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.
