36
Subjective data example
Patient states that she experiences extreme pain in upright position
- Objective data includes signs and symptoms that can be observed
- Subjective data relate to what patient feels & to what extent.
37
How can you tell the RPO position in the series of IVU images?
In RPO position, the right ilium is more "open" than the left. RPO position places the left kidney and right ureter parallel to IR. The urinary bladder contains considerable contrast, indicating that it is most likely a prevoid image.
38
When erect position is requested as part of an IVU, it is used to demonstrate
Kidney mobility
Erect position is requested as supplemental view to rule out nephroptosis. With patient erect, kidneys drop no more than 2 in. More marked dropping of kidney is termed nephroptosis, a condition that is due to loss of surrounding perinephric fat.
39
How can you tell whether the abdomen is taking PA or AP?
In PA, the ilia is more foreshortened, giving the pelvis a "closed" appearance, whereas AP the ilia and bladder area appears more "open".
40
Linear tomography (remember the image that shows the kidneys with the blurring effect)
Body section tomography functions to provide an image of a particular plane of tissues within the body, blurring out everything above and below the plane of interest.
Linear tomography is when X-ray tube moves in one direction while the xray IR moves in the opposite direction.
41
How does RPO position of IVU present?
Oblique IVU projections should be approx 30 degrees. When abdomen is obliques, kidney of the "down" side is perpendicular to the IR and its ureter is parallel to the IR. The kidney of the "up" side is parallel to the IR
42
Review the image of kidney
| what are renal pelvis, minor and major calyces, etc.
The renal pelvis is the proximal expanded end of the ureter lying within the renal sinus. The minor calyces receive urine from collecting tubules of renal pyramids and convey it to major calyces which empty into renal pelvis
43
What is Wilm's tumor? What examination would be appropriate for this?
Tumor of kidney. It's most common childhood renal tumor, usually affecting only one kidney.
IVU would be appropriate
44

45
What should you do if you discover while taking patient history that the patient scheduled for an IVU takes meteor in hydrochloride daily?
Proceed with examination if kidney function is normal
| Instruct patient to withhold metformin for 48 hrs after examination
46
Why do people use glucophage (metformin hydrochloride)?
To lower blood glucose level in patients who have type 2 diabetes. Patients on metformin may have intravascular iodinated contrast studies if their renal function is within normal limits.
(Iodinated media together with metformin could induce renal failure)
47
During IV urography, the prone position generally is recommended to demonstrate
The filling of ureters and the renal pelvis
48
How do the kidneys lie in posterior portion?
Kidneys lie obliquely in posterior portion of trunk with their superior portion angled posteriorly and their inferior portion and ureters angled anteriorly. To facilitate filing of most anteriorly placed structures, patient is examined in prone position
49
The procedures used to demonstrate renal function include
IVP, descending urography, infusion nephrotomography are functional urinary studies because the contrast medium is introduced intravenously and excreted by the kidneys
Retrograde urography isn't considered a functional study of urinary system. It involves introduction of contrast medium into kidneys via catheter, demonstrating structure not function
50
During IVU, the RPO position is used to demonstrate
Left kidney parallel to IR
| Right kidney perpendicular to IR
51

53
Which of the following involve(s) intentional misconduct?

54
To "excuse" suboptimal images, a radiographer makes a note on exam requisition claiming that patient "was uncooperative" radiographer can legally be found guilty of
Libel (written defamation)

63
Exposure factors of 100 kVp and 6 mAs are used with a 6:1 grid for a particular exposure. What should be the new milliamperes-seconds value if a 12:1 grid is substituted?
```
10 mAs
Factor for grid ratio:
No grid = 1 x original mAs
5:1 grid = 2 x orig mAs
6:1 grid = 3 x orig mAs
8:1 grid= 4 x orig mAs
12:1 grid = 5 x original mAs
16:1 grid = 6 x orig mAs
Grid conversion formula is mAs1/mAs2 = grid factor 1/grid factor 2
Substituting the unknown for the problem above: 6/x=3/5 -> 3x= 30 so x =10 mAs
```
