Pelvic magnetic resonance imaging in gynecologic masses
Journal Title: Dicle Tıp Dergisi - Year 2011, Vol 38, Issue 4
Abstract
Objective: The aim of this study was to evaluate the diagnostic efficiency and the addition of the pelvic magnetic resonance imaging (MRI) to the ultrasonography (US) in adnexal and uterine masses. Materials and methods: Magnetic resonance imaging was performed to 61 patients (age 10-83 years) who refer with gynecologic mass prediagnosis. The study includes 53 patients having histopathological diagnosis and follow up results. Transvaginal, transabdominal or pelvic US were performed to all patients before or after a few days of MRI. Postoperative histopathological results and clinical and radiological follow up were used for definite diagnosis. The results verified with US and MRI findings. Results: Totally 62 pelvic lesions detected in 53 patients. Forty-two of 62 lesions (66%) were adnexal masses, 20 of 62 lesions were uterine (34%) masses, six patients had bilateral adnexal lesions and three had two different lesions in the same ovoadnexal side. Fourteen of the uterine masses were cervix cancer, four were leiomyoma, one was endometrium cancer and one vaginal cancer. Forty (40/42) adnexal masses detected in MRI, and 38 (38/42) were detected in US. Distinction between benign and malign masses was made with 80% accuracy by US and 85% accuracy by MRI. Conclusion: MRI was superior to the US in detecting the origin and the characterization of the gynecologic masses with well contrast resolution, multiplanar and multisecans imaging and detecting the soft tissue pathologies. However, US should be the first screening modality in gynecologic cases, if necessary MRI could be performed.
