Clinical Trial Summary

The purpose of the OSS study is to evaluate a procedure involving a single full body TEMP / TDM 3D recording with a new semiconductor camera, the VERITON-CT ™ (Spectrum Dynamics Medical). This recording can be done in less than 25 minutes due to an original system of CZT (Cadmium-Zinc-Telluride) detectors allowing to increase the quality of the images and especially, to multiply by a factor 2 to 3 the detection sensitivity. This camera is also equipped with a scanner capable of obtaining a body-to-integer recording with a low level of irradiation (≤ 2 mSv)

Description:

Interventional study (RIPH-2), monocentric and randomized in open. All patients routinely referred for bone scans as part of a search for primary or metastatic neoplastic bone lesions (known neoplastic history) will be offered to participate in the study by the doctors of the nuclear medicine department of the CHRU from Nancy.

The capture of tracers used for bone scintigraphy (technetium-99m-labeled bisphosphonates) is highly dependent on bone remodeling, osteoblast activity and tissue perfusion . This is why bone scintigraphy is a sensitive examination, capable of detecting anomalies before their radiological translation . 3-dimensional (3D) recordings called SPECT detect bone metastases with a sensitivity equivalent to that of MRI .

These SPECT are most often produced by hybrid systems, in combination with X-ray scanner (CT) recordings, which makes it possible to correct certain imperfections in the quantification of the measured activities (attenuation, diffusion, partial volume) and also, to complete the characterization of lesions.

Bone diseases, which are often diffuse, frequently require two-dimensional (2D) whole body recordings, but these are unfortunately less informative and less sensitive than 3D recordings. This is why complementary focused SPECT / CT images are recommended for areas that are difficult to explore, especially the pelvis and spine, and when neoplastic lesions are suspected. This registration procedure is long (about 40 minutes), difficult for some patients to support, and does not offer an optimal 3D analysis of the entire skeleton.
