Résumé
Objective. - The purpose of our study was to evaluate the diagnostic performance of SPECT coupled to computed axial tomography (SPECT-CT) in our daily practice of bone scintigraphy. Subjects and methods. - SPECT-CT obtained as a complement to the planar bone scintigraphy in 39 patients were studied. Each type of image was retrospectively read by two differents observers: a nuclear medicine physician who was unaware of SPECT-CT results analysed planar bone scintigraphy, a second one who was unaware of planar bone scintigraphy results analysed SPECT-CT images. In this population of patients, 17 patients were addressed in an oncologic setting. The 22 other patients were addressed for pain of indeterminate origin without neoplasic context. Results. - In 13% of the cases, SPECT-CT specified the precise location of increased uptake foci seen on planar bone scintigraphy. In 38% of cases, SPECT-CT confirmed a diagnosis suspected by the planar bone scintigraphy. In 10% of cases, SPECT-CT established a diagnosis that was uncertain with planar bone scintigraphy. In 26% or cases, SPECT-CT brought no additional information. Finally in 3% of cases, SPECT-CT proved to be more sensitive than planar images. Conclusion. - Our study demonstrates the utility of SPECT-CT in the daily practice of bone scintigraphy, this complementary imaging study benefited to 74% of our patients.
