Abstract

We developed a new technique to quantitatively analyze visual evaluation single photon emission computed tomography (SPECT). Short axis tomograms and color scales were computer scanned. The scales were divided into 25 parts; numbers of each hue pixel were scored 0-100%. Short-axis images were divided into eight equal partitions, numbers of hue pixels distributed in each partition were scored, and total scores were obtained. Each partition's radio-isotope (RI) accumulation index was calculated as partition score/highest score. For method validation, scintigrams from each left ventricular phantom part were divided into eight partitions and filled with ¹²³I-BMPP (10-100%). The error between theoretical and calculated concentrations was within 20% in the concentration range of ≥50%, suggesting a good correlation and indicating the method's validity.
