Bone Lesion Clinical Trial
Official title:
Contribution of MUltiparametric Analysis in Bone Scintigraphy for the Characterisation of Solitary Bone Lesions Whose Malignant Origin Cannot be Excluded on Conventional Imaging
The hypothesis of the study is that non-invasive Single photon emission computed tomography (SPECT-CT) bone scintigraphy makes it possible to better characterize solitary bone lesions, in particular the exclusion of their malignancy in order to avoid unnecessary biopsy and possible complications for the patient.
Bone scintigraphy includes 3 stages: study of perfusion then of early tissue uptake and finally of late bone fixation. Hyperactivity of malignant bone lesions at the 3 stages of bone scintigraphy has been reported, but on planar scintigraphic images not allowing precise anatomical localization of the lesions. Currently, the generalization of SPECT-CT (Single Photon Emission Computed Tomography) combined with Tomodensitometry) acquisition thanks to the deployment of semiconductor cameras, makes it possible to carry out a multiparametric analysis of bone lesions with quantification of the intensity of the signal expressed in SUVmax (Standard Uptake Value maximum) at the 3 times of the scintigraphy ;
