Abstract

Although attenuation correction (AC) has been successfully applied to large field of view (LFOV) cameras, applicability to small field of view (SFOV) cameras is a concern due to truncation. This study compared perfusion images between a LFOV and SFOV camera with truncation compensation, using the same AC solution. Seventy-eight clinically referred patients underwent rest-stress single-photon emission computed tomography (SPECT) using both a SFOV and LFOV camera in a randomized sequence. Blinded images were interpreted by a consensus of three experienced readers. The percentage of normal images for SFOV and LFOV was significantly higher with than without AC (72% vs 44% and 72% vs 49%, both P
