What imaging modality offers excellent spatial resolution and is not limited by tissue superimposition for skeletal disease?

• A. MRI
• B. Nuclear scintigraphy
• C. CT
• D. Ultrasound

Answer: (C)

Cross-sectional imaging that removes tissue overlap is ideal for precise bone assessment. CT provides thin-slice, high-resolution cross-sectional images with isotropic voxels, allowing clear visualization of cortical bone, small fractures, joint surfaces, and subtle osseous changes. The ability to reconstruct in multiple planes and render 3D views helps localize lesions accurately and evaluate complex skeletal anatomy without the confusion of overlapping structures seen on 2D radiographs. While MRI excels at bone marrow and soft-tissue detail, and nuclear scintigraphy or ultrasound have other strengths, CT offers the best spatial resolution for bone and is not limited by tissue superimposition, making it the superior choice for skeletal disease.
