Prediction of Early Response to Chemotherapy in Lung Cancer by Using Diffusion-Weighted MR Imaging

Table 2

Comparison of ADC values and different diameters before and after chemotherapy.

Parameters	Pretherapy	Posttherapy	𝑃
ADC (10^−3 mm^2/s)	1.22±0.19	1.76±0.47	0.000
Longest diameter (cm)	5.81±2.18	4.83±2.11	0.000
Shortest diameter (cm)	4.36±1.65	3.75±1.84	0.002

ADC: apparent diffusion coefficient.
