UNASSIGNED: Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is widely used in preoperative diagnosis of @entity5 . We investigated the clinical value of DCE-MRI in differential diagnosis of @entity2670 . The study involved 48 subjects with surgical pathology-confirmed @entity43 with solid components. Early dynamic phase enhancement performances of the @entity2670 in @entity1 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 @entity43 (P   <   0.05). A total of 30 @entity5 (30/31) displayed type I TIC, 8 @entity5 (8/13) showed type III TIC, and significant differences were found in TIC type between @entity2670 (P   <   0.01). @entity43 showed lower SI60 (%) and slope ratio, as well as significantly prolonged TTP20, compared to malignant @entity43 (all P   <   0.01). The microvessel count (MVC) of @entity5 was significantly higher than that of @entity5 (P   <   0.05). Receiver operating characteristic (ROC) curve analyses revealed that @entity9243 -MRI provided an optimal diagnostic performance with threshold values of SI60 at 83.40  %, TTP200 at 77.65  s, and slope ratio at 4.12. These findings revealed that @entity9243 -MRI provides critical information required for differential diagnosis of @entity2670 .
