NMTCB 2 Test Questions with Correct Answers Latest Update 2025 Graded A+
Before tracer administration, all of the following preparations are required for a 27 year old woman
referred for a total body bone imaging EXCEPT
A. Removing attenuating materials from the patient
B. Answering the patients questions
C. Ruling out Pregnancy
D. Explaining the procedure to the patient
E. Swab the injection site with alcohol - Answers A. Removing attenuating materials from the patient
It is not necessary to have the patient remove any attenuating materials until just before he or she is
imaged
Which of the following structures normally appear as areas of increased activity on the bone images of
children
A. diaphysis of the long bones
B. Breast tissue
C. Lumbar spine and cranium
D. Costochrondral junctions and Epiphyseal plates
E. Metatarsals - Answers D. Costochondral junctions and Epiphyseal plates
In children, normally increased tracer activity appears in areas of active bone growth. These areas
include the Epiphyseal plates at the ends of the long bones and the cosstochondral junctions in the ribs
If tracer concentration is visualized in the skeleton, stomach and thyroid and salivary glands on a bone
image, the most likely explanation for these findings is that
,A. Patient was imaged too soon after tracer administration
B. Patients renal function is compromised
C. Radiopharmaceutical contained excess free 99mTc Pertechnetate
D. Incorrect radiopharmaceutical was administered
E. Radiopharmaceutical contained excess free 18F Sodium - Answers C. Radiopharmaceutical contained
excess free 99mTc Pertechnetate
99mTc-labeled bone agents are prepared by combining medromite or oxidronate with 99mTc-
Pertechnetate. Typically about 3-10% of the Pertechnetate does not bind to the metronate or
oxidronate so there is always some unbound or "free" Pertechnetate in any bone tracer Preperation.
This percentage is so small compared with the amount of Tc99m-Medronate or oxidronate in the prep
and is not visualized on the bone image. If the radiopharmaceutical was not properly compounded or
the 99mTc-labeled detached from the chemical compound the excess 99mTc Pertechnetate taken up by
the thyroid, salivary glands and stomach is visualized on the bone image
For interpretation of nuclear medicine lung images, a chest x-ray is required to
A. Rule out possible causes of the patients symptoms
B. Determine cardiac size
C. Rule out previous lung surgery
D. Rule out PE
E. Rule in a PE - Answers A. Rule out possible causes of the patients symptoms
Many symptoms of PE are similar to that of rib fracture, MI, and pneumonia. Increases specificity of the
lung image findings for a physician
The image shown was obtained after the administration of 99mTc-MAA. Which of the following is the
most likely explanation for the quality of this lung perfusion image?
A. The image shows lung pathology
B. There is radioactive contamination on the patient's skin or the camera detector
,C. Blood clotted to MAA particles was injected intravenously
D. Too many MAA particles were administered to the patient
E. A left to right shunt occurred in the heart - Answers C. Blood clotted to MAA particles was injected
intravenously
Blood that is withdrawn into the syringe and allowed to mix with the 99mTc-MAA for a prolonged period
may cause the MAA particles to clump together and the blood to clot. If injected into patient can appear
as multiple small hot spots on image
The purpose of a charcoal filter in a xenon delivery unit is to absorb
A. Bacteria
B. Carbon dioxide
C. Xenon Gas
D. Moisture
E. Oxygen - Answers C. Xenon Gas
The NRC sets limits on airborne concentration of 133Xe. For this reason, 133Xe that the patient exhales
must be trapped for decay. Certain xenon delivery units use activated charcoal for trapping the xenon
Radionuclide venography may be performed with which of the following radiopharmaceuticals
A. 99mTc Pentetate
B. 99mTc Pertechnetate
C. 99mTc Exametazime
D. 99mTc Mebrofenin
E. 99mTc MAA - Answers E. 99mTc MAA
99mTc-MAA may be used or 99mTc-labeled red blood cells
, If 99mTc-MAA is used the lungs may be imaged after venogram to rule out PE
If ectopic thyroid tissue is suspected, the technologist can expect to find it most commonly in which of
the following areas?
A. In the brain
B. In the skull
C. In the nasopharynx
D. In the mediastinum
E. Behind the optic nerve - Answers D. In the mediastinum
Sublingual thyroid tissue occurs when the tissue does not descend from the base of the tongue to the
neck during fetal development. It is often associated with hypothyroidism. Mediastinal thyroid tissue is
often discovered after investigation of an anterior mediastinal mass visualized on chest-xray
During parathyroid imaging, images of the chest as well as the neck are obtained to
A. Correct the image series for patient motion
B. Visualize substernal thyroid tissue
C.Visualize ectopic parathyroid tissue
D.Diagnose hyperparathyroidism
E. To localize the parathyroid - Answers C.Visualize ectopic parathyroid tissue
The upper mediastinum between the heart and the thyroid is imaged to visualize ectopic tissue
When performing a gated equilibrium cardiac study, which of the following anatomical views best
separates the right and left ventricles
A. Left lateral
