[Diagnostic imaging of osteoporosis: special reference to diagnosis by radiography and DXA].
Primary osteoporosis is diagnosed by diagnostic criteria, eg. whether non-traumatic vertebral body is or not, or the severity of low bone mass. As a diagnostic imaging of osteoporosis, grading of radiographic osteopenia, and Singh index in the upper end of femur are well-known. Vertebral fracture associated with osteoporosis shows wedge, fish or flat deformity, but it is necessary to differentiate from Schmorl node and so on. DXA is a main stream of bone mineral quantification method, and its image is expressed the distribution of bone mineral density per unit area.
