a

True

b

False

2

Y-90 labeled glass microspheres is being used; the formula for dose calculation is; Activ required in GBq=(liver mass in Kg/ Desired dose in Gys)/50.

a

True

b

False

3

Tilmanocept is DTPA-mannosyl-dextran, a macromolecule with an average diameter of between 100 and 220 nm

a

True

b

False

4

Tilmanocept may be administered to a patient as a single injection or as multiple injections.

a

True

b

False

5

Smaller particles are generally recommended in lymphoscintigraphy as more frequent visualization of lymphatic channels is activated.

a

True

b

False

6

With lymphoscintigraphy for melanoma, imaging begins immediately after injection and is repeated at 5 minute intervals for 45 to 60 minutes.

a

True

b

False

7

Usual dose for Ga-67 Citrate is 5-10 mCi.

a

True

b

False

8

With Ga-67 Citrate, the reason for delayed views is concentration in tissue is stable while blood clearance improves over time.

a

True

b

False

9

With In-111 Oxine labeled WBCs, early lung activity occurs, then clears out.

a

True

b

False

10

With In-111 Oxine labeled WBCs, uptake in liver and spleen is abnormal.

a

True

b

False

11

Leukocyte agents are nonspecific and also localize in areas of inflammation, without infection.

a

True

b

False

12

Sestamibi Breast imaging should be delayed 2 weeks following FNA and 4-6 weeks post core biopsy.

a

True

b

False

13

The main disadvantage with Tc99m HMPAO WBC imaging is the tag to WBCs begins to breakdown leading to renal and GI excretion-this complicates GI infection localization.

a

True

b

False

14

Use of Y-90 labeled Glass Microspheres is contradicted in patients whose Tc99m MAA hepatic arterial perfusion scintigraphy shows any deposition to the GI tract that may not be corrected by angiographic techniques.

a

True

b

False

15

A tech cannot find a vein on a In-111 WBC patient; he can try using a 25g needle with no effect on scan.

a

True

b

False

16

Both benign and malignant conditions can result in lung nodules.

a

True

b

False

17

Patient should have no strenuous activity for 24 hours before PET/FDG scan.

a

True

b

False

18

Ideal patient blood glucose is 200mg/dl before FDG scan?

a

True

b

False

19

The most common adult FDG dose is 10 mCi.

a

True

b

False

20

ROCM enhancement occurs because it lets more photons through.

a

True

b

False

21

Total body PET FDG scanning is ideal for malignant melanoma and sarcoma patients.

a

True

b

False

22

In PET/CT, acquiring images with patients arms to the side would increase beam hardening and truncate CT data.

a

True

b

False

23

Gliomas are the most common brain tumors.

a

True

b

False

24

PET FDG is better than bone scans for prostate cancer mets.

a

True

b

False

25

Obese patients have lower SUVs for both normal and malignant tissue.

a

True

b

False

26

Due to partial volume effects , SUV of lesions smaller than the spatial resolution of the scanner will be overestimated.

a

True

b

False

27

I-125 seeds are indicated for permanent interstitial treatment of selected localized tumors such as ;head and neck, lung, pancreas, and early stage prostate.

a

True

b

False

28

Fluciclovine F-18 uptake is not specific for prostate cancer and may occur with other types of cancer and benign prostatic hypertrophy in primary prostate cancer.

a

True

b

False

29

Before initiating Lu-177 Dotatate; Discontinue long-acting somatostatin analogs (E.g. long-acting octreotide) for at least 4 weeks prior to initiating therapy. Administer short-acting octreotide as needed; discontinue at least 24 hours prior to initiating therapy.

a

True

b

False

30

Secondary brain tumors are more prevalent in the pediatric population while adults are more prone to experience primary brain tumors.

a

True
