Clinical Trial Summary

Tomographic radionuclide angiography (or blood pool) is a reproducible method to evaluate left ventricular ejection fraction that is needed during oncological treatments or to evaluate cardiopathies. Cardiac-dedicated CZT systems allowed dose or time reduction. Multipurpose CZT cameras have not yet been evaluated in this indication. Moreover, the impact of attenuation correction is not known.


Clinical Trial Description

Tomographic radionuclide angiography is a simple, rapid and reproducible method of cardiac function measurement, including left (LVEF) and right (RVEF) ventricular ejection fractions. In addition to cardiological indications, this examination is often performed as part of cardiac toxicity screening during the various oncological treatments. This indication is all the more true since the arrival of CZT gamma cameras dedicated to cardiological studies has made it possible to reduce injected activities, as well as examination times. The multipurpose CZT camera allows tomoscintigraphic acquisitions to be carried out using CZT technology as well. Unlike the CZT gamma cameras dedicated to cardiological studies, this system can be used for the exploration of different organs, and also allows the realization of CT slices for attenuation correction. Patients included in this study will be double scanned both on a dedicated cardiac CZT camera and on multipurpose CZT camera, with CT. LVEF and RVEF will be then compared. ;
