Which imaging modality is not commonly used in cerebral palsy evaluation?

• A. PET scan
• B. MRI
• C. CT scan
• D. Traditional X-ray

Answer: (A)

In cerebral palsy evaluation, imaging is mainly about anatomy—where and how the brain was injured and what structural patterns are present—because that information guides understanding of the condition and potential management. MRI is the go-to because it gives detailed brain images with excellent soft-tissue contrast and no radiation. CT is used when MRI isn’t available or feasible, or for quick assessment in acute situations, since it also reveals brain structure well enough for many clinical decisions. Traditional X-ray isn’t brain imaging, but it serves to evaluate musculoskeletal issues CP patients often face, like scoliosis or joint alignments, which influence therapy. A PET scan looks at metabolic activity rather than anatomy. For cerebral palsy, this metabolic information rarely changes practical management or prognosis, and PET is more costly, less accessible, and requires handling radioactive tracers and specialized interpretation. Because of these factors, PET is not routinely used in CP evaluation.
