Ultrashort echo time (UTE) T2* images of 20 sacroiliac joints were acquired in 10 asymptomatic volunteers. Each sacroiliac (SI) joint was segmented manually and divided into thirds (superior, middle, and inferior). Differences in mean UTE T2* values were assessed. Results demonstrated a mean UTE T2* value of 10.38 ± 0.62 ms in the SI joints. There was no statistical significance between right and left sides (p = 0.89), superior, middle, and inferior third regions (p = 0.86), or males and females (p = 0.47). Intra-observer variability with ICC ranged from 0.89-0.98.
