- W2024593585 abstract "Objectives To compare magnetic resonance and ultrasound imaging for uterine fibroid measurement. Study Design Eighteen women undergoing hysterectomy for symptomatic fibroids underwent preoperative pelvic ultrasound and magnetic resonance imaging. Resected fibroids were correlated with the images. Weighted κ agreement statistics and Spearman correlations for patient characteristics were calculated. Results Magnetic resonance imaging identified 121 of 151 pathologically confirmed fibroids, yielding 91% positive predictive value (95% confidence interval [CI], 85-95) and 80% sensitivity (95% CI, 73-86). Positive predictive value and sensitivity for ultrasound were 97% (95% CI, 89-100) and 40% (95% CI, 32-48), respectively. Mean diameter-equivalent discrepancies between imaging and pathologic measurements were 0.51 ± 0.68 cm for magnetic resonance imaging and 0.76 ± 0.88 cm for ultrasound. κ statistics comparing imaging to pathology showed better agreement for magnetic resonance than ultrasound (κ = 0.60 vs 0.36). The number of fibroids detected by magnetic resonance imaging predicted measurement errors (r = 0.76; P = .0002). Conclusion Superior sensitivity and minimal measurement discrepancies suggest magnetic resonance imaging may be preferentially used for fibroid assessment in clinical research.
