进展期NSCLC的CTP可重复性检验（n=14）
The reproducibility of advanced NSCLC at CTP examination (n=14)
| CTP | Mean±SD | Mean difference* | WCV | RC (%) | ICC |
| CTP: CT perfusion; WCV: within subject coefficient of variation; RC: repeatability coefficient; ICC: intraclass correlation coefficient; BF: blood flow; BV: blood volume; MTT: mean transit time; PS; permeability surface area product. *Mean difference-the average of difference between two measures of CTP parameters; Data in parentheses are 95% limits of agreement. | |||||
