Table 3. Comparison of quantitative TIC parameters between thyroid inflammatory nodules and papillary carcinoma.

Parameters Inflammatory nodules Papillary carcinoma P value
PI 55.42 (45.41, 76.91) 84.43 (74.93, 90.92) <0.001*
RT (s) 4.76 (4.01, 7.05) 6.07 (3.88, 8.20) 0.307
TTP (s) 6.24 (4.63, 8.12) 6.57 (4.34, 9.81) 0.515
AS 22.39 (13.37, 29.93) 29.54 (19.37, 44.77) 0.013*
DS −3.53 (−6.65, −2.00) −2.98 (−7.65, −2.15) 0.773

The data was presented as median (interquartile range). *P<0.05 were considered as significant difference. TIC, time-intensity curve; PI, peak intensity; RT, rise time; TTP, time to peak; AS, the maximum slope rate of ascending curve; DS, the maximum slope rate of descending curve.
