目的 对比研究乳腺常规视野单次激发平面回波扩散加权成像(SS-EPI DWI)和2组小视野扩散加权成像(rFOV DWI)应用价值.方法 回顾分析2012年8月-2013年5月浙江省宁波市医疗中心李惠利医院78例乳腺受检者(68例正常乳腺,10例乳腺癌),分别行SS-EPI(FOV360 mm ×360 mm)、rFOV1 (FOV 360 mm×180 mm)和rFOV2(FOV 280 mm×140 mm) DWI检查.比较3组图像质量、ADC值,2组rFOV DWI的信噪比(SNR).结果 78例rFOV DWI1图像质量评级为4.74,SS-EPIDWI为3.59,rFOV DWI2为3.55.68例正常乳腺SS-EPI DWI平均ADC值1.832×10-3mm2/s,rFOV DWI1为1.701×10-3mm2/s,rFOV DWI2为1.615×10-3mm2/s;10例乳腺癌SS-EPIDWI为1.345×10-3 mm2/s,rFOV DWI1为1.220×10-3 mm2/s,rFOV DWI2为1.149×10-3mm2/s.rFOV DWI2的SNR低于rFOV DWI1.结论 适宜的rFOV DWI图像质量高、变形小,可以在乳腺疾病诊断中发挥重要作用.

Objective To compare the application value between reduced field-of-view diffusion weighted imaging (rFOV DWI) and single-shot echo-planar-imaging diffusion weighted imaging (SS-EPI DWI) of the breast.Methods 78 cases(68 normal breast,10 breast cancer) were canned with SS-EPI DWI (FOV 360 mm × 360 mm),rFOV DWI1 (FOV 360 mm × 180 mm) and rFOV DWI2 (FOV 280 mm × 140 mm).Image quality and ADC values of breast were compared with three groups.SNR were compared with rFOV DWI1 and rFOV DWI2.Results The image quality score of 78 cases was 4.74 by rFOV DWI1,3.59 by SS-EPI DWI and 3.55 by rFOV DWI2.The mean ADC value of 68 normal breast was 1.832 × 10-3 mm2/s by SS-EPI DWI,1.701 × 10-3mm2/s by rFOV DWI1 and 1.615 × 10-3mm2/s by rFOV DWI2.The mean ADC value of 10 breast cancer was 1.345 × 10-3mm2/s by SS-EPI DWI,1.220 × 10-3mm2/s by rFOV DWI1 and 1.149 × 10-3 mm2/s by rFOV DWI2.SNR of rFOV DWI1 images was much higher than FOV DWI2.Conclusion Sizeable rFOV DWI has higher resolution,less distortion than SS-EPI DWI,rFOV DWI will be useful in the diagnosis of the breast diseases.
