100% Correct Solutions
Z-Filtering - Answer The mathematical process that allows multidetector CT (MDCT)
images (thin sections) to be reconstructed at any point along the acquired volume is
commonly referred to as:
The gap between each slice - Answer What is Z-gap?
As Pitch increases, Z-gap decreases and Image Quality improves - Answer Correlation
between Pitch and Z-gap and Image Quality
A large pitch will reduce contrast resolution because the gap between slices is also
wider, which affects the data interpolation process for image reconstruction - Answer
How does Pitch affect Contrast Resolution? Why?
Constant mAs - Answer The product of milliamperage (mA) and scan time (seconds)
utilized for a CT acquisition.
Iterative Reconstruction - Answer Mathematical Reconstruction method a CT system
uses to decrease image noise and patient dose?
L1 - L2 (immediately inferior to the origin of the Superior Mesenteric Artery) - Answer At
what Vertebral Level(s) do the Renal Arteries arise?
Posterior - Answer Do Renal Arteries run Posterior or Anterior to Renal Veins?
Anterior - Answer Is Inferior Vena Cava Located Anterior or Posterior to Right Renal
Artery?
, L1 - Answer What Vertebral location does the Superior Mesenteric Artery arise from?
42 - 58 - Answer Blood
Average CT number range
CBF (Cerebral Bood Flow) - Answer During CT perfusion studies, the quantity of blood (in
mL) that moves through 100 g of tissue each minute is termed the:
50 to 60 mL per 100g of brain tissue per minute - Answer Normal CBF (Cerebral Blood
Flow) Range in Gray Matter
Gapped Image Data - Answer Slice Interval More Than Slice Thickness
Overlapped Image Data - Answer Slice Interval Less Than Slice Thickness
Binning - Answer The electronic combination of signals from adjacent detectors to form
a CT image
Hounsfield bar artifact - Answer Specific type of streaking beam-hardening artifact that
occurs in the posterior fossa of the brain
Linearity - Answer The relative accuracy between calculated CT numbers and their
respective linear attenuation coefficients
mGy - Answer Units CTDI is measured in
