ATTR Cardiac Amyloidosis: A direct comparison between conventional gamma camera heart/lung ratio quantification and D-SPECT methodology in 50 consecutive patients

Conclusions: Our single center analysis shows that the D-SPECT system is quantitively comparable to conventional gamma cameras for non-invasive diagnosis of ATTR. D-SPECT estimates of the H/CL ratio correctly identified all the positive ATTR studies performed by the standard gamma camera methodology. However, its advantages include compactness, region-centric scanning, higher sensitivity and higher resolution. In addition, due to its upright acquisition design, D-SPECT is a promising modality for patients who are unable to lie flat for conventional gamma camera systems either due to congestive heart failure or obesity.
