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:

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

The gamma-camera is the most widely used imaging piece of equipment in nuclear medicine. The performance parameters of a routine gamma-camera quality control (QC) program include all of the following EXCEPT:

Well Counter (WC) and Uptake Probe (UP) are two detectors commonly configured to a single computer. Which of the following statements describing their properties is INCORRECT?

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?

All of the following single photon emission computed tomography (SPECT) quality control procedures can be performed by the technologist EXCEPT:

To ensure the proper operation of the dose calibrator, all of the following quality control procedures must be performed on the unit EXCEPT:

All of the following quality control (QC) tests are performed in nuclear medicine department to assess the reproducibility of radiation counter EXCEPT:
