The average ADC, relative ADC (rADC) and the ADC from center to periphery of the lesion were calculated.
测定各期病灶平均表观扩散系数值、相对表观扩散系数值及中心-边缘表观扩散系数值。
The rADC in hyperacute and acute stage of focus center was minimized, and increased progressively from center to periphery with gradient sign.
超急性、急性期病灶中心相对表观扩散系数最低，从中心往外逐渐升高呈梯度征。
The rADC in hyperacute and acute stage of focus center was minimized, and increased progressively from center to periphery with gradient sign.
超急性、急性期病灶中心相对表观扩散系数最低，从中心往外逐渐升高呈梯度征。
