Abstract

This study was planned to research probable differences between functional parameters of the left ventricle derived from the analysis of scans of both the multigated analysis (MUGA) and the gated blod pool single photon emission tomography (GBPS) and to present the level of correlation between calculated results. MUGA and GBPS imaging was performed to 29 patients included into the study, respectively. Scans were analyzed automatically and functional parameters including ejection fraction of the left ventricle (LVEF), peak emtying rate (PER), peak filling rate (PFR) and time-to-peak filling rate (TTPFR) were calculated. Measurements of LVEF calculated by MUGA were significantly higher than those calculated by GBPS. Besides, there was not a statistically significant difference among the other parameters including PER, PFR, TTPFR derived from both imaging modalities. When the correlation among calculated parameters was examined, it was detected that there was no significant correlation between TTPFR measurements, there was a weak-good correlation between PFR measurements and there were a statistically significant and, good correlation between PER and LVEF measuremetents. As a conclusion, there was no significant difference between functional parameters of the left ventricle that were calculated from both MUGA and GBPS, but it was detected that LVEF values calculated by GBPS were sigificantly lower. For this reason during imaging analysis, it would be helpful to cross-check the automatic analysis by manuel analysis in order to decrease the probable differences

Özet

Bu çalışma multigated analiz (MUGA) ve gated blod pool single photon emission tomography (GBPS) görüntülerin analizinden hesaplanan sol ventrikülün fonksiyonel parametreleri arasındaki olası farklılıkları araştırmak ve hesaplanan sonuçlar arasındaki ilişki düzeyini ortaya koymak için planlanmıştır. Çalışmaya dahil edilen 29 hastaya sırası ile MUGA ve GBPS görüntüleme yapıldı. Görüntüler otomatik olarak analiz edildi ve fonksiyonal parametreler olan sol ventrikül ejeksiyon fraksiyonu (LVEF), "peak emptying rate" (PER), "peak filling rate" (PFR) ve "time to peak filling rate" (TTPFR) hesaplandı. MUGA yöntemi ile hesaplanan LVEF, GBPS ile hesaplanan sonuçlara göre istatistiksel olarak anlamlı yüksek olarak bulundu. Bunun dışında her iki görüntüleme yöntemi ile hesaplanan diğer parametreler PER, PFR ve TTPFR'de istatistiksel olarak anlamlı bir fark bulunmamıştır. Hesaplanan parametreler arası korelasyon incelendiğinde, TTPFR ölçümleri arasında istatistiksel olarak anlamlı bir ilişki olmadığı, PFR ölçümleri arasında zayıf-orta düzeyde, PER ve EF ölçümleri arasında ise iyi derecede ve istatistiksel olarak anlamlı bir ilişki olduğu saptanmıştır. Sonuç olarak MUGA ve GBPS ile hesaplanan sol ventrikül diyastolik fonksiyonel parametreleri arasında anlamlı bir fark bulunmaz iken GBPS ile hesaplanan LVEF değerlerinin belirgin düşük olduğu bulunmuştur. Dolayısı ile görüntü analizi esnasında otomatik analizlerin manüel analizler ile kontrol edilmesi olası farklılıkların en aza indirilmesinde faydalı olacağı değerlendirilmektedir
