During CT arthrography, iodinated contrast media is injected directly
into the:
A. Intra-arterial space
B. Subarachnoid space
C. Intra-articular space
D. Intrathecal space - Correct Answer - Intra-articular space
When contrast is administered directly into a joint space, this is referred
to as an intra-articular injection
Which of the following connects the small intestine to the large
intestine?
A. Duodenal bulb
B. Pyloric sphincter
C. Ileocecal valve
D. Cecum - Correct Answer - Ileocecal valve
The ileum connects to the large intestine via the ileocecal valve.
At which vertebral level does the spinal cord end?
A. L5-S1
pg. 1
,B. L3-L4
C. L1-L2
D. T11-T12 - Correct Answer - L1-L2
The spinal cord begins at the medulla of the brain and ends at
approximately the L1 vertebra.
Which of the following is most likely to require images of less than 1
mm in thickness?
A. CT Cardiac Calcium Score
B. CT Chest High Resolution
C. CT Chest
D. CT Lung Nodule - Correct Answer - CT Chest High Resolution
CT Chest High Resolution often requires images of less than 1 mm in
thickness, as well as images with 10-15 mm in thickness.
Image acquisition in a CT Pancreas exam typically occurs after which of
the following?
A. 10-20 seconds
B. 35-45 seconds
C. 50-65 seconds
D. 70-90 seconds - Correct Answer - 35-45 seconds
When performing a CT Pancreas exam, imaging is often acquired during
a delayed arterial phase (35-45 seconds) when the parenchyma of the
pancreas is at peak enhancement.

,The ability of a CT scanner to distinguish two objects that are close
together with different densities is known as:
A. Contrast resolution
B. Linearity
C. Temporal resolution
D. Spatial resolution - Correct Answer - Spatial resolution
It is the ability of the CT scanner to show small objects that are close
together and to distinguish structures with different densities.
Which of the following describes the artifact that arises as the beam
becomes harder in the center of an image than it does at the edge
A. Cone beam
B. Cupping
C. Streaking
D. Beam hardening - Correct Answer - Cupping
Cupping artifacts arise in an image when the beam becomes harder in
the center of the object being imaged, than it does at the edge. This
artifact commonly occurs in the CT Head exam.
When there are not enough photons that strike the detector and the
resulting image is noisy, this is known as:
A. Uniformity
B. Quantum mottle
C. Noise
D. Photon flux - Correct Answer - Quantum mottle
pg. 3
, It is the result of an x-ray photon flux. When there are not enough
photons that strike the detector, it results in an image that appears noisy
when reconstructed.
Increasing radiation dose to overcome the penumbra at the edge of the
detectors is known as:
A. Interpolation
B. Cone beam
C. Overbeaming
D. Overranging - Correct Answer - Overbeaming
Overbeaming occurs to overcome the penumbra that occurs at the edge
of the detectors. Overbeaming results in increased radiation dose to the
patient.
Multi-segment reconstruction has a direct impact on which of the
following?
A. Spatial resolution
B. Temporal resolution
C. Noise
D. Contrast resolution - Correct Answer - Temporal resolution
The use of half-scan or multi-segment reconstruction both directly
impact the temporal resolution of a CT scanner.
A typical CT number for bone is:
A. +3000 HU
B. -1000 HU
