Uptake of technetium 99m HDP in cardiac amyloidosis

We present a report and a brief summary of literature focused on a patient with suspected cardiac amyloidosis from transthoracic echocardiography and tc-99m HDP scintigraphy. Imaging demonstrated significantly increased uptake of the bone tracer within the myocardium in comparison to the highest skeletal uptake. Literature described several cases of abnormal myocardial uptake of various imaging tracers in various disease states.
