Synthetic MRI are useful in noninvasively discriminating
low- and high-grade bladder cancer.
Figure 1 (A-D) A 58-year-old woman with low-grade BCa. (A) Axial T2-weighted image, (B-D) SyMRI-derived pseudo-colored maps (T1, T2, and PD, respectively) indicate that the mean T1, T2, and PD value are 27.27 msec, 26.18 msec, and 71.67 pu, respectively.
(E-H) A 31-year-old man with high-grade BCa. (E) Axial T2-weighted image, (F-H) SyMRI-derived pseudo-colored maps (T1, T2, and PD, respectively) indicate that the mean T1, T2, and PD value are 32.59 msec, 19.41 msec, and 71.52 pu, respectively.
Figure 2 ROC cure analysis of the mean T2 and PD values for
differentiating low- from high-grade BCa. The area under the ROC curves for the mean T2 and PD values were 0.761,
and 0.880, respectively.
