title: Low uptake of Tc-99m tetrofosmin in lung cancer: a case report.
abstract: Technetium-99m tetrofosmin has been used as a tumor-imaging agent in cases of lung cancer. The authors present a case showing a lung tumor that concentrated Tl-201 distinctly more than Tc-99m tetrofosmin during a dual-isotope cardiac examination. A brief review of the literature is provided and possible explanations for this difference in tracer uptake are discussed.
