QuestionAnswer
The respiration phase for the AP oblique projection of the lumbar spine is: Expiration
What is the central ray angle for the AP axial projection (Ferguson Method) of the lumbosacral junction? 30-35 degrees cephalad
The condition of the lumbar spine in which there is anterior displacement of one vertebra over another is termed: Spondylolisthesis
Where is the central ray directed for an AP lumbosacral spine? Iliac crest
When only the lumbar vertebrae (not Lumbosacral) are imaged in the AP projection, the central ray is directed ______ inches above the iliac crests. 1.5
The intervertebral foramina of the superior four lumbar vertebrae are situated how many degrees from the midsagittal plane? - 90 degrees
An alternate method of positioning the central for the L1-S1 lateral projection is: Parallel with the interiliac line
How many degrees is the body rotated for the AP oblique projection of the sacroiliac joint? 25 to 30 degrees
To demonstrate the zygapophyseal joints of the lumbar spine, MSP of the patient is rotated ____ degrees. 45 degrees
The central ray angle for an AP axial projection of the sacrum is: 15 degrees cephalad
What is the central ray centering point for an AP oblique lumbar spine? 2 inches medial to the elevated ASIS and 1 to 1.5 inches above the iliac crest
Which projection of the lumbar spine displays the vertebrae in the form of the “Scottie dog”? AP Oblique and PA oblique
Occasionally, a patient may have to be placed in the prince position for a sacrum radiograph, and a PA projection performed. What is the central- ray angle for this projection? 15 degrees caudad
On each side of the sacral base is a large wing like mass called the: Ala
How many vertebrae are there in the sacrum? 5
Where is the central ray positioned for a lateral sacrum? At the level of the ASIS and 3.5 inches posterior
Where is the central ray positioned for the lateral coccyx? - 3.5 inches posterior to the ASIS and 2 inches inferior - (Hook your finger on the ASIS and make an L, then line up at the end of the thumb)
Which 2 projections will demonstrate the right sacroiliac joint? AP oblique LPO position and PA RAO position
If the lumbar spine cannot be adjusted so it is horizontal for the lateral projection, the central ray ______ should be angled: 5 degrees for men, 8 degrees for women caudad
