CTICasesTransthyretin cardiac amyloidosis (ATTR amyloidosis) on bone scan
Imaging findings
Technetium bone scan shows intense, diffuse myocardial radiotracer uptake (greater than bone). Biopsy confirmed ATTR amyloidosis.
Key takeaways
Bone-seeking radiotracers (such as Technetium-99m pyrophosphate or oxidronate) accumulate in the myocardium of patients with ATTR amyloidosis. This non-invasive test is highly specific for differentiating ATTR from AL amyloidosis.
