摘要

改进的定量磁共振(MR)成像技术已经发展并用于测量乳腺组织的相对含水量，T1和T2松弛时间。对两组乳腺实质表现与乳腺癌高(Dy, n=ll)和低(Nl, n= 11.1)风险相关的妇女进行测量。两组的平均相对含水量(pc0.001)和平均T1 (pcco .0001)差异显著。T2值的像素直方图显示了两组之间的显著差异，这可以用第四个矩参数来表征。额外的纹理测量，如分形维数和发育不良组织的比例，已被用于分析x射线乳房x线照片，并与MR参数进行比较。

Correlation Of Quantitative MRI Parameters With Mammographic Pattern: Risk Of Breast Cancer

Improved quantitative magnetic resonance (MR) imaging techniques have been developed and used to measure relative water content, T1 and T2 relaxation times for breast tissue. Two groups of women with mammographic parenchymal appearance associated with high (Dy, n=ll) and low (Nl, n=l 1) risk of breast cancer were measured. The two groups have significantly different average relative water content (pc0.001) and average T1 (pcO.0001). Pixel histograms of T2 values show marked differences between the two groups which can be characterized with a fourth moment parameter. Additional measures of texture such as fractal dimension and fraction of dysplastic tissue have been used to analyze the x-ray mammograms and compare with the MR parameters.
