Quality Control

Every received package holding radioisotopes must be logged in properly. The incoming package logbook must include all of the following data EXCEPT:

The extrinsic flood image evaluates the uniformity of:

The blank scan is performed daily on Positron Emission Tomography (PET) scanners using a Ge-68 transmission source. The term blank scan reflects:

When tested Tc-99m sulfur colloid kit with TLC for free Tc-99m, the technologist noted: strip with free Tc-99m migrated to the solvent front reads 650 cpm, and strip containing Tc-99m sulfur colloid remaining at the point of origin reads 18350 cpm. What is the radiopharmaceutical impurity of this sulfur colloid kit?

The dose calibrator’s ability to measure accurately a range of low-activity doses to high-activity doses is called:

Increasing the thickness of the scintillation detector will result in the detector:

If expected value of the long-lived source is 120 mCi and actual reading obtained from dose calibrator is 122 mCi, what is the percentage error of that reading?

The battery check, sealed source check, and calibration are three different quality control procedures performed to ensure proper operation of the:

Spatial resolution and spatial linearity of a gamma-camera is assessed with a 4-quadrant bar phantom which consists of four sectors of lead bars and intervening plastic strips:

Co-57, Ge-68, and Ba-133 are sometimes called “mock” isotopes. Which of the following trios of isotopes do they imitate?
