动态增强磁共振成像（DCE-MRI）广泛应用于各种肿瘤的术前诊断。目的探讨MRI动态增强扫描在卵巢良恶性病变鉴别诊断中的临床价值。该研究涉及48名手术病理证实的卵巢肿瘤实体成分的受试者。评价患者卵巢病变的早期动态增强表现，包括增强模式、时间-信号强度曲线（TIC）、初始60 s信号强度率（SI 60）、200 s内达峰时间（TTP 200）和斜率比。卵巢良、恶性肿瘤的强化模式差异有显著性（P
Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely used in preoperative diagnosis of various tumors. We investigated the clinical value of DCE-MRI in differential diagnosis of malignant and benign ovarian lesions. The study involved 48 subjects with surgical pathology-confirmed ovarian tumors with solid components. Early dynamic phase enhancement performances of the ovarian lesions in patients were assessed, including the enhancement pattern, time-signal intensity curve (TIC), signal intensity rate at the initial 60 s (SI60), time to peak within 200 s (TTP200), and slope ratio. There were significant differences in enhancement patterns between benign and malignant ovarian tumors (P
