Synopsis

Keywords: Urogenital, MR ValueMost of ovarian sex cord stromal tumors (OSCSTs) are benign with good prognosis, but low-grade malignant OSCSTs need special treatment. Correct preoperative diagnoses and accurate classification remain challenging. We retrospectively analyze the clinical and imaging characteristics of OSCSTs and found significant biomarkers such as maximum enhancement ratio (ER_max) and apparent diffusion coefficient (ADC) for the preoperative diagnosis and classification of common OSCSTs. It’s more helpful for preoperative diagnosis by combining of MRI and ultrasound together than by ultrasound alone, and MRI has the similar diagnostic accuracy as the combination.
