- W3186492270 abstract "Abstract Funding Acknowledgements Type of funding sources: None. Background Differences in spatial resolution and image filtering between the solid-state DSPECT and traditional Anger SPECT (A-SPECT) cameras are likely to result in differences in LV measurements. However, DSPECT- specific normal values have not been systematically derived. We used healthy organ-donor subjects from our high-volume solid organ transplant center for derivation of normal values. Purpose To report DSPECT-specific LV measurements normal limits derived from a unique cohort of donor subjects. Methods Subjects were 92 consecutive kidney or liver donors who underwent single day rest (5 mCi)- stress (15mCi) Tc-99m sestamibi gated SPECT myocardial perfusion imaging (MPI) on the DSPECT for pre-operative evaluation. Exclusion criteria included any cardiac disease or medications. LV measurements were made on the post-stress supine stress images using QGS®. Results Of 92 subjects (mean age 54.4 ± 15.0 and 39% men), mean EF for women and men were 77.2 ± 14.1% and 70.0 ± 14.7%, respectively. Mean end-diastolic volume for women and men were 67.0 ± 32.2 ml and 99.6 ± 51.6 ml (indexed 38.3 ± 17.2 ml/m2 and 48.1 ± 25.9 ml/m2), respectively. Mean LV wall volume for women and men were 95.9 ± 26.0 ml and 112.0 ± 48.8 ml (indexed 55.0 ± 13.8 ml/m2 and 54.1 ± 24.6 ml/m2), respectively. Conclusion We report DSPECT-specific LV measurements from normal subjects from which limits of normality can be derived for clinic use. Organ-donors who undergo pre-operative MPI are a suitable cohort for the derivation of normal values." @default.
