a tech receives a request for a patient to receive Sm153 for palliation of
pain from bone mets. the patient has a WBC count of 3500 and 40000
platelets. what should happen next?
a. the order should be changed to Sr89
b. the tx should be delayed until the platelet ct is at least 60,000
c. the tx should be delayed until the WBC is below 2400
d. the Sm153 should be ordered - ACCURATE ANSWERS✔✔ B. the tx
should be delayed until the platelet ct is at least 60,000
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 - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ 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 Immediately, a 20 mCi dose is withdrawn for a bone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withdrawn meanwhile, and the decay factor for 1.5 hrs is 0.841)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 - ACCURATE ANSWERS✔✔ 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 - ACCURATE ANSWERS✔✔ 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
- ACCURATE ANSWERS✔✔ d. collecting the patient's waste and
storing until decayed to background
bone marrow imaging is performed using:
a. MDP
b. HDP
c. sulfur colloid
d. Gd153
e. A and B - ACCURATE ANSWERS✔✔ C. sulfur colloid
why would an image of the brain be obtained during a lung perfusion
scan using Tc99m MAA?
a. rule out brain mets
b. to detect low tagging efficiency
c. to detect a R-L cardiac shunt
d. to see if pulmonary emboli have traveled into the cerebral arteries -
ACCURATE ANSWERS✔✔ c. to detect a R-L cardiac shunt
