,correctly prepared, what is the max concentration of
Tc99m it could contain?
a. 83 mCi/ml
b. 125 mCi/ml
c. 167 mCi/ml
d. 500 mCi/ml - (correct answer) B. 125 mCi/ml

b. false - (correct answer) B. false
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is withdrawn for a bone scan.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have been withdrawn meanwhile, and the decay factor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 :(

relative to the post
c. low tagging efficiency of the RP
d. patient was not sufficiently hydrated
