Pelvic MRI findings altered the initial diagnosis in 17.1% of women with fibroids considered for uterine artery embolization, and MRI was more sensitive than ultrasound for adenomyosis diagnosis.

This retrospective observational study analyzed 263 women referred for uterine-artery embolization for uterine fibroids who underwent pelvic ultrasound and MRI, comparing uterine volume and fibroid measurements between modalities and evaluating agreement for diagnosing adenomyosis. MRI identified adenomyosis associated with fibroids in 43 women, whereas ultrasound indicated adenomyosis in 12, with MRI and ultrasound agreeing in 218/263 (82.9%) patients; the study also found ultrasound measured lower uterine volume than MRI and MRI detected a higher proportion of patients with multiple fibroids. The authors conclude that MRI findings revised the initial diagnosis in 17.1% of cases and that ultrasound had lower sensitivity than MRI for adenomyosis. This paper is centrally about endometriosis and/or adenomyosis — it focuses on imaging for adenomyosis in women treated with uterine-artery embolization for fibroids.

Abstract

OBJECTIVES: To assess the impact of pelvic magnetic resonance imaging (MRI) findings in the indication for uterine-artery embolization in women with fibroids, as well as the correlation between MRI and ultrasound (US) examinations for diagnosing adenomyosis. MATERIAL AND METHODS: A retrospective observational study was performed through the analysis of the medical records of 263 women referred for uterine-artery embolization as treatment for fibroids after undergoing US and MRI examinations. To compare uterine volume and fibroid measurement in US and MRI, the Wilcoxon test was used; for the number of fibroids, the McNemar test was used. The kappa coefficient was used to evaluate the correlation between US and MRI findings for diagnosing adenomyosis. RESULTS: The mean age of patients was 37.9 ± 6.8 years and 191 (72.6%) were nulliparous. Forty-three patients with adenomyosis associated with fibroid were diagnosed by MRI; US indicated the presence of adenomyosis in 12 (4.56%) women. There was agreement between MRI and US in the diagnosis of adenomyosis in 218/263 (82.9%) patients (p < 0.05). In the US examination, the mean uterine volume was lower (389 ± 340.8 cm³) than that observed in MRI (472.2 ± 415.9 cm³; p < 0.001). Regarding the number of fibroids, MRI showed a greater number of patients with multiple fibroids (68.8% vs. 57.4%, MRI and US, respectively; p < 0.001). CONCLUSIONS: In women with fibroids referred for uterine-artery embolization, MRI findings led to the revision of the initial diagnosis in 17.1% cases. US showed a lower sensitivity for diagnosing adenomyosis than MRI.
