Prostate cancer remains the second leading cancer killer of men, yet it is also a disease with a high rate of overtreatment. Diffusion-weighted imaging (DWI) has shown promise as a reliable, grade-sensitive imaging method, but it is limited by low image quality. Currently, DWI quality image is directly related to low gradient amplitudes, since weak gradients must be compensated with long echo times.

前列腺MRI局部内外非线性梯度线圈扩散加权的可行性

前列腺癌仍然是男性的第二大癌症杀手，但它也是一种过度治疗率很高的疾病。扩散加权成像 (DWI) 已显示出作为一种可靠的、等级敏感的成像方法的前景，但它受到低图像质量的限制。目前，DWI 质量图像与低梯度幅度直接相关，因为弱梯度必须用长回波时间进行补偿。
