Multimodality cardiac imaging MRI-nuclear medicine

The different aspects of a protocol of MRI and nuclear medicine multimodality imaging in cardiology are presented. The aim of this work is to allow a better confrontation of these complementary informations for enhancing the clinical diagnosis. This work uses an external marking system, which is constituted by a stereotactic device. The plastic tubes in this device are filled with radioactive solution or CuSO/sub 4/. Images alignment is achieved automatically with the different steps we describe. Validation of this protocol on phantom leads to 2 mm and 2/spl deg/ precision in the alignment process.
