Cardiac or chest SPECT and planar images are obtained one hour after injection of 99mTc-PYP.
If persistent blood pool activity is noted on one-hour images (e.g., renal failure), delayed images may be obtained at 3 hours.
SPECT imaging may be helpful to avoid overlap of bone uptake, distinguish blood pool activity from myocardial activity, assess the distribution of myocardial 99mTc-PYP uptake in individuals with positive planar scans, identify 99mTc-PYP uptake in the interventricular septum (commonly involved in amyloidosis) and to quantify the degree of myocardial uptake by comparison to rib uptake.
Whole body planar imaging may be helpful to identify uptake of 99mTc-PYP in the shoulder and hip girdles (a specific sign of systemic ATTR amyloidosis) and should be considered adjunctive and optional in addition to standard cardiac-centered imaging, based on local expertise.
The anterior and lateral planar images as well as the *rotating projection images* and reconstructed SPECT images are reviewed in standard cardiac imaging planes using commercial software.
Myocardial 99mTc-PYP uptake patterns are categorized as absent, focal, diffuse or focal on diffuse.
Scans with focal 99mTc-PYP uptake could represent rib fracture or previous myocardial infarction.
