: Gated myocardial perfusion single-photon emission computed tomography (SPECT) has been used to non-invasively evaluate the left ventricular (LV) volume and function. This study aimed to measure the normal and range values for heart risk view-function (HRV-F) software using the Japanese Society of Nuclear Medicine Working Group (JSNM-WG) normal database and clarify the characteristics of the normal database. :We used 206 myocardial perfusion short-axis images from the normal database.

- - The study created an acrylic beads phantom to analyze texture and display uneven distributions of F-fluorodeoxyglucose (FDG) in imaging sessions of different lengths.
- - Researchers tested the phantom by capturing images of the beads in different sizes to evaluate texture features and their consistency, finding that 24 out of 31 features showed significant differences in varied conditions.
- - The findings confirmed that the acrylic beads phantom effectively illustrates heterogeneous FDG distributions, with most texture features distinguishing between homogeneous and heterogeneous distributions, except for seven specific features that showed no discriminative power.
