Summary

Myocardial perfusion tomoscintigraphy is a routine medicine procedure to check for the presence and severity of abnormalities of myocardial perfusion, as well as the extension of infarction residua. However, actual imagery devices (gamma cameras) have low resolution and detection sensitivity. A new semiconductor camera has 8 to 10 time higher detection sensitivity and could allow proportionally diminishing injected activities or recording times. Only one pilot study has been recently published on this type of camera, the D.SPECT camera.

This study will compare images recorded during 15 to 20 minutes by conventional cameras and 2 to 4 minutes by D.SPECT camera in patients doing tomoscintigraphy under usual conditions. The purpose is to demonstrate the equivalence of images recorded by two camera types for diagnostic information and the secondary purpose is to demonstrate the superiority of the D.SPECT camera in terms of image quality.
