Flashcards in Renal Soft Tissue Ocular DVT Deck (29):
1

Gerota's facia

Surrounds kidney and perinephric fat

2

What view of the kidney is ideal for visualizing the collecting system?

Coronal plane

3

The transverse view of the kidney must include...

The renal pelvis

4

The collecting system should appear ... on ultrasound.

Anechoic

5

If collecting system of kidney is echogenic think

Pus, stone, blood

6

What type(s) of hydronephrosis extends into the calyces?

Moderate and severe

7

What is a urinoma?

Also known as parasternal pseudocyst, an encapsulated collection of extravasated urine which can cause lipolysis of the surrounding fat with resultant encapsulation of the urine

8

Chronic hydronephrosis is distinguished from a more acute process by...

Thinning of the renal parenchyma

9

Dromedary hump

Cortical bulge on the lateral aspect of the kidney with the same echogencity of the normal parenchyma

10

Junctional fold

Wedge-shaped hyperechoic defect in the anterior aspect of the kidney near the junction of the upper and middle thirds

11

Columns of Bertin

Prominent column of cortical tissue that protrudes into the renal sinus and can simulate a mass

12

Twinkle artifact

Can aid in identifying distal ureteral stones

13

Emphysematous cystitis

Look for dirty shadowing/ring-down in non-dependent areas

14

If suspect obstructive uropathy and risk for AAA....

Scan aorta

15

Ultrasound is used to detect .... not cellulitis.

Drainable fluid collections

16

What must be visualized on an abscess in order to have a complete exam?

The base. If not seen then further evaluation required.

17

What sonographic findings are consistent with abscess?

Swirling of internal contents and absence of color flow

18

Vitreous hemorrhage on ultrasound

Thin echogenic band that floats freely with eye movement

19

Retinal detachment on ultrasound

Remains attached posteriorly with eye meovement. High echogenicity. Visible with low gain, low mobility, attached to optic disc

20

Posterior vitreous detachment

May or may not be attached to optic disc, lower echogenicity, disappears with low gain, high mobility

21

Choroid also detachment on ultrasound

Scalloped appearance, shallow can be treated non-op vs. oppositional treated operatively

22

Optic sheath nerve diameter normal diameter

Up to 5 mm as measured 3 mm posterior to the globe

23

Anisotropy

Scanning tendons at any angle other than perpendicular will result in loss of the normal hyperechoic appearance

24

What fills in the tendon gap in a complete tear?

Hemorrhage or Kager's fat pad

25

Presence of intact ... at the medial aspect of the Achilles' tendon may simulate intact Achilles' tendon

Plantaris tendon

26

What vessels are visualized on DVT scans?

Common femoral vein before and after take off of greater saphenous, superficial femoral vein, deep femoral vein, and popliteal until trifurcation. Deep femoral vein will be lost but follow the superficial femoral vein. Make sure there is no duplication.

27

If vein is smaller than artery in femoral system, what should you suspect?

Femoral vein duplication

28

The superficial femoral vein is also called...

Femoral vein

29

Anechoic structure with curve and taper found in popliteal fossa

Baker's cyst
