Abstract
Objective: This study aimed to assess and compare the diagnostic accuracy of magnetic resonance imaging (MRI) and transvaginal ultrasonography (TVUS) in identifying, mapping, and measuring uterine myomas.
Study Design:A double-blind study was conducted on 106 premenopausal women who underwent hysterectomy for benign indications. A total of 257 myomas were precisely mapped using both MRI and TVUS. The accuracy of each method in identifying myomas with confirmed pathological positions was evaluated.
Results: Both MRI and TVUS demonstrated high sensitivity (MRI: 0.99, TVUS: 0.99) and specificity (MRI: 0.86, TVUS: 0.91) in detecting the presence of myomas. However, MRI outperformed TVUS in accurately identifying the number of myomas (mean difference: 0.51 ±
1.03; P < 0.001). This difference diminished in patients with fewer myomas and smaller uterine volumes (mean difference: 0.08 ± 0.76; P = 0.60). Both MRI and TVUS showed comparable accuracy in measuring myoma diameters in patients with 1 to 4 myomas.
Conclusion: While TVUS is effective in detecting the presence of myomas, MRI offers superior accuracy in mapping their exact locations, particularly in larger uteri with multiple myomas. Our findings underscore the importance of considering both imaging modalities based on the clinical context for optimal myoma diagnosis and management
