LATEST 2025/2026 GUIDE
Static renal imaging - Correct Answer - 1. give 5 mCi Succimer
2. flow, then image 2-3 hrs post
3. LPO AND RPO images obtained as required
4. imaging may occur at 24 hr
Cystography - Correct Answer - 1. evaluation of vesicoureteral reflux.
DTPA OR MAG3 used for indirect method. Pertech or sulfur colloid used
for direct method.
INDIRECT METHOD
1. IV of MAG3 or DTPA
2. void while being imaged
reflux can be seen that way
DIRECT METHOD
1. catheterize patient to a bottle of saline with 1 mCi of Pertech
2. image supine.
3. dynamic images obtained of bladder being filled
4. discontinue infusion when bladder compacity is reached.
5. obtain prevoid image
6. obtain voiding images
7. obtain post void image
,Liver and Spleen imaging - Correct Answer - 1. 10 mCi Tc Sulfur colloid
engulfed by phagocytosis
2. Flow study if needed
3. otherwise image 10-15 post injection
4. static imaging ant/post, RAO, LAO, LPO, RPO.
5. marker image placed on right costal margin
6. SPECT may be performed.
distribution is 85%, 10%, and 5%
7. tumors, cysts, abscesses appear as decreased uptake.
the cystic duct and common hepatic duct join to form.... - Correct Answer
- common bile duct
Cholecystokinin (CCK) - Correct Answer - 1. Hormone secreted primarily
by the small intestine that promotes gallbladder contraction.
2. given 0.02 mcg/kg in 50 mL saline over 60 minutes infusion
HIDA scan - Correct Answer - 1. radioactive imaging of the liver,
gallbladder, and intestine.
2. use 5 mCi mebrofenin, disofenin, or lidofenin.
3. image immediately dynamically for 60 minutes.
Normal gallbladder EF is 35%
visualization of tracer in ducts is around 15-30 min
gallbladder visualized in 45-60 min
, Morphine Sulfate - Correct Answer - 1. causes contraction of sphincter of
oddi to increase pressure in bile ducts.
2. 0.04 mg/kg then image over 30 minutes. give boost dose after.
3. make sure they do not have a morphine allergy
RBC Liver Scan - Correct Answer - detection of liver hemangioma is
other benign tumor. no special prep needed
1. use 20-25 mCi RBCs (in vitro preferred)
2. optional flow
3. blood pool image optional
4. delayed imaging 45-180 min
hemangiomas have decreased perfusion on flow, but increased on
delayed image.
Meckel's diverticulum scan - Correct Answer - 1. NPO 2 hrs prior
2. give pentagastrin (6 ug/kg) or cimetidine (300 mg 4 times a day), or
glucagon. 15-20 min prior to radiopharm. this stimulates gastric
secretion, this will increase pertech secretion in stomach and
diverticulum.
3. position same as renogram.
4. dynamic images for 30-60 minutes.
should be visualized within 10-15 min. seen normally in right lower
quadrant.
