乳腺腺肌上皮瘤一例影像学表现及文献复习
Journal of Clinical Radiology(2014)
Abstract
患者 女,42岁.乳腺筛查X线发现右乳结节伴微钙化.体检:双乳对称,乳头无凹陷、溢液,乳房皮肤未见异常,未扪及包块,腋窝、锁骨上、下淋巴结无肿大.
影像检查:X线采用GESenographe DS全视野数字系统乳腺机,常规摄取头尾位(CC)、内外侧斜位(MLO),并加照局部点压片及侧位(ML);MRI采用Siemens1.5 T Avanto磁共振扫描仪,4通道乳腺专用线圈.患者取俯卧位,双乳自然下垂,平扫采用快速自旋回波T1WI、T2WI脂肪抑制横轴位及矢状位;层厚1.7 mm,层间距0.34 mm,矩阵448×336;扩散加权成像(diffusin weigh ima-ging,DWI)采用单次激发自旋平面回波序列,扩散敏感度(b)值取800 s/mm2;动态增强由高压注射器经手背静脉以团注方式注入对比剂Gd-DTPA,剂量为0.15mmol/kg体重,流率3 ml/s,并同时注射等量生理盐水,即刻进行扫描,连续采集6个时相,单期扫描时间为60 s.彩色超声检查仪器型号为Sequoia512.
