Week 6 - Radiogrpahic Terminology Flashcards
Calcification
Denotes the deposition of calcium in a tissue without exhibiting cortical or trabecular patterns
Contrast
Difference in degree of density or shape distinction between black and white images
Decreased density
A blacker or darker shadow on the X-ray film
Density
The amount of blackening in the radiographic image
Dysplasia
An intrinsic disturbance in the growth of bone
Dystrophy
An extrinsic disturbance of the nutrition or metabolism of bone
Eburnation
The final end product of bone sclerosis
Increased density
A whiter or lighter shadow on the X-ray film
Lipping
Small osteophytic formation on the margin of the articular surface of bone (should,not be confused for bone spurs)
Ossification
Organised deposition of calcium which exhibits cortical and trabecular patterns
Osteoporosis
A condition which demonstrates a decrease in density, usually exhibited by a decrease in the number of ossified trabecular
Radiolucency
Denotes greater penetrability by the X-rays and has the same connotation as decreased density
Radiopacity
Denotes diminished penetrability by the X-ray and has the same connotation as increased density
Resorption
Refers to the loss of bony substance which is usually manifested in the periosteal (outer covering), endosteum (inner covering) and the ends of the affected bone
Sclerosis
An increase in the density of bone such that it’s radiographic appearance is much whiter than usual
