Radiopharmaceuticals should be used only by physicians who are qualified by training and experience in the safe use and handling of radionuclides and whose experience and training have been approved by the appropriate government agency authorized to license the use of radionuclides. Xenon Xe-133, as well as other radioactive drugs, must be handled with care and appropriate safety measures should be used to minimize radiation exposure to patients and to clinical personnel. The vial stopper contains dry natural rubber latex and may cause allergic reactions in providers or patients who are sensitive to latex. The unrecognized loss of radioactivity from the dose for administration may render the study non-diagnostic. Xenon Xe-133 adheres to some plastics and rubber and should not be allowed in tubing or respirator containers. Xenon Xe-133 Gas delivery systems, i.e., respirators or spirometers, and associated tubing assemblies must be leak-proof to avoid loss of radioactivity into environs not specifically protected by exhaust systems. CONTRAINDICATIONSĪdverse reactions related to the use of this agent have not been reported to date. It may also be applied to assessment of cerebral flow.

Our technique can be expanded to diagnose "benign" pleural adhesions for safer thoracoscopic surgery.Ĭomputer-assisted image analysis Four-dimensional computed tomography Lung cancer.Inhalation of Xenon Xe-133 Gas has proved valuable for the evaluation of pulmonary function and for imaging the lungs. Find company research, competitor information, contact details & financial data for SOCOTEC DIAGNOSTIC of CENON, NOUVELLE AQUITAINE.A unique color map clearly demonstrates parietal pleural invasion/adhesion.4D dynamic-ventilation CT can correctly assess parietal pleural invasion/adhesion of peripheral lung cancer.Software-assisted 4D dynamic-ventilation CT can be considered as a novel imaging approach for accurate preoperative analysis of pleural invasion/adhesion of peripheral lung cancer. Software-assisted 4D dynamic-ventilation CT images achieved perfect diagnostic accuracy for pleural invasion/adhesion (sensitivity, 100% specificity, 100% area under the curve, 1.000) compared to conventional chest CT (sensitivity, 60% specificity, 77% AUC, 0.846). Parameters of diagnostic accuracy were assessed, including a receiver operating characteristic analysis.

Two chest radiologists, who were blinded to patient status, cooperatively evaluated the presence of pleural invasion/adhesion using two different imaging modalities: (i) conventional high-resolution CT images, reconstructed in the axial, coronal, and sagittal directions, and (ii) 4D dynamic-ventilation CT images combined with a color map created by image analysis software to visualize movement differences between the lung surface and chest wall. An induction should be mixed well together. The purpose of this article is to review the techniques, clinically relevant potential applications, and limitations of xenon-enhanced dual-energy CT of the. The absence of parietal pleural invasion/adhesion was surgically confirmed in 13 patients, while the presence of parietal pleural invasion/adhesion was confirmed in 5 patients.

To evaluate the accuracy of four-dimensional (4D) dynamic-ventilation computed tomography (CT) scanning coupled with our novel image analysis software to diagnose parietal pleural invasion/adhesion of peripheral (subpleural) lung cancer.Įighteen patients with subpleural lung cancer underwent both 4D dynamic-ventilation CT during free breathing and conventional (static) chest CT during preoperative assessment.
