,a SC kit requires the addition of 1-3 ml containing no more than 500mCi of TcO4-.
in addition, 1.5 ml of solution A must be added before boiling, and 1.5 ml of
Solution B must be added after cooling. If the kit is 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
max. 1 ml TcO4- containing 500 mCi
500/(1.5+1.5+1) = 125 mCi/ml
A hine-duley phantom is useful for testing the spatial resolution and spatial
linearity with only one image.
a. true
b. false - Correct answer-B. false
the advantage of a lung ventilation scan performed with Xenon is
a. the ability to match perfusion and vent positioning

,b. the ability to detect delayed washout
c. the ability to perform the exam at the patient's bedside
d. the ability to perform perfusion before ventilation without increasing the dose
given for the vent study - Correct answer-B. the ability to detect delayed washout
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 Immediately, a 20 mCi dose is withdrawn for a bone scan.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 (no other doses have been withdrawn meanwhile, and the decay factor for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?
a. disposable eating utensils
b. plastic covering over the mattress
c. covering the phone receiver with plastic
d. collecting the patient's waste and storing until decayed to background - Correct
answer-d. collecting the patient's waste and storing until decayed to background
