“…MR O-RADS scores were assigned using a modified enhancement evaluation based on postcontrast T1-weighted (T1W) images. A visual qualitative assessment compared the mass enhancement with the myometrium without the region of interest (ROI) [7,14]. The scores were assigned based on the following: (1) no adnexal mass; (2) benign mass-adnexal unilocular cyst with simple…”

Magnetic Resonance Spectroscopy for Risk Stratification of Sonographically Indeterminate Ovarian Neoplasms: Preliminary Study

et al. 2021

We aim to assess the additional value of diffusion-weighted imaging (DWI) and magnetic resonance spectroscopy (MRS) for the risk stratification of sonographically indeterminate ovarian neoplasms. A total of 21 patients with diagnosed adnexal masses between 2014 and 2017 were divided into malignant (four serous cystadenocarcinomas, four endometrioid carcinomas, three clear cell carcinomas, and one carcinosarcoma) and benign (four cystadenomas, two teratomas, one fibroma, one endometrioma, and one corpus luteal cyst) groups. An apparent diffusion coefficient (ADC) value of 1.27 × 10−3 mm2/s was considered as the optimal threshold in distinguishing malignant from benign ovarian tumors (sensitivity and specificity: 100% and 77.8%, respectively). Choline peaks were detected in six of seven O-RADS (Ovarian-Adnexal Imaging-Reporting Data System) 4 lesions and corrected all of the DWI false-negative clear cell carcinoma. Based on the presence of the choline peaks, the diagnostic performance of MRS showed a sensitivity of 77.8%, a specificity of 100%, and an accuracy of 85.7%, respectively. In conclusion, MRS could potentially play a complementary role for DWI in tumor characterization, particularly for O-RADS 4 tumors or clear cell carcinomas.

“…The accurate characterisation of an adnexal mass is essential for appropriate patient management. 13 Likely benign lesions can be managed conservatively or by laparoscopic surgery, whereas females with malignant lesions will benefit from treatment by gynaecologic oncologists or in cancer centres. 12,14 Advanced ovarian cancer usually requires radical cytoreductive surgery, followed by chemotherapy, or, alternatively, neoadjuvant chemotherapy, followed by interval debulking.…”

“…Recently, the O-RADS scoring and management system was introduced. 13,22 This 5-point risk classification system for ovarian or adnexal masses was developed in close co-operation for US and MRI by the American College of Radiology (ACR) O-RADS Committee. A standardised imaging technique and terminology should be used for risk categorisation at initial diagnosis, as well as for the follow-up.…”

“…22 US and MRI O-RADS were implemented to provide a standardised risk stratification system for ovarian and adnexal masses, which should serve as a consistent basis for analysis and reporting. 13,22 O-RADS scoring should only be used in average-risk patients with no acute symptoms. It is also aimed at providing a guidance for management of adnexal masses in clinical practice.…”

“…The integration of the risk score in the reports is ultimately intended to improve communication with referring clinicians by eliminating uncertainties in term usage and to assist in clinical decision making. 13 However, clinical management directed by the treating physician supersedes management recommendations, based on imaging alone. 13 Even in the hands of experts, 5-22% of adnexal masses will remain sonographically indeterminate or difficult to classify.…”

Ovarian cancer refers to a multitude of different cancer types originating from or involving the ovaries. Although it ranks third in gynaecological cancers, it is among the deadliest cancers in females. The prognosis mainly depends on early detection, but the majority of cases are diagnosed at advanced stages. Exact tumour delineation is crucial for individualised therapy planning. This review provides a practical update of the role of imaging in every phase throughout the course of this disease. The imaging technique of choice depends mainly on the clinical setting. Sonography remains the first-line imaging modality for cancer detection and is the most important for characterisation of adnexal masses. MRI is a valuable complementary imaging tool in sonographically indeterminate findings. For ovarian cancer staging, CT is considered an optimal imaging technique. CT renders all critical information for treatment stratification. It assists in surgery planning by displaying the load and the distribution of the disease and alerts to sites difficult to resect. It also renders critical information in selecting patients more suitable for medical therapy. In females treated for ovarian cancer, imaging is only recommended when there is suspicion of recurrence, where CT and PET/CT are most commonly used to confirm relapse and provide pivotal information for individualised treatment.

The ovarian‐adnexal reporting and data system on magnetic resonance imaging (O‐RADS MRI) score is now a well‐established tool to characterize pelvic gynecological masses based on their likelihood of malignancy. The main added value of O‐RADS MRI over O‐RADS US is to correctly reclassify lesions that were considered suspicious on US as benign on MRI. The crucial issue when characterizing an adnexal mass is to determine the presence/absence of solid tissue and thus need to perform gadolinium injection. O‐RADS MR score was built on a multivariate analysis and must be applied as a step‐by‐step analysis: 1) Is the mass an adnexal mass? 2) Is there an associated peritoneal carcinomatosis? 3) Is there any significant amount of fatty content? 4) Is there any wall enhancement? 5) Is there any internal enhancement? 6) When an internal enhancement is detected, does the internal enhancement correspond to solid tissue or not? 7) Is the solid tissue malignant? With its high value to distinguish benign from malignant adnexal masses and its high reproducibility, the O‐RADS MRI score could be a valuable tool for timely referral of a patient to an expert center for the treatment of ovarian cancers. Finally, to make a precise diagnosis allowing optimal personalized treatment, the radiologist in gynecological imaging will combine the O‐RADS MRI score with many other clinical, biological, and other MR criteria to suggest a pathological hypothesis.Level of Evidence5Technical Efficacy Stage3.
