摘　　要：目的对比小视野和常规视野扩散加权磁共振成像在乳腺占位性病变中的应用价值。方法使用3.0T MR扫描仪对30例乳腺占位性病变的患者进行常规视野DWI(c FOV DWI)和小视野DWI(r FOV DWI)检查,对两种方法获取到图像质量进行评价;同时测量病灶的ADC值进行比较。结果 c FOV、r FOV DWI序列的图像质量评级分别为3.357±0.897、4.536±0.570,P值<0.01,有统计学意义;两种方法 DWI测量得到的ADC值在乳腺占位性病变中均无统计学意义,P值均>0.05。结论 r FOV DWI与c FOV DWI测量得到的ADC值相似,但r FOV DWI可更清晰显示乳腺占位性病变的形态、边界,提供高分辨率的弥散图像,为乳腺癌的精确诊断提供帮助。Objective To compare the reduced field-of-view diffusion weighted imaging（ r FOV DWI） and conventional diffusion weighted imaging（ c FOV DWI） in the application of neoplastic lesions of breast. Methods 30 cases of breast with neoplastic leisions were scanned with routine DWI（ c FOV DWI） and r FOV DWI,The two groups of image quality were subjective assessment; At the same time ADC values of measured lesions were compared. Results Subjective scores of image quality was significantly higher at r FOV DWI than c FOV DWI（ 4. 536 ± 0. 570 vs 3. 357 ± 0. 897,P〈0. 01）; There were no significant differences in the mean ADC values between c FOV DWI and r FOV DWI in breast lesions. Conclusion r FOV DWI can clear display the morphology and boundary of neoplastic lesions of breast,provide high-resolution diffusion images,and help the accurate diagnosis of breast cancer.
