摘　　要：目的探讨乳腺正常腺体及肿瘤组织在常规T1WII及GRET1WII序列MRI图像质量。方法回顾分析68例已经穿刺活检或手术病理证实为乳腺癌的患者的常规T1WII和GRET1WII序列MRI图像,将ROI分别置于癌灶及正常腺体,应用配对t检验比较常规T1WII及GRET1WII图像中癌灶和正常腺体的信噪比(SNR)和对噪比(CNR)值的变化。结果常规T1WII及GRET1WII序列癌灶的SNR(61.81±7.91和56.42±8.24)与正常腺体SNR(26.41±2.36和28.91±3.11)以及图像CNR(-6.78±1.53和-6.96±1.38)的差异无统计学意义(P癌灶SNR=0.18,P正常腺体SNR=0.86,PCNR=0.34)。结论常规T1WII和GRET1WII序列MRI图像有同样的信噪比、对噪比,故在MRI乳腺检查时,可以省略常规TIW,从而缩短扫描时间。Objective To explore the imaging quality of T1WII and GRE T 1WII sequence in breast lesion and breast mammary gland MRI. Methods Sixty-eight patients with breast cancer confirmed by histopathologically were analyzed retrospectively for T1WII and GRE T1WII fingdings.The signal-to-noise （SNR） and contrast-to-nosie （CNR） were mea- sured on TI WII and GRE T1WII.A paired t-test was used to compare the differences between SNR and CNR in breast cancer and normal breast. Results There were no signifi- cant differences between SNR （61.81 ± 7.91 and 56.42 ± 8.24 for cancer, （26.41 ± 2.36 and 28.91 ± 3.11 for normal breast） and CNR（-6.78 ± 1.53 and -6.96 ± 1.38） T1WII and GRE T1WII in breast cance and normal breast. Conclusion It is possible to cancellation T1WII in the breast MRI.
