Flashcards in Radiology [3] Deck (16):
1

Identify

calcification of GS

- Typicallly laminated due to forming over long periods of time and faceted due to being multiple and

2

Pancreatic calcification
- BUZZ for chronic pancreatitis

3

air can be seen above the diaphragm if the pt has a ____

Hiatal hernia

4

Small or large intestines?

Valvulae conniventes

In small bowel - folds go all way around bowel
- Sm bowerl should be in midddle
(look for haustra in colon)

5

Small or large intestines?

Haustral folds

interrupted by teniae coli
does not go all the way around

Large intestines

6

Small vs large intestine

Haustra vs Valvulae conniventes
Large vs Small Int

7

Bowel obstruction

rule

proximal bowel will distend --> dilatation of bowel
(3,6,9)
<3-Small bowel
<6cm transverse colon
<9cm cecum

8

What imaging is most sensitive for free air

upright PA CXR
- look underneath diaphragm

When looking for free air, it will be located in the most "non dependent space" so important to note the position of patient when x-ray was obtained.

9

reflux esophagitis
- "granular"

10

reflux esophagitis with ulcers and hiatal hernia

11

peptic stricture of esoph & hiatal hernia

12

Candida esophagitis

- Note how plaques have a linear configuration and are separated by normal intervening mucosa.

13

double-contrast esophagography: 
shaggy esophagus of fulminant Candida esophagitis in a patient with AIDS.
This shaggy contour results from innumerable pseudomembranes and plaques, with trapping of barium between lesions.

14

Which part of the stomach is typically anterior

fundus

15

Types of barium enema+ indication

double contrast: rectal bleeding, poyps, cancer, IBD

Single contrast: fistula or sinus tract, pt unable to tolder double

Water soluble contrast: risk for intestinal perforation, therapeutic for disimpaction

 

BE: evaluates colon + rectum

16

When is CT without contrast useful?

When is CT with IV contrast useful?

detection of renal stone/hemorrhage

With contrast:
- ischemic, infectious, or inflammatory disease, trauma, tumor
- arterial, venous, portal venous
