Highest % lesion enhancement

High grade serous carcinoma versus all other pathologies 0.6650.981
High grade serous carcinoma versus other invasive pathologies0.2970.457
Borderline versus invasive pathologies0.0140.040

Highest % (lesion/fat) enhancement

High grade serous carcinoma versus all other pathologies0.8130.716
High grade serous carcinoma versus other invasive pathologies0.8650.353
Borderline versus invasive pathologies0.1020.072

All other pathologies = other epithelial carcinomas + other non-epithelial cancers + borderline tumors.
Other invasive pathologies = other epithelial carcinomas + other non-epithelial cancers.
Invasive pathologies = high grade serous carcinoma + other epithelial carcinomas + other non-epithelial cancers.
P values from GEE models accounting for correlation between multiple ovarian enhancement measures from a single patient using a sandwich variance estimate. An exchangeable correlation structure was used. The log of peak percent lesion enhancement and the log of peak percent lesion/fat ratio enhancement were used in modeling.
