Contribution of MUltiparametric Analysis in Bone Scintigraphy for the Characterisation of Solitary Bone Lesions

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

Overview

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.

Detailed description

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

Interventions

• Other Bone scan
  the bone scintigraphy will include 3 stages: study of perfusion then early tissue uptake and finally late bone fixation

Primary outcome measures

• Assess the diagnostic performance of the Time To Peak parameter [Time frame: 24 hours]

Secondary outcome measures (3)

• To evaluate the diagnostic performance of the Standard Uptake Value max at the early stage (2nd stage) in bone scintigraphy in the evaluation of the benign nature of indeterminate solitary bone lesions on conventional imaging. [Time frame: 24 hours]
• o evaluate the diagnostic performance of the Standard Uptake Value max at the early stage (3 rd stage) in bone scintigraphy in the evaluation of the benign nature of indeterminate solitary bone lesions on conventional imaging. [Time frame: 24 hours]
• Evaluate the impact of multiparametric analysis (combination of Time-To-Peak, Standard Uptake Value max early and late) in the classification of solitary bone lesions in bone scintigraphy. [Time frame: 24 hours]
