Abstract
Aims: To assess the impact of attenuation correction in reducing artifacts and the influence of gender and body mass on the effect of attenuation correction.

Methods: 102 patients referred for myocardial perfusion imaging (mean age: 53.24 ± 12.7) were enrolled. They all underwent stress (dynamic or pharmaceutical) and rest Tc-99m MIBI studies. Polar maps of the left ventricular cavity with 17 segments of both the noncorrected (NC) and attenuation corrected (AC) images were generated and semiquantitatively analyzed by software automatically.

Results: Segmental scores in inferior wall were significantly low (p < 0.05) particularly in male population irrespective of BMI. AC didn't do significant impact in score values in anterior wall of female population (p > 0.05). AC also generated artifactual perfusion defects in apex and apical segments (p < 0.05).

Conclusion: This study demonstrates that Attenuation correction using hybrid SPECT-CT improved average myocardial perfusion uptake in inferior regions and this technique is more beneficial to male populace.
