Nuclear studies show benefits of progenitor cell therapy

April 11, 2008 Nuclear studies show benefits of progenitor cell therapy James Brice -------------------------------------------------------------------------------- German researchers have demonstrated the value of PET and SPECT imaging for monitoring the ability of circulating progenitor cells injected in the coronary arteries to preserve the integrity of myocardial tissue following recanalization. Twenty-six patients with occlusive coronary artery disease took part in the randomized placebo-controlled double-blinded study. FDG-PET and technetium-99m tetrofosmine-SPECT were performed about eight days after coronary interventions to image relative changes in myocardial perfusion and glucose metabolism. Segments were classified as normal, perfusion-metabolism mismatch, or scar.
