Uptake of Tc-99m diphosphonate in a massively calcified mitral annulus: case report

In a patient with no recent myocardial insult, uptake of technetium-99m diphosphonate was noted in a region corresponding to massive calcification of the mitral annulus. The similarity of this finding to pathologic myocardial uptake is a potential source of error in the interpretation of myocardial scintigrams.
