Exam 3: Image Analysis of the Chest and Abdomen

A PA chest projection with accurate positioning demonstrates 1)10 or 11 posterior ribs above the diaphragm. 2)equal posterior rib length on both sides of the chest. 3)the manubrium superimposed by the fourth thoracic vertebra. 4)the scapulae outside the lung field.

A neonate AP chest projection demonstrates the left posterior ribs with greater length than the right posterior ribs. How should the positioning setup be changed to obtain an optimal projection?

To reposition a decubitus abdomen projection that demonstrates longer right posterior ribs and a wider right iliac wing,

A lateral chest projection demonstrates the posterior ribs separated by 2.5 inches (6.35 cm). The superior heart shadow does not extend into the anteriorly situated lung. How should the patient be repositioned to obtain an optimal image?

Which side of the patient is positioned against the imaging table or cart for an AP-PA chest projection (lateral decubitus position) to rule out a right side pneumothorax?

A right PA oblique chest projection (RAO position) corresponds with which AP oblique projection?

An AP axial chest projection (lordotic position) with accurate positioning demonstrates 1)the medial ends of the clavicles projected superior to the lung apices. 2)the lateral borders of the scapulae within the lung field. 3)equal distances from the vertebral column to the SC joints. 4)almost horizontal posterior and anterior portions of the first through fourth ribs.

For an AP axial chest projection (lordotic position), 1)the shoulders are positioned at equal distances from the IR. 2)the patient's back is arched until the midcoronal plane and IR form a 45-degree angle. 3)a 15-degree cephalad central ray angulation is used if the patient is standing erect. 4)the elbows and shoulders are rotated anteriorly.

A PA chest projection with poor positioning demonstrates the scapulae in the lung field and elevated lateral clavicular ends. How should the patient be repositioned for an optimal projection to be obtained? 1)Tilt the upper midcoronal plane away from the IR. 2)Depress the shoulders. 3)Coax the patient into a deeper inspiration. 4)Anteriorly rotate the shoulders and elbows.

A PA chest projection on a patient with a right side pneumothorax will demonstrate
