Abstract:
Objective To study the enhanced performance of contrast-enhanced ultrasouond( CEUS) parametric imaging , and to explore the diagnostic value of CEUS parametric imaging in predicting extracapsular invasion and cervical lymph node metastasis of papillary thyroid cancer( PTC) . Methods One hundred and fifty-eight PTCs in 136 patients pathologically proven papillary thyroid carcinoma between January 2016 and January 2017 were enrolled in this study . According to the pathological results of extracapsular invasion and cervical lymph node metastasis respectively ,the PTCs were grouped into the negative group and the positive group . The parametric imaging features of the two groups were summarized to explore the risk factors of extracapsular invasion and cervical lymph node metastasis of PTCs respectively . Results The parametric imaging suggested that centripetal enhancement had a significant effect on extracapsular invasion ( P =0 .001) . While there was no difference in the perfusion start time of extracapsular invasion between the negative and positive group ( P > 0 .05 ) . Besides , there was no statistical significance in the perfusion start time and perfusion pattern of cervical lymph node metastasis between the negative and positive group (all P >0 .05) .Conclusions The parametric imaging features help predicting extracapsular invasion in PTCs . And the ones with centripetal enhancement patterns are more often with extracapsular invasion .
