IVU Positioning Flashcards
What is the SID used for IVU images?
40”
Where is the CR for an AP IVU?
Enters the MSP perpendicular to the level of the iliac crest
How is the patient positioned for an AP IVU?
The patient is supine with no rotation
Where is the CR for an AP IVU if there is ureteral compression?
Enters the MSP perpendicular to the level of the ASIS
Why would a PA IVU be performed?
To compress kidneys/abdominal viscera, and remove air/gas obscuring anatomy
What breath are IVU images taken?
Suspended expiration
Where is the CR for an AP IVU if performed upright?
Enters the MSP perpendicular 2” below the level of the iliac crest
Why would an AP IVU be performed upright?
To demonstrate motility of kidneys and bladder
An AP IVU is generally performed at ______
Timed intervals
What are the structures seen for an AP IVU?
- Kidneys and lower portion of liver are visible
- Bladder and pubic symphysis included
- Intraabdominal calcifications or masses seen
Where is the CR for a 30-degree RPO/LPO IVU?
Perpendicular and 2” lateral to the midline on the elevated side at the level of the iliac crest
At what angle is the patient rotated for a 30-degree RPO/LPO IVU?
Depends on body habitus (hypersthenic patients require more rotation)
What structures are seen for a 30-degree RPO/LPO IVU?
- Bilateral visualization of the kidneys free from superimposition of the vertebral column
- The kidney on the side down is seen perpendicular to the IR, and is best demonstrated
- Kidney on up side is parallel with the IR
- Demonstrates contrast in the urinary system
Where is the CR for an AP bladder IVU?
Perpendicular to MSP entering at a level 2-3” above the upper border of the pubic symphysis
How is the patient positioned for an AP bladder IVU?
Supine with no rotation
