What imaging protocol and findings are expected for suspected small bowel obstruction?
Answer: Acute abdominal series showing dilated loops over 3 cm, differential air-fluid levels, absent colonic gas
The acute abdominal series includes supine, erect abdomen, and erect chest.
What is the PA axial (Lordotic) chest projection used for?
Answer: Projects clavicles above lung apices to visualize apical pathology
The lordotic projection clears the clavicles from the apices for apical lung assessment.
How do gallbladder imaging positions differ between radiography and ultrasound?
Answer: Radiography uses oblique positions to separate gallbladder from spine; ultrasound uses supine with liver as acoustic window
Different modalities have different optimal positions based on their imaging physics.
What is the purpose of the left lateral decubitus position for abdominal radiography?
Answer: Detect small amounts of free air rising to the right flank with horizontal beam
Free air rises to the non-dependent side when the patient lies on their left side.
What is the purpose of double-contrast barium enema technique?
Answer: Coat mucosa with barium while air distends the lumen for detailed mucosal pathology visualization
Thin barium coating highlights surface abnormalities while air distension provides contrast.
What is the standard imaging protocol for suspected pneumothorax?
Answer: Erect PA chest on full expiration to increase contrast between collapsed lung and pleural air
Erect PA on expiration makes the pneumothorax proportionally more visible.
