Which term describes a lesion with uniform high density on radiographs?

• A. Totally hyperdense
• B. Totally hypodense
• C. Mixed (lytic-sclerotic)
• D. Amorphous bone

Answer: (A)

In radiographs, density describes how bright or dark a area appears: radiopaque (dense, white) versus radiolucent (less dense, dark). A lesion that is uniformly dense across its entire area is described as totally hyperdense, meaning it is radiopaque throughout with no dark (lucent) spots. This is the best description for a lesion with uniform high density.

Totally hypodense would mean the lesion is uniformly dark, which is the opposite of what’s asked. Mixed (lytic-sclerotic) indicates both low-density (lytic) and high-density (sclerotic) areas within the same lesion. Amorphous bone isn’t a density descriptor and doesn’t convey uniform radiodensity.
