A diphosphonate kit contian 180 mCi of Tc99m in 30 ml when it is prepared at
8am. Immediately, a 20 mCi dose is withdrawn for a bone scan. if the patient
arrives late at 9:30 and half the volume is accidentally discharged, how much
volume from the kit must now be added to the syringe to correct the dose to 20
mCi? (no other doses have been withdrawn meanwhile, and the decay factor for
1.5 hrs is 0.841)
a. 1.5 ml
b. 2.0 ml
c. 2.3 ml
d. 2.5 ml
e. 2.7 ml - CORRECT ANSWER-C. 2.3 mL
lots of math, sorry :(
a WBS bone scan film shows a good posterior image, but the anterior view
appears diffuse with greater soft tissue activity. what is the probable cause?
a. wrong collimator used for anterior
b. increased patient to detector distance on the ant relative to the post
c. low tagging efficiency of the RP
d. patient was not sufficiently hydrated
e. none of the above - CORRECT ANSWER-b. increased patient to detector
distance on the ant relative to the post
,Which of the following will not reduce the probability of contamination from
perspiration and saliva of a therapy patient?

, all of the following have an effect on the concentration of eluate obtained from a
wet generator except:

port
