OBJECTIVES The purpose of this study was to test the feasibility of contrast pulse sequence (CPS) ultrasound imaging for high-resolution perfusion imaging after gene transfer (GT) for therapeutic angiogenesis. BACKGROUND Imaging modalities capable of accurate and feasible perfusion measurement are essential for the preclinical and clinical development of therapeutic angiogenesis. However, cur...

OBJECTIVE To develop a study aiming at optimizing myocardial perfusion imaging. MATERIALS AND METHODS Imaging of an anthropomorphic thorax phantom with a GE SPECT Ventri gamma camera, with varied activities and acquisition times, in order to evaluate the influence of these parameters on the quality of the reconstructed medical images. The (99m)Tc-sestamibi radiotracer was utilized, and then t...
