[Problem]
Provided is a labeled fatty acid derivative for diagnostic imaging that enables quantification of fatty acid metabolic activity in the heart muscle.
[Means for Solution]
The present inventors have conducted intensive investigations on a method that enables quantification of fatty acid metabolic activity and thus have found that a labeled fatty acid derivative typified by 3-[(5Z)-3-[18F]fluorotetradeca-5-en-1-yl]sulfanyl}propanoic acid or a salt thereof has excellent accumulation to the heart muscle and thus enables imaging of fatty acid metabolic activity by positron emission tomography (PET). Therefore, the labeled fatty acid derivative of the present invention can be used as a radiolabeled tracer for rapid and non-invasive quantification of fatty acid metabolic activity in the heart muscle, diagnostic imaging of heart disease typified by an ischemic heart disease, diagnostic imaging of the therapeutic effect of a therapeutic drug for heart disease, and the like.
