1

benefits of x-ray

widely available
easy
excludes bowel obstruction/perforation

2

types of abdo X-ray

supine AXR
erect CXR

3

benefits of USS

easy, safe
clear visualisation of solid organs, free fluid, aorta, pelvis
Bowel – occasionally helpful
Correlate imaging with tenderness

4

benefits of CT

quick
accurate
allows better planning of surgery or intervention

5

drawbacks of CT

radiation exposure
renal impairment

6

benefits of MRI

no radiation
good soft tissue delineation esp in pelvis

7

drawbacks of MRI

takes a long time
contraindications/claustrophobia

8

when would you use MRI

use as a second line test in hepatic-biliary, small bowel and pelvis issues

9

key symptoms of acute appendicitis

periumbilical pain
nausea and vomiting

10

where does appendicitis pain localise

RIF

11

imaging in appendicitis

no role for X-ray
CT and USS are diagnostic
USS 1st, CT if this is inconclusive

12

incidence of acute diverticulitis decreases with age

false, increases with age

13

complications of acute diverticulitis

abscess
obstruction
perforation
fistulae

14

imaging acute diverticulitis

xray - exclude obstruction/perforation
CT with IV contrast = gold standard

15

CT findings acute appendicitis

appendiceal dilatation
wall thickening
thickening of the caecal apex

16

ureteric calculus presentation

loin to groin pain

17

imaging for ureteric calculus

non contrast CT - stones >1mm in size are visualised along with assoc changes

18

presentation of acute diverticulitis

left iliac fossa pain
unremitting pain with tenderness
possibly ill-defined mass
symptoms become more generalised with progression

19

what causes acute cholecystitis?

almost always secondary to gallstones

20

diagnosis of cholecystitis

one sign of inflammation (fever, WCC, CRP)
one local sign of inflammation (RUQ pain etc)
confirmatory imaging

21

imaging in acute cholecystitis

USS
CT can be false -ve
MRI if biliary tree dilatation

22

USS in acute cholecystitis

gallstones
GB wall thickening
local fluid

23

MR cholangiopancreatohraphy in cholecystitis

shows stone in common bile duct causing obstruction
stones in GB

24

what is emphysematous cholecystitis

air in gall bladder wall
(diabetics)

25

treatment options for cholecystitis

medical/conservative
interventional radiology (percutaneous)
ERCP if obstructed biliary tree
surgery

26

causes of small bowel obstruction

adhesions
cancer
hernia
gallstone ileus

27

pancreatitis presentation

acute onset of severe central epigastric pain
poorly localised tenderness and pain
exacerbated by supine positioning
radiates through to the back in some

28

blood test for pancreatitis

elevation of serum amylase

29

pancreatitis imaging

clarify diagnosis
assess severity and determine prognosis
detect complications
determine causes

30

US pancreatitis

identifies gallstones as cause
assess for other aetiologies
