Quantitative T2 values has the
potential to reliably and reproducibly differentiate prostate abnormalities,such as prostate cancer (PCa) , benign prostate hyperplasia（BPH）and normal prostate tissue (NPT). We used k-t-T2 technique to obtain the T2 maps and tested the diagnostic
performance of T2 mapping in differentiating PCa from NPT and BPH in the
peripheral zone.We found the T2 values is quite useful for cancer discrimination with,
for example, a threshold T2 of 68.3 ms yielded a sensitivity of 94% and a
specificity of 98% for PCa discrimination.
