“…Both US and MRI are equally sensitive in the evaluation of the intratumoral structure of ovarian masses, but MRI was proved more specific and accurate [39][40][41][42]. MR imaging is known to provide increased resolution for imaging of gynecologic diseases [43][44][45][46]. One of the main advantages of the technique is its efficacy in tissue characterization, allowing a confident diagnosis of dermoid cysts, most endometriomas, uterus leiomyomas and ovarian fibromas in the majority of cases [12,46].…”

The purpose was to compare the accuracy of multidetector CT (MDCT) on a 16-row CT scanner and magnetic resonance (MR) imaging in the characterization of ovarian masses. Preoperative CT examination of the abdomen and MR imaging of the pelvis was performed in 67 women, with clinically or sonographically detected adnexal masses. The CT examinations were performed on a 16-row CT scanner, and the protocol included scanning of the abdomen during the portal phase, using a detector collimation of 16 x 0.75 mm and a pitch of 1.2. We used a 1.5-T magnet unit to perform T1, T2 and fat-suppressed T1-weighted sequences, before and after intravenous administration of gadolinium chelate compounds. The accuracy of multidetector CT and MR imaging in the differentiation between benign and malignant ovarian masses was evaluated, using histopathologic results as the standard of reference. The sensitivity, specificity and accuracy of MDCT in the characterization of ovarian masses were 90.5%, 93.7% and 92.9%, respectively, and that of MR imaging 95.2%, 98.4% and 97.6%, respectively. Although MRI performed slightly better, this did not reach statistical significance. In conclusion, both MDCT on a 16-row CT scanner and MR imaging demonstrated satisfactory results in the characterization of ovarian masses.

BACKGROUND The aim of our study is to evaluate the accuracy of MR imaging in characterisation of adnexal masses. MATERIALS AND METHODS This study was done for a span of 7 months from July 2016 to January 2017. Preoperative MR imaging of the pelvis was performed in 77 women with clinically and sonographically detected adnexal masses. The accuracy of MR imaging in the differentiation between benign and malignant ovarian masses was evaluated using histopathological results as the standard of reference. RESULTS The sensitivity, specificity and accuracy of MR imaging in characterisation of ovarian masses were 95.2%, 98.4% and 97.6%, respectively. CONCLUSION In conclusion, MR imaging is a better diagnostic modality for differentiating and characterising benign and malignant adnexal masses.

“…Mit transversalen T1-gewichteten SE-Sequenzen können Uterus und Parametrien vom umgebenden Fettgewebe abgegrenzt werden [1]. Sie dienen der Gewebecharakterisierung und sind geeignet, vergrößerte Lymphknoten nachzuweisen [10,13].…”

“…Dennoch wird die MRT häufig in der klinischen Routine noch nicht zum Staging ovarieller Tumoren eingesetzt. Die Laparoskopie mit Resektion gilt weiterhin als Goldstandard in der Diagnostik von Ovarialtumoren, so dass häufig auf eine bildgebende Diagnostik verzichtet wird [3,13].…”

“…Da Fettgewebe im Gegensatz zu Blut auf fettgesättigten T1-gewichteten SE-Sequenzen einen Signalabfall zeigt [13], kann unter Verwendung von normalen und fettgesättigten T1-gewichteten Sequenzen die Diagnose des Teratoms mit einer Spezifität von 100 % gestellt werden. Ebenso können STIR-Sequenzen zur Bildgebung mit Fettsättigung eingesetzt werden.…”

Magnetic resonance imaging (MRI) is an accepted imaging method for diagnosing diseases of the female pelvis. This review article describes the role of MR imaging for the diagnosis of benign and malignant pelvic tumors. Sagittal T2-weighted fast spin echo sequences can be effectively applied to diagnose leiomyomas of the uterus and provide exact pretreatment measurements of size and localization. In the diagnostic work-up of endometrial carcinoma, fat-saturated, T1-weighted gradient echo sequences make it possible to determine precisely how deep myometrial infiltration extends and what tissue should be included in preoperative treatment planning. In cervical cancer staging, MRI permits both assessment of local tumor extent and determination of tumor volume for planning and monitoring radiotherapy. The usefulness of MRI in cervical cancer staging is, however, limited since not all early-stage cancer (FIGO stage IA and small stage IB tumors) can be detected. Hence, it appears that the use of MRI as a screening method for cervical cancer cannot be recommended. MRI can distinguish between benign and malignant ovarian tumors with high sensitivity and specificity. Standard and fat-saturated T1-weighted sequences usually can diagnose teratomas with a specificity of 100 %. Axial fat-saturated, contrast enhanced T1-weighted spin echo sequences are useful in the staging of malignant ovarian tumors since they facilitate evaluation of their internal structure and will disclose peritoneal metastases. Besides staging of ovarian cancer, MRI can be applied for localization and for monitoring treatment response.
