A PA esophagus projection that demonstrates the esophagus to the right of the vertebral column
a. will also demonstrate the right SC joint superimposed by the vertebral column.
b. was obtained with the patient rotated into an RAO position.
c. was obtained with the shoulders at equal distances from the IR.
d. was obtained with the right side of the chest positioned at a greater OID than the left side.
Question 2
For a PA oblique esophagus projection (RAO position) with accurate positioning,
a. the patient is rotated until the midcoronal plane is at a 35- to 40-degree angle with the IR.
b. the central ray is centered to the esophagus at the level of T6 to T7.
c. an 11- 14-inch (28- 35-cm) IR is used.
d. the patient drinks barium before the exposure only.
