Diagnostic value of single-photon emission computed tomography-CT foot and ankle studies

Abstract

Aim: The aim of this study is to determine the impact of foot and ankle single-photon emission computed tomography (SPECT) CT on patient management.

Method and materials: A retrospective review over a 7-year period investigating whether the study identified or confirmed a source of symptoms. The electronic patient record was reviewed to see whether the test was helpful to the onward management of the patient.

Results: In total 44 patients were included and pathology was identified in 40 of the 44 patients, with four having normal studies. SPECT CT was deemed helpful in the management of 39 of the patients with the positive usefulness overall calculated as 89%. The remaining five patients where the test was not helpful have been discussed.

Conclusion: SPECT-CT is a helpful imaging test in the diagnosis of foot and ankle disorders with 89% of studies being diagnostically useful.
