Session One Flashcards
Describe what Radio dense/Radiopaque is?
Light/white area on the radiograph due to presence of dense objects in paths of photons that are strong absorbers e.g., metal replacement
Describe what Radiolucent is?
dark/black area on the radiograph due to maximum number of photons passing through the object e.g., air
What is contrast?
The degree of difference between adjacent densities
What is Density?
Radiographic density is dependent on amount of radiation received and refers to the degree of darkening of an exposed radiograph e.g.,
- white areas = no density
- black areas = maximum density
What condition could have Uniform joint space loss?

What condition could have Non - Uniform joint space loss?
Osteoarthritis
