To assess the role of semiquantitative MR perfusion parameters, including wash-out rate, in differentiating benign from malignant ovarian masses, particularly focusing on their clinical implications.
Key Findings:
Significant correlation between pathological diagnosis and T2 signal intensity, ascites, and peritoneal deposits (p < 0.05).
Wash-out rate (WOR) and maximum absolute enhancement (SI max) significantly differentiated benign and malignant lesions (p < 0.05).
Cutoff value of WOR >6.03 provided accuracy of 86.2%, sensitivity of 82.4%, specificity of 90%, PPV of 93.3%, and NPV of 75%.
Cutoff value of SI max >1391.07 provided accuracy of 73.2%, sensitivity of 76.5%, specificity of 70%, PPV of 81.2%, and NPV of 63.6%.
Interpretation:
The addition of DCE MR Sequence to conventional MRI significantly enhances diagnostic accuracy for ovarian masses, with important implications for clinical practice.
Limitations:
Small sample size of 29 patients may limit the generalizability of the findings.
Exclusion of patients with simple cystic adnexal lesions or solid components <3 mm may affect the applicability of results.
Conclusion:
DCE MRI enhances the ability to differentiate malignant from benign ovarian masses, providing critical information for surgical planning and patient management.
