Radiology · Paediatric imaging: craniosynostosis

Sample item

An infant has a long, narrow skull with a palpable ridge along the sagittal suture. Which imaging best defines the fused sutures and plans surgery?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Low-dose CT with three-dimensional reconstruction

Premature sagittal suture fusion gives a scaphocephalic head. CT with 3D reconstruction shows which sutures are fused and assists surgical planning. Dose is kept low in infants, and MRI is used to assess associated brain anomalies.

Option by option

  • A. Isotope bone scan

    A bone scan does not image sutures well.

  • B. Low-dose CT with three-dimensional reconstruction (correct)

    Correct. 3D CT delineates the sutures.

  • C. Plain abdominal film

    An abdominal film is unrelated.

  • D. Fluoroscopy

    Fluoroscopy has no role.
