Quantitative myocardial perfusion SPECT/CT for the assessment of myocardial tracer uptake in patients with three-vessel coronary artery disease: Initial experiences and results.

ABSTRACT:

Background

To evaluate quantitative myocardial perfusion SPECT/CT datasets for routine clinical reporting and the assessment of myocardial tracer uptake in patients with severe TVCAD.

Methods

MPS scans were reconstructed as quantitative SPECT datasets using CTs from internal (SPECT/CT, Q_INT) and external (PET/CT, Q_EXT) sources for attenuation correction. TPD was calculated and compared to the TPD from non-quantitative SPECT datasets of the same patients. SUV_max, SUV_peak, and SUV_mean were compared between Q_INT and Q_EXT SPECT datasets. Global SUV_max and SUV_peak were compared between patients with and without TVCAD.

Results

Quantitative reconstruction was feasible. TPD showed an excellent correlation between quan
