Código de referência: IPL/2016/CardiaCor_ESTeSLFour groups of 71 subjects 47 with body mass index (BMI) between 30 and 35 (27 Male (M1) and 20 Female (F1)) and 24 with BMI above 35 ( 13 Male (M2) and 11 Female (F2)) who underwent stress-rest , SPECT MPI of a two day protocol, by EANM guideline protocol, with and without the incorporation of the Attenuation correction by computed tomography (CTAC), for stress and rest separately. For perfusion percentage quantifications, the 5 walls model of the left ventricle (LV) was used: anterior (ANT), lateral (LAT), inferior (INF), septal (SEP) and apical (API), using the QGS/QPSTM software. For statistical evaluation, it was used the Friedman test. Statistically significant differences were found in comparison of studies with and without attenuation correction (AC) for: F1 in stress and rest studies respectively for LAT (p=0.006 and p=0.034), INF (p=0.000 and p=0.000) and in rest study for SEP (p=0.044) LV walls; F2 group of stress and rest studies respectively for INF (p=0.001 and p=0.008) walls; M1 group of stress and rest study respectively for LAT (p=0.000 and p=0.000), INF (p=0.000 and p=0.000) SEP (p=0.003 and p=0.001) walls and just in rest study for API (p=0.045) LV walls; M2 group of stress and rest studies respectively for INF (p=0.000 and p=0.000), LAT (p=0.020 and p=0.014) and in stress study for SEP (p=0.003) LV walls. The influence of CT-AC is bigger within the groups with BMI between 30 and 35.APMTACRCIPLStakhiv, O.Melo, I.Clarke, M.Aplin, M.Singh, N.Day, K.Dizdarevic, S.Jessop, MaryamBegley, P.Carolino, ElisabeteVieira, LinaSousa, Eva2018-06-04T17:28:17Z2017-042017-04-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articleapplication/pdfhttp://hdl.handle.net/10400.21/8558engStakhiv O, Melo I, Clarke M, Carolino E, Vieira L, Sousa E, et al.
