TEST: Optimization of PET

1. Indications for PET imaging include all of the following except ... ?

         Monitoring and staging cancer

        Post therapeutic evaluation

        Evaluation of pulmonary nodules

        Detection of deep vein thrombosis

2. An annihilation occurs when... ?

        Positron and electron masses are converted into two 511 KeV photons

        Neutron masses convert to pure energy

        Nuclei decay by electron capture

        Photons leave the nucleus

3.   The total PET count rate is a sum of ... ?

        Positrons, electrons, and neutrinos

        Positrons, electrons, and photons

        Trues, randoms, and scatter

        Trues, scatter, and positroniums

4. Randoms and Scatters... ?

        Add an inhomogeneous noise to a PET image

        Are independent of the size and density of the patient

        Account for 95% of the total counts

        Can not be corrected for with processing algorithms

5. Attenuation Correction creates a ... ?

        Collection of images from positrons

        Tissue density map to compensate for non-uniform densities in patient

        Reconstruction filter to apply to PET data

        Longer PET path to patient

6.   Fluorodeoxyglucose is a (an) ... ?

        511 KeV positron

        Contrast solution given to patients prior to scanning

        Metabolizable analogue of glucose

        Sugar analog labeled with fluorine-18

7. Radiolabeled Sugar Analogs...?

        Are retained longer in the body than normal sugars

        Have a decreased uptake in many tumors

        Are injected after the PET scan to increase sugar levels in patients

        Are labeled to the patient’s red blood cells

8. Patient Preparation for PET studies include... ?

        Keeping patients NPO for at least 4 hours post injection

        Asking patient to exercise before test

        Checking blood glucose level

        Obtaining written consent for scan after explaining study

9. Cardiac PET imaging with F-18 FDG requires... ?

        The patient’s glucose level to be above 180 mg/dl

        Patients to be NPO for one hour prior to injection of F-18 FDG

        Monitoring and possible adjustment of patient’s sugar or insulin levels

         An exercise treadmill test with injection of F-18 FDG at conclusion

10. Quality Control... ?

        Does not need to be performed for PET imaging

        Needs to be done once a month

        Emission and transmission images need to be analyzed daily

        Is done automatically through computer and camera software
