^99mTc-PYP SPECT and SPECT/CT quantitation for diagnosing cardiac transthyretin amyloidosis

Molecular 99 million Tc-pyrophosphate SPECT/CT reproducibility and accuracy for diagnosing cardiac transthyretin amyloidosis, as well as SPECT/CT improved visual and quantitative results as compared to SPECT-only, as well as quantitative results. PYP SPECT/CT was reviewed for 318 patients with suspected ATTR who underwent PYP SPECT/CT. For a subgroup of the first consecutive 191 patients, SPECT-only MBP ratios and visual results were determined separately. Patients with positive myocardial uptake made up a quarter of them. MBP ratios were reliable and corresponded with visual scores u2265 2 more accurately than SPECT-only MBPs.
