EACVI CARDIAC COMPUTED TOMOGRAPHY
EXAM 2026 EXAMINATION TEST FULLY
SOLVED QUESTIONS 100% CORRECT
◉ What is the limitation of CAC quantitation? Answer: is the
inability to measure and characterize non-calcified atherosclerotic
plaque
◉ MDCT for CAC quantitation typically employs which gating
approach for data acquisition Answer: Prospective gating
- With simultaneous ECG monitoring, scanning occurs only during
diastole (When the heart demonstrates the least motion)
-A user defined percentage of the R-R interval is set as the trigger for
data acquisition to occur during the T wave of the ECG
◉ Does prospective gating increase or decrease patient dose
Answer: Reduces patient dose and scan variability
◉ What is the Agaston scoring system Answer: it quantifies the
volume and density of calcium within the coronary arteries
, - Areas of calcium are identified as those greater than 1 mm squared
in the area with HU values above 130
◉ The Agaston scores are characterized and compared on the basis
of a patient's what Answer: age and sex
◉ Agaston CAC scores can be graded as Answer: 1-10: minimal
11-100: mild
101-400: moderate
>400: extensive
◉ How are MDCT for CAC quantitation exams performed Answer: -
as a low dose cine-axial exam
- contiguous 2.5 to 3.0 mm axial sections are sequentially acquired
from the aortic arch through the cardiac bases
◉ What is the importance of prospectively gated scans obtained in a
cine mode during diastole scanned with fast gantry revolution times
(0.35 seconds) Answer: to maintain excellent temporal resolution
and provide motion-free images
◉ what is the noninvasive evaluation of the arterial blood supply to
the heart known as Answer: Coronary CTA (CCTA)
