What’s an optimum imaging different for pregnant girls previous to debulking surgical procedure for superior ovarian most cancers (OC)? Can whole-body magnetic resonance imaging (WB-MRI) enhance detection of detection of serosal and mesenteric involvement in girls with OC? Is chest computed tomography (CT) vital for staging of OC?
In new pointers from the European Society of Urogenital Radiology, panelists, not too long ago revealed in European Radiology, specialists from 19 establishments and 11 international locations mentioned the aforementioned questions and extra with consensus suggestions on imaging for optimum staging and follow-up in sufferers with OC.
Listed here are seven takeaways from the rule of thumb suggestions.
1. Citing the broader availability, cost-effectiveness and follow-up imaging capabilities, the panelists really useful contrast-enhanced computed tomography (CT) for evaluation of illness extent in sufferers with suspected ovarian most cancers (OC). For optimum imaging on this affected person inhabitants, the researchers emphasised acquiring the portal venous part with a multi-slice CT scanner and thorough evaluation of multiplanar reconstructions.

2. Emphasizing the impression of extra-abdominal illness upon therapy concerns for sufferers with OC, the panelists indicated that chest CT is critical to make sure full staging.
3. Previous to debulking surgical procedure in girls with superior OC, the researchers really useful CT for affected person evaluation. In circumstances involving pregnant girls or circumstances by which iodine distinction media just isn’t an choice, another imaging mixture could embrace chest CT, stomach MRI, and pelvic MRI, in keeping with the panelists.
4. Previous to the therapy of OC, the panelists really useful an stomach MRI sequence comprised of T2-weighted and T1-weighted MRI scans along with diffusion-weighted imaging (DWI) of the stomach and pelvis. They added that spasmolytic drug administration will help scale back movement artifacts and adjunctive pineapple juice could mitigate a hyper T2-weighted impact with the bowel lumen.
5. Whereas noting availability challenges and better prices with WB-MRI, the panelists maintained that the modality’s mixture of DWI and morphological sequences could facilitate enhanced detection of serosal and mesenteric involvement compared to CT and positron emission tomography-computed tomography (PET-CT).
6. The panelists famous that PET-CT could also be a viable choice for clarifying extra-abdominal findings, equivalent to extra-abdominal lymph nodes.
7. In any other case, the researchers maintained that PET-CT gives restricted worth in assessing sufferers with OC, noting challenges in diagnosing clear cell and mucinous invasive tumor subtypes in addition to a failure to detect small peritoneal metastases.
