摘要
目的:探讨磁共振动态增强乳腺VIEWS扫描及时间信号曲线结合对早期乳腺癌诊断的应用价值。方法:60例乳腺疾病患者(恶性46例,良性14例)行磁共振乳腺动态增强扫描并对病灶进行时间-信号曲线分析。结果:恶性肿瘤的动态增强形态学表现多为病灶边缘不清或呈毛刺征,形态不规则呈分叶状,内部信号不均匀或呈边缘强化,肿物邻近血管增粗、增多;时间-信号曲线多呈Ⅲ型或Ⅱ型表现。良性肿瘤形态学表现多为边缘清晰、形态规则,呈均匀或呈弥漫性、斑片样强化;时间-信号曲线表现为Ⅰ型或Ⅱ型。结论:动态增强乳腺VIEWS扫描可同时获得乳腺病变的形态学和功能学诊断信息,动态增强与时间-信号曲线联合应用,可进一步提高早期乳腺癌的MRI诊断准确性。
Objective： To investigate the application value of dynamic conwast-enhanced breast MRI VIEWS scan combined with time signal curve in the diagnosis of breast cancer. Methods： Dynamic contrast-enhanced MRI was conducted and the time signal curves of breast lesions were drawn for 60 patients with breast disease（malignant 46,benign 14）. Results： Morphologic features of malignant tumors mostly showed blurred or thin spiculate outlines, irregular shape or lobular signs, and signal heterogeneity or peripheral enhancement in dynamic contrast-enhanced MRI. Time signal curve showed type Ⅲ or Ⅱ. Morphologic features of benign tumors mostly showed clear edge, regular shape and homogeneous signal, or diffuse spot enhancement. Time signal curve showed typeI or Ⅱ Conclusion： Dynamic contrast-enhanced breast MRI VIEWS scan can get diagnosis information including morphology and function of breast lesions. The combined application of dynamic contrast-enhanced and time signal curve in MRI will greatly enhance the sensitivity of the breast cancer diagnosis.
