Identify the five basic characteristics of an image that
determine its quality.
Describe generally how each characteristic affects
visibility of anatomical structures and signs of pathology.
While looking at a chest radiograph, explain the concept of
object and area contrast.
While looking at a chest radiograph, identify areas in which
object contrast appears to be reduced because the areas are either too light or
Explain the concept of contrast sensitivity and it's
significance in medical imaging.
Compare the contrast sensitivity characteristics of
radiography and MRI for visualization of soft tissue.
Identify the radiographic procedure that requires the
highest contrast sensitivity and explain why.
While looking at radiographs, identify some of the objects
that represent anatomical detail, estimate their sizes.
Describe the basic relationship between image blurring and
visibility of detail.
Compare and rank the various medical imaging modalities with
respect to blurring and visibility of detail. NOTE: In later
modules you will learn the factors in each imaging modality that have an effect
on blurring and visibility of detail.
Describe the appearance of image noise.
While looking at images from each modality identify the image
noise, Identify the modalities that appear to produce images with relatively low
noise, with relatively high noise.
Describe the effect of noise on visibility of objects within
an image and identify the object characteristic that makes it have reduced
visibility in the presence of noise. NOTE: In later modules you
will learn the factors in each imaging modality that produce and have an effect
on the noise.
Define and describe image artifact.
X Recognize common image artifacts in images from each
modality. NOTE: In later modules you will learn the factors in each
imaging modality that produce and have an effect on artifacts
Identify and describe three possible types of medical image
Identify and describe three major viewing condition factors
that have an effect on the visibility of objects within a medical image.
Describe the factors that produce optimum viewing conditions
for medical images.
Describe the special viewing conditions required in
mammography and explain how they are achieved.
Explain and compare the two characteristics of a diagnostic
procedure: sensitivity and specificity.
Define and briefly describe the clinical significance of:
True Positive, False Positive, True Negative, False Negative.
Sketch a receiver operating characteristic (ROC) curve, label
the scales, and describe factors that determine the position of the human
Interpret the general results of a receiver operating
characteristic (ROC) analysis.
Briefly describe the clinical application of ROC analysis.
