1

What is the modality of choice for assessing the adrenal glands?

Abdominal Ultrasound

Hypoechoic to surrounding fat; thin hyperechoic capsule; right adrenal is often more difficult to image in a dog due to overlying bowel gas

Normal adrenal glands have a diameter of <7 mm, require high resolution probes and ideal conditions

2

What anatomical structure is indicated by the red arrow?

Small Intestine

3

Jejunal intussuception: detected or not detected?

(the probe is positioned over the mid-central abdomen on the ventral abdominal body wall)

Detected

4

Splenic torsion: detected or not detected

Detected

Splenic torsion is most common in large and giant-breed deep-chested dogs. The spleen twists on its pedicle and occludes venous return. You may notice a C shape on lateral radiograph. The fundus will be displaces caudally and medially (tension on the gastrosplenic ligament)

**Gas bubbles may indicate anaerobic bacteria**

5

Hydronephrosis: detected or not detected?

(the probe is positioned over the left ventral abdominal body wall just caudal to the last rib)

Detected

6

Which is more sensitive for determining hepatomegaly: radiographs or ultrasound?

radiographs

7

T/F: On radiographs, the normal canine prostate gland may be minimally visible, but the prostate gland is essentially never seen in the cat

True

8

Identify the anatomic structure indicated by the red arrow:

portal vein

9

Pneumothorax: detected or not detected?

Detected

10

What is the earliest age of gestation at which mineralized fetal skeletons may be evident in abdominal radiographs of a pregnant female cat

~35 days

11

T/F: The normal uterus is difficult to impossible to detect on normal survey radiographs

True

12

Ureteral ectopia: detected or not detected?

Not detected

13

What is the most common type of prostatic neoplasia?

adenocarcinoma

**usually responds quite well to radiation therapy**

14

What is the modality of choice to evaluate the uterus?

Ultrasound

Ultrasonography can detect disease and pregnancy before radiographic or palpable changes are found

15

What are we observing in this hepatic ultrasound?

Portosystemic shunt

Now with added Doppler - fancy!

16

Acoustic shadowing: detected or not detected?

Not detected

17

Enlarged esophagus: detected or not detected?

Detected

18

Hepatomegaly may shift the gastric axis in what direction?

caudally

19

What anatomical structure is indicated by the red arrow? 

(The probe is parallel to the axis of the spine and is located on the ventral body wall at the xiphoid)

portal vein

20

T/F: Most of the caudal margin of the liver is usually not detected as it silhouettes with the stomach's wall and other adjacent organs

True

21

What is considered the most reliable radiographic indicator of splenomegaly?

rounded or blunt margins

22

Paraprostatic cyst: detected or not detected?

Detected

 

 

 

...the picture is labeled

23

Compartmentalization: detected or not detected?

Detected

24

What anatomical structure is indicated by the blue arrow? 

(The probe is parallel to the axis of the spine and is located on the ventral body wall at the xiphoid)

liver

25

Double Bubble Sign: detected or not detected?

Not detected

26

__________ is the most common cause of prostatomegaly

benign prostatic hypertrophy

27

Acoustic enhancement: detected or not detected?

Not detected

28

T/F: Radiography is a very good way to assess changes in the external anatomy of the kidneys

True

29

T/F: If the adrenal glands are mineralized in the dog, it tends to be incidental

False

If the adrenal glands are mineralized in the cat, it tends to be incidental

If the adrenal glands are mineralized in the dog, neoplasia is more likely

30

What is the modality of choice to diagnose splenic torsion?

Ultrasound

Spleen has enlarged lacy pattern; no blood flow (doppler); thrombosis of veins (grey rather than black)
