diaphragm to move down, demonstrates air-fluid levels, prevents
engorgement of pulmonary vessels.
What is the ideal degree of inspiration for chest X-rays? - ANSWERS-
Exposure taken on the second full breath, ideally showing 10 posterior
ribs above the diaphragm.
What is the CR entry point for a PA chest X-ray? - ANSWERS-
Perpendicular at T7 on the mid-sagittal plane (MSP).
What is the evaluation criteria for a lateral chest X-ray? - ANSWERS-
Entire lung field from apices to costophrenic angles, no motion, no
rotation.

REVIEW
What is the significance of the left lateral chest position? - ANSWERS-
Places the heart as close to the IR as possible to decrease unwanted
magnification.
What should be done to minimize rotation during positioning? -
ANSWERS-Ensure the patient is centered and in a balanced stance with
weight evenly distributed.
What is the recommended exposure time to reduce motion in the GI
system? - ANSWERS-Use a short exposure time.
What anatomical structures should be visible in a normal CXR? -
ANSWERS-Air-filled trachea, lung markings, heart, great vessels, bony
thorax.
What is the purpose of the bony thorax in the respiratory system? -
ANSWERS-It serves as a protective framework for the respiratory
organs.
