Abstract:
0.05,Friedman Test).When b-value increased from 300 s/mm2 up to 500 s/mm2 and 800 s/mm2,the decreased rates of ADC value were 14% and 21% respectively in carcinous regions,5% and 11% respectively in non-carcinous regions respectively.Conclusion The ADC values are different when b-values changed in both prostatic non-carcinous and carcinous regions,but the difference of ADC between the non-carcinous and carcinous tissues seems to be stable in spite of the change of b-value(range 300-800 s/mm2).
