Abstract:
Assessment of absolute myocardial hydroxydimethylene diphosphonate-technetium-99m uptake using standardized uptake value with a single-photon emission computed tomography-computed tomography cadmium zinc telluride camera (Discovery NM/CT 670CZT, GE Healthcare, Chicago, Illinois) in a patient with cardiac transthyretin-related amyloidosis treated with tafamidis showed a decrease in hydroxydimethylene diphosphonate cardiac uptake. This imaging technique should be helpful in monitoring therapy and evaluating prognosis. (Level of Difficulty: Intermediate.).
