The appropriate position to demonstrate the zygapophyseal joints of the lumbar spine is:

• 45 degree oblique

• 30 degree oblique

• AP Axial

• Lateral

An image of an AP axial sacrum reveals that it is foreshortened and the sacral foramina are not clearly seen.  The patient was in an AP supine position and the CR was angled 15 degrees caudad.  What was the error?

• The CR is angled in the wrong direction

• The CR angle is too shallow, needs to be increased to 25 degrees

• The CR angle is too steep, needs to be decreased to 5 degrees

• There should be NO angle, CR should be perpendicular to the IR

Name the view.

• RPO Lumbar

• Lateral Lumbar

• LPO Lumbar

• AP Lumbar

Which is an lateral projection of humerus radiograph?

• 
• 
• 
• 

A patient is lying supine.  The x-ray tube is directed horizontally with the CR entering the right side of the body.  What is the name of the position?

• Right lateral decubitus

• Left lateral decubitus

• Dorsal decubitus

• Ventral decubitus

The appropriate centering point for an AP projection of the lumbosacral region is

• midpoint between the xiphoid tip and sternal notch

• 2 inches superior to the public symphysis

• at the level of the iliac crest

• 1 inch superior to the iliac crest and 2 inches medial to the ASIS

If the distance between the ASIS and tabletop is less than 19 cm, the correct tube angle for an AP knee is:

• 5 degrees caudad 

• 5 degrees cephalad 

• perpendicular 

• 0 degrees caudad 

A broad shouldered patient comes to the radiology department for a routine cervical spine series. The lateral projection demonstrates only the C1-C5 region. The radiologist needs to see C6-T1. What additional projection can be obtained to demonstrate this region?

• LAO

• Grandy Method

• AP Axial Oblique Projection (Pillars)

• Cervicothoracic (Swimmer’s) lateral projection

The suprasternal, manubrial, or jugular notch all correspond to the level of:

• T2-3

• T1

•  

  T4-5

• C7

A patient has an injury to their left anterior upper ribs. Which would best demonstrate that area?

• PA and RAO

• AP and LAO

• AP and RPO

• PA and LPO
