In T2-weighted MRI, how does medullary bone appear?

• A. Dark
• B. Light
• C. Bright
• D. Gray

Answer: (A)

In T2-weighted MRI, medullary bone appears dark. This is due to the inherent properties of T2-weighting, where fluids present in the body tend to appear brighter due to their high water content. Conversely, structures like medullary bone, which have a lower water content, show a darker signal. This contrast between different tissues is essential for imaging and can help differentiate between various pathological conditions. In the context of podiatric medicine, recognizing the appearance of medullary bone on T2-weighted MRI can aid in diagnosing conditions like osteomyelitis or stress fractures, where the surrounding tissues and bone marrow would have abnormal MRI characteristics.
