Various long-chain fatty acids have been labeled with C-11, Cl-34m, Br-77, and I-123 and evaluated for their potential application in measuring myocardial metabolism in vivo. Comparative studies of the kinetics of accumulation and clearance from the heart muscle of mice indicate that the extraction of ..omega..-halofatty acids is more efficient than that of ..cap alpha..-halofatty acids. Among the ..omega..-halofatty acids, the highest uptake is observed for the 17-iodoheptadecanoic acid, which shows an extraction behavior almost identical to that of (I-/sup 11/C) palmitic acid, although with a higher radioactivity level in blood due to the release of free iodide.
