Pyuria is a common finding in renal disease and is defined
as the presence of:
(A) White cells in the urine
(B) Blood in the urine
(C) Casts in the urine
(D) Protein in the urine
(SPECT MPI) can evaluate regional wall motion and ven-
tricular volumes. Benefit of the combined assessment of
myocardial perfusion and function relate to all of the fol-
lowing EXCEPT:
(A) Help to differentiate attenuation artifacts from is-
chemia
(B) Aid to identify patients with multivessel coronary artery
disease
(C) Assist in diagnosing arrhythmias
(D) Provide prognostic value
Bilinear scaling methods employed in combined positron
emission tomography/computed tomography (PET/CT)
scanners software are used to:
(A) Convert CT image values to PET attenuation coefl-
cients
(B) Correct image misregistration
(C) Improve counting statistics of the PET acquisition
(D) Adjust positional mismatches
A patient referred for Meckel's diverticulum imaging re-
ceived Cimetidine orally every 6 h for 1 day before the
diagnostic imaging commenced. Cimetidine was given in
,A - White cells in the urine
Hematuria - blood in the urine, proteinuria - protein in
theurine, cylindruria - microscopic casts in the urine.
C - Assist in diagnosing arrhythmias
(A) Convert CT image values to PET attenuation coeflcients
A - To inhibit secretion of pertechnetate into the
bowel

radionuclide study to reduce radiation dose to the thyroid.
(C) To prevent pertechnetate accumulation in the thyroid
(D) To stop gastrointestinal bleeding

Acute radiation syndrome (ARS) is defined as an acute
illness caused by irradiation of the entire body (or most
of the body) by a high dose of radiation in a very short
period of time. What is the other requirement for the valid A - The radiation must be penetrating

(B) The dose must be internal
(C) Radiation injuries must involve hands
(D) Patient must recover in 6 months
For Food and Drug Administration (FDA) approved

A - 0.6-4 mm
range of positrons in human tissue is about:
In a PET camera of diameter 1 m and active transaxial
(A) 0.6-4 mm
FOV of 0.6 m the range of positron results in a positional
(B) 4-5 mm
inaccuracy of 2-3 mm.
