However, little is known about the reproducibility of MRI in the assessment of uterine fibroids. This study evaluates the inter- and intraobserver variation in the assessment of the uterine fibroids and concomitant adenomyosis in women scheduled for uterine artery embolization (UAE). Forty patients (mean age: 44.5 years) with symptomatic uterine fibroids who were scheduled for UAE underwent T1- and T2-weighted MRI. To study inter- and intraobserver agreement 40 MR images were evaluated independently by two observers and reevaluated by both observers 4 months later. Inter- and intraobserver agreement was calculated using Cohen’s κ statistic and intraclass correlation coefficient for categorical and continuous variables, respectively. Inter-observer agreement for uterine volumes (κ = 0.99, p < 0.0001), dominant fibroid volumes (κ = 0.98, p ≤ 0.0001), and number of fibroids (κ = 0.88; CI, 0.77–0.93; p < 0.0001) was excellent. For the T1- and T2-weighted signal intensity of the dominant fibroid there was good agreement between the observers (87%; 95% CI, 71.9%–95.6%) and the intraobserver agreement was good for observer A (95%; 95% CI, 83.1%–99.4%) and moderate for observer B (κ = 0.47). The interobserver agreement with respect to the presence of adenomyosis was good (κ = 0.73, p < 0.0001), while both intraobserver agreements were fair to moderate (observer A, κ = 0.55, p = 0.0003; and observer B, κ = 0.66, p < 0.0001). In conclusion, MRI criteria used for the selection of suitable UAE patients show good inter- and intraobserver reproducibility.\nSimilar content being viewed by others\nReferences\nDueholm M, Lundorf E, Hansen ES, et al.
