16 detector multislice CT versus skeletal scintigraphy in the diagnosis of wrist fractures: value of quantification of ⁹⁹Tc^m-MDP uptake

Departments of ¹ Radiology and ² Nuclear Medicine, Addenbrooke's Hospital NHS Trust and the University of Cambridge, Hills Road, Cambridge CB2 2QQ, UK

View larger version (72K): [in a new window]   Figure 1. A concordant fracture. (a) The local view bone scintigram planar image of the wrist shows focal increased MDP uptake in the region of the right trapezium. (b) On 16 detector CT the fracture was best identified (arrow) in the coronal plane.

(a) The local view bone scintigram planar image of the wrist shows focal increased MDP uptake in the region of the left trapezium. No fracture was identified on the 16 detected CT examined fully in all planes. (b) The trapezium is shown (arrow) on the coronal reconstructed CT image.
