Principles of interpretive Radiology Flashcards
Interpretation concepts
Know the pt info
Interpret only good quality images
consider geometric factors
Evaluate lesion in all dimensions
Assess location, size and shape of lesion
Recognize patterns of bone change
Understand the meaning of patterns
Order advanced imaging as needed
Lesions that are found above the mandibular canal are most likely of __ origin
Odontogenic
(may derive from tooth forming elements of the jaw)
Lesions that are found within the mandibular canal are of __ origin
vascular or neural
Lesions that are found inferior to the canal are
non-odontogenic
(May arise from epithelial remnants of embryonic ducts lest behind after embryonal facial and jaw development)
If the lesion is in the canal is can look __ shaped
football
IF the lesion covers the canal how can we tell where the lesion originates from
If the canal is out of position (pushed up or down) it can tell us where the lesion started based off the way it moved
Signs of infection and malignancy
Ill defined
Teeth are left alone just without any support
An imaging description formula helps you to obtain a
Differential Diagnosis
The determination of which of two or more disease with similar symptoms is the one from which the patient is suffering, by a systematic comparison and contrasting of the clinical findings
Differential Diagnosis
What are the 7 things involved in the differential diagnosis
Number
shape - internal structure
size
periphery
density
location
effect on surrounding structure
What sizes can we call a lesions
Small or large
(measure approximately - use common sense)
What are the 5 shapes of lesions
Round
Ovoid
Irregular
Scalloped
Triangular (TMJ)
Internal structure of lesion can be
Unilocular
Multilocular
