Evaluation of an Accelerated Body-whole Bone CT Procedure With the CZT "VERITON-CT ™" Camera

2019-11-14 17:39:54 | BioPortfolio


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)


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.

Medical and Biotech [MESH] Definitions

Irradiation of one half or both halves of the body in the treatment of disseminated cancer or widespread metastases. It is used to treat diffuse metastases in one session as opposed to multiple fields over an extended period. The more frequent treatment modalities are upper hemibody irradiation (UHBI) or lower hemibody irradiation (LHBI). Less common is mid-body irradiation (MBI). In the treatment of both halves of the body sequentially, hemibody irradiation permits radiotherapy of the whole body with larger doses of radiation than could be accomplished with WHOLE-BODY IRRADIATION. It is sometimes called "systemic" hemibody irradiation with reference to its use in widespread cancer or metastases. (P. Rubin et al. Cancer, Vol 55, p2210, 1985)

An irregular unpaired bone situated at the SKULL BASE and wedged between the frontal, temporal, and occipital bones (FRONTAL BONE; TEMPORAL BONE; OCCIPITAL BONE). Sphenoid bone consists of a median body and three pairs of processes resembling a bat with spread wings. The body is hollowed out in its inferior to form two large cavities (SPHENOID SINUS).

An acylated inactive complex of streptokinase and human lysine-plasminogen. After injection, the acyl group is slowly hydrolyzed, producing an activator that converts plasminogen to plasmin, thereby initiating fibrinolysis. Its half-life is about 90 minutes compared to 5 minutes for TPA; (TISSUE PLASMINOGEN ACTIVATOR); 16 minutes for UROKINASE-TYPE PLASMINOGEN ACTIVATOR and 23 minutes for STREPTOKINASE. If treatment is initiated within 3 hours of onset of symptoms for acute myocardial infarction, the drug preserves myocardial tissue and left ventricular function and increases coronary artery patency. Bleeding complications are similar to other thrombolytic agents.
