Overview
This course will address advances in quantitative imaging of common female malignancies and put them in the context of clinical decision-making in an era where tumor genotyping is increasingly used. The second part of this course will address new horizons of fetal and placental imaging and address the use of quantitative metrics for better diagnostics.
Target Audience
Intermediate to advanced participants with either a MR physics or radiology background with an interest in female pelvic imaging.
Educational Objectives
As a result of attending this course, participants should be able to:
- Explain the derivation and applications of quantitative MRI in gynecological malignancy; - Explain the derivation and applications of quantitative MRI metrics in fetal and placental imaging; and - Recognize clinical decision pathways where quantitative MRI can be employed in female pelvic imaging.
13:30 | | Ovarian Cancer: Is Quantitative MRI Needed? Laure Fournier Keywords: Body: Pelvis For ovarian cancer diagnosis, the O-RADS MRI score
allows characterising the lesion as benign, borderline or malignant with very
high predictive values. Though O-RADS itself does not integrate quantitation,
quantitative imaging played a major role in establishing evidence, and more
specifically developing the visual enhancement curves. At the (mostly
peritoneal) metastatic stage, diffusion-weighted sequences have been used for
detection and quantification of the Peritoneal Cancer Index, a predictor of
resectability and survival.
Finally, conventional imaging does not currently
predict or monitor treatment response or recurrence, and more advanced
quantitative techniques such as radiomics may supply some of the answers. |
14:00 | | Endometrial Cancer: Can MRI Offer More Than a Staging Tool? Caroline Reinhold Keywords: Body: Urogenital, Body: Pelvis, Cross-organ: Cancer Magnetic resonance imaging (MRI) is considered the modality of choice for the local staging of endometrial carcinoma. The findings at MRI in combination with histopathologic findings from endometrial sampling are used for pre-operative treatment planning. However, accurate risk assessment requires information typically obtained at the time of hysterectomy including the presence of lymphovascular space invasion (LVSI), tumour grade and if available the tumour molecular classification. Quantitative analysis and radiomics of pre-operative MRI scans has the potential to noninvasively improve risk stratification and optimize management paradigms in patients with endometrial carcinoma. |
