Initial experience of SPECT/CT in the diagnosis of occult scaphoid fracture.

Acta radiologica open

de Zwart AD, Beeres FJ, Rietbergen DD, Krijnen P, Schipper IB.
PMID: 26500783
Acta Radiol Open. 2015 Oct 08;4(10):2058460115602729. doi: 10.1177/2058460115602729. eCollection 2015 Oct.

BACKGROUND: *Equal contributors.Planar bone scintigraphy (PBS) is often advocated for diagnosing occult scaphoid fractures. PBS is a sensitive diagnostic modality, but lacks specificity, which may result in over-diagnosis.PURPOSE: To examine, in a pilot study, the potential additional value of...
