Analyse combinée de la tomoscintigraphie myocardique et du coroscanner

Abstract : Objective : the purpose of this study was to assess the added information provided by the superimposition from the SPECT and the CT coronary angiography, in the identification of the coronary artery-related ischaemia (reversible defects) and the coronary artery-related infarction (fixed defects). Methods : 37 patients underwent myocardial SPECT and CT coronary angiography analyzed separately and then, added information provided by the fused images, in case of discordance. Results : the rates of patients showing a total concordance between SPECT and CT coronary angiography were initially 33% for the identification of the artery-related ischaemia and 81% for artery-related infarction. The use of fused images was associated with a trend toward enhancement in the identification of the ischaemia-related artery defindes at coronary angiography (overall accuracy : 74% vs 69%) but not for the infarction-related ones (overall accuracy : 95% vs 94%). Conclusions : compared with the sole analyse of SPECT, addition of fused SPECT/CT images appears to enhance the ability to identify the ischaemia-related artery but not the infarction-related ones. This might be particularly useful for determining the optimal revascularisation procedure of multivessel patients.
