MRI
MRI is the modality of choice in the characterisation of ovarian malignancy and in the detection of lymphatic, peritoneal, and distant metastases, both for preoperative planning and post treatment follow up.
The cystic components are high T2, low T1 signal, unless there has been intralesional haemorrage (c.f. mucinous cystadenocarcinoma, where there is typically slightly increased T1 signal of the cystic component)
Solid malignant components demonstrate intermediate T1 and T2 signal, restricted diffusion, and gadolinium enhancement.
DWI is useful for detection of distant metastases.
