Transvaginal color Doppler ultrasound in diagnosis of locally advanced cervical carcinoma / 中国医师进修杂志

ABSTRACT

Objective To investigate the clinical value and sonographic features of locally advanced cervical carcinoma using transvaginal color Doppler ultrasound(TVCDU). Methods A retrospctive analysis was carried on 2-D sonograms. And color Doppler flow imaging(CDFI) in 106 cases, confirmed by pathology and surgery. Results In locally advanced cervical carcinoma, the characteristerics on TVCDU were cervical enlargment, cervical masses accompanying with uteral effusion and extracervical infiltrative masses.The rich cervical blood flow signals demonstrated as called “fireball" sign. In early cervical carcinoma,the cervix showed no apparent cervical enlargment. The blood flow signals were increased.The average RI was 0.41. Conclusions TVCDU which is very valuable in judging the infiltration extent and in differential diagnosis preoperatively can be used as a routine examination method before locally advanced cervical carcinoma treatment.
