DSA GIGU Imaging Flashcards
KUB flat plate or scout film is what
Kidney, Ureter, Bladder
Not very accurate since gas obstructs these organs
SCREEN FOR = acute abd disease
Quick
KUB speckled grey areas are
Feces with some air in it
*complete black is not good= obstruction becuz its just air
Acute ABD series flat and upright AP chest
When do I do this
Can see what
ADB pain, distention, X bowel sounds
Can see air under diaphragm, obstruction, fractures, nasogastric tube placement
Pneumoperitoneum
Air under diaphragm
= bowel perforation + peritonitis present
FAST exam
Fluid or blood collecting in abnormal places
If trauma
US is about what 4 things
- Size
- Shape
- Inflammation
- Stones
* solid = white, liquid = black
HIDA scan
Looking at Liver and bile excretion
Nuclear tagged material so avoid in Pregnancy
*check for gallbladder function
= you see if the GB fills and if it doesn’t = obstruction
= otherwise you can see function of GB or inflammation
When do you not order US
Gas or obstruction in BOWEL
+ scan for Cholecystitis
White spot in gallbladder + acoustic shadow that it makes
On US
HIDA and CCK injected
GB FUN filling then inject CCK = should make GB release bile
No stones present
*<35-40% removed you need to remove GB
Barium Swallow
MANY X-rays
All the way to duodenum
SEE : tumors, zinkers diverticulum, and anatomy
a lot of radiation
Zenker’s Diverticulum
Eat and feel like choke
Dysphagia usually in older pts
Food gets caught in throat becuz of outpouching
CT ABD and PELVIS with contrast
2 types of contrasts
ORAL : see intestines inside lumen, tumor, wall thickness, obstructions, perforations, appendix, diverticulitis
IV : see vascular relationships
high radiation
*CT scan sees exactly where obstruction is
CT ABD and Pelvis with no contrast
*kidney stones
Very intense pain
Use KUB or renal US for pregnancy
EGD
Upper Endoscopy
Upper GI to duodenum
*inflammation, ulcers, remove foreign bodies, bleeding
* YOU NEED CONSENT
Colonoscopy
Same as EGD just for the LI (colon)
Cystoscopy
Same as EGD just for the bladder, urethra
Risk for EGD
Perforation of viscera
When should I do EGD
GERD, UGIB, Dysphagia, odynophagia, place feeding tube, bleeding, ulcers
How do you prep for and then place EGD
No eating after midnight day before, no liquids for past 2hrs
Sedation of PT + intubation = protect airway
Prep for Colonoscopy and how to do it
Look for what
No eating after 4- hr before bed
Take laxatives and only fluids allowed
Light sedation
= colon cancer, rectal bleeding, surveillance
Cystoscopy when should I give this to someone
PAINLESS HEMATURIA
Kidney stones ,recurrent UTI, urinary obstruction
Quick and doesn’t always need sedation or prep
