NMTCB Practice Exam V2
1. Figure 4.2 presents the images obtained during 2 h hepatobiliary scintig- raphy after
intravenous injection of 6.0 mCi of Tc-99m Choletec. Which of the following statements is
most consistent with the findings from the scan?
(A) Normal hepatobiliary scan
(B) Sphincter of Oddi obstruction
(C) Cystic duct obstruction
(D) Liver cirrhosis: C - Cystic duct obstruction
Acute cholecystitis is the most common clinical indication for hepatobiliary scintig-raphy and
the usual cause of acute cholecystitis is obstruction of the cystic duct.
2. Radon is responsible for the majority of the mean public exposure to ionizing radiation
and it is often the single largest contributor to an individ- ual's background radiation dose.
Which of the following statements regardingradon and radon exposure is FALSE?
(A) It varies from location to location
(B) Radon is formed as part of the normal radioactive decay chain of uranium
(C) Radon is the most frequent cause of lung cancer
(D) Radon test kits are commercially available: C - Radon is the most frequentcause of lung
cancer
The most common cause of lung cancer is tobacco smoke.
3. An electron, stripped from an atom as a charged particle, passes throughmatter that has
enough kinetic energy to cause subsequent ionization at a distant site is called:
(A) Compton electron
(B) X-ray
(C) Delta ray
(D) Gamma ray: C - Delta ray
The charged particle giving rise to delta rays generally is relatively large, such asan alpha
particle but may also be a high-speed electron.
,4. Which of the following is an example of a "rigid" body organ?
(A) Heart
(B) Liver
(C) Brain
(D) Lung: C - Brain
The brain is considered a rigid organ since the shape and size of the brain stay fixedbecause of
the bony skull surrounding it.
5. How many dpm (disintegrations per minute) are produced by source that is reading 4,850
cpm (counts per minute) in well counter? Well-counter efficiency is 56% and background counts
are 150 cpm.
(A) 4,149 dpm
(B) 6,208 dpm
(C) 7,632 dpm
(D) 8,393 dpm: D - 8,393 dpm
(Appendix A, Formula 15)
6. Ga-67 citrate accumulates as an iron analogue through binding to circu- lating transferrin
and 10-25% of the radionuclide is excreted via the kidneys during the first 24 h. After 24 h the
principal route of excretion is:
(A) Saliva
(B) Sweat
(C) Hepatobiliary
(D) Skin: C - Hepatobiliary
During the first 24 h 10-25% of radionuclide is excreted by the kidneys.
7. The results of the study, known as INTERSTROKE, identified nine modifi-able risk
factors for stroke and accounting for 90% of disease. According tothe study the strongest risk
factor for stroke was:
, (A) Alcohol intake
(B) Hypertension
(C) Cigarette smoking
(D) Obesity: (B) Hypertension
8. Sentinel lymph node biopsy is a multidisciplinary technique in which nuclear medicine
performs preoperative lymphoscintigraphy. Which methodis utilized by surgeons to identify
the sentinel node?
(A) Gamma probe and/or blue dye
(B) Gamma-camera and/or blue dye
(C) Gamma probe and/or red dye
(D) Gamma-camera and/or red dye: A - Gamma probe and/or blue dye The surgeon
identifies and removes the LNs and the pathologist determines whetherthe metastases are
present.
9. Pyuria is a common finding in renal disease and is defined as the presenceof:
(A) White cells in the urine
(B) Blood in the urine
(C) Casts in the urine
(D) Protein in the urine: A - White cells in the urine
Hematuria - blood in the urine, proteinuria - protein in the urine, cylindruria - microscopic
casts in the urine.
10. (SPECT MPI) can evaluate regional wall motion and ventricular volumes. Benefit of the
combined assessment of myocardial perfusion and function relate to all of the following
EXCEPT:
(A) Help to differentiate attenuation artifacts from ischemia
(B) Aid to identify patients with multivessel coronary artery disease
(C) Assist in diagnosing arrhythmias
(D) Provide prognostic value: C - Assist in diagnosing arrhythmias
11. Bilinear scaling methods employed in combined positron emission tomog-
