**Core Concept**
Brighton's criteria is a set of guidelines used for the diagnosis of osteoporosis, specifically for the assessment of vertebral fractures on spinal radiographs. This criteria helps in identifying patients with osteoporotic vertebral fractures, which are a common complication of osteoporosis.

**Why the Correct Answer is Right**
Brighton's criteria takes into account various parameters such as the number of vertebral fractures, the morphology of the fractures, and the presence of other spinal abnormalities. The criteria categorize vertebral fractures into three types: minor, moderate, and severe. The minor fractures are those that do not significantly alter the vertebral body's height, moderate fractures have a height loss of 20-39%, and severe fractures have a height loss of more than 40%. This classification helps in distinguishing between osteoporotic fractures and traumatic fractures.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because Brighton's criteria is specifically designed for the diagnosis of osteoporotic vertebral fractures, not for other types of fractures.
**Option B:** This option is incorrect because the Genant's semiquantitative scoring system is another method used for the assessment of vertebral fractures, but it is not the same as Brighton's criteria.
**Option C:** This option is incorrect because the ASBMR criteria are used for the diagnosis of osteoporosis in general, but not specifically for the assessment of vertebral fractures.

**Clinical Pearl / High-Yield Fact**
When interpreting spinal radiographs, it is essential to look for vertebral fractures, especially in patients with a history of osteoporosis. Brighton's criteria can help in identifying patients with osteoporotic vertebral fractures, which can guide treatment decisions.

**Correct Answer:** C.
