Imaging in Advanced Epithelial Ovarian Cancer: Assessment of Peritoneal Spread

Radiologists use CT, along with diffusion-weighted MRI and sometimes PET, to assess disease extent, including peritoneal carcinomatosis, in advanced ovarian cancer, preferably applying systematic image interpretation and disease-specific structured reporting to enhance communication and support decision-making.

Updated ESUR Guidelines for Endometrial Cancer: integrating MRI with the 2023 FIGO Staging Revolution

To summarize the key updates introduced in the 2023 International Federation of Gynecology and Obstetrics (FIGO) classification for endometrial cancer (EC), and to highlight the role of MRI in aligning with these changes for improved staging and patient management. A review of the updated 2023 FIGO classification, which integrates molecular profiling and histopathological criteria, was conducted. Additionally, the revised European Society of Urogenital Radiology (ESUR) MRI recommendations were analyzed to assess their alignment with the new FIGO framework, focusing on their role in evaluating myometrial invasion (MI) and cervical stromal involvement. The updated FIGO classification incorporates molecular data to refine risk stratification and staging accuracy. MRI continues to play a pivotal role in distinguishing between stages, mapping disease extent, and guiding surgical planning. The updated ESUR recommendations emphasize standardized MRI protocols, particularly the use of multiphase contrast-enhanced imaging, to improve diagnostic confidence in assessing MI. The integration of molecular classification into FIGO staging, supported by standardized and advanced MRI protocols as recommended by ESUR, enhances the management of endometrial cancer. Question The 2023 FIGO update integrates molecular profiling into endometrial cancer staging, requiring MRI adaptations to improve accuracy in assessing disease extent, including myometrial invasion. Findings Updated ESUR MRI guidelines emphasize multiphase contrast-enhanced imaging, structured reporting, and integration with FIGO 2023 classification, enhancing diagnostic precision for staging and treatment planning. Clinical relevance Standardized MRI protocols aligned with FIGO 2023 system improve endometrial cancer staging, guiding optimal surgical and therapeutic strategies, reducing diagnostic variability, and enhancing patient outcomes through individualized risk stratification and personalized treatment.

The BUMPy road of peritoneal metastases in ovarian cancer

Ovarian cancer is the most common cause of death due to gynecologic malignancies, with more than 70% of patients presenting with advanced stage disease at the time of diagnosis. The extent and distribution of tumor guide primary treatment selection and clinical management. While primary cytoreductive surgery with complete tumor resection improves survival, patients with extensive peritoneal disease may benefit from neoadjuvant chemotherapy first to reduce tumor burden followed by interval cytoreductive surgery. Imaging plays an essential role in triaging patients including selecting patients who may benefit from neoadjuvant chemotherapy before cytoreductive surgery. Interestingly, there are no universally established criteria to predict resectability and local practices depend on local guidelines and surgeon preferences. Nevertheless, certain anatomical tumor locations are known to be difficult to resect and are associated with suboptimal cytoreduction or require special surgical considerations. This review discusses the recent advances in the initial management of patients with ovarian cancer, a practical approach to the assessment and communication of peritoneal metastases locations on CT and MRI. It also explores recent advances in genomics profiling and radiomics that may influence the initial management of these patients.

Incidental Adnexal Lesions: CT Diagnosis and Interreader Agreement

Even among nine expert readers, CT diagnosis was not reproducible and was frequently incorrect for most adnexal lesion types, excluding dermoids, malignant ovarian lesions with metastases, and simple cysts.

Apparent diffusion coefficient analysis of solid tissue helps distinguish borderline from invasive malignant adnexal masses rated O-RADS MRI 4

The purpose of this study was to evaluate the contribution of apparent diffusion coefficient (ADC) analysis of the solid tissue of adnexal masses to optimize tumor characterization and possibly refine the risk stratification of the O-RADS MRI 4 category. The EURAD cohort was retrospectively analyzed to select all patients with an adnexal mass with solid tissue and feasible ADC measurements. Two radiologists independently measured the ADC values of solid tissue, excluding necrotic areas, surrounding structures, and magnetic susceptibility artifacts. Significant differences in diffusion quantitative parameters in the overall population and according to the morphological aspect of solid tissue were analyzed to identify its impact on ADC reliability. Receiver operating characteristics curve (ROC) was used to determine the optimum cutoff of the ADC for distinguishing invasive from non-invasive tumors in the O-RADS MRI score 4 population. The final study population included 180 women with a mean age of 57 ± 15.5 (standard deviation) years; age range: 19-95 years) with 93 benign, 23 borderline, and 137 malignant masses. The median ADC values of solid tissue was greater in borderline masses (1.310 × 10 ADC analysis of solid tissue of adnexal masses could help distinguish invasive masses within the O-RADS MRI 4 category, especially in mixed masses or those with mural nodule.
