Abstract: To investigate the early predictive value of acoustic radiation force impulse imaging (ARFI) technique in concurrent radiotherapy and chemotherapy for cervical cancer, in this study, 57 patients with cervical cancer diagnosed by pathological examination in our hospital from January 2018 to June 2019 were selected. All patients were treated with concurrent radiotherapy and chemotherapy. Before treatment, 2 weeks after treatment and at the end of treatment, the patients were examined with GE LOGIQ E9 color Doppler ultrasound diagnostic instrument. The elastic image score, strain ratio and shear wave velocity were measured and recorded. The results showed that, After concurrent chemoradiotherapy, 66.67% patients had complete remission (CR) (38/57), 33.33% patients had partial remission (PR) (19/57), no progress and stable patient. Before treatment, there were significant differences in elastic image score and shear wave velocity between CR group and PR group (P<0.05), there was no significant difference in elastic strain ratio between CR group and PR group (P>0.05). With the progress of treatment, the elastic image score,strain ratio and shear wave velocity of lesions in CR group and PR group decreased gradually. After 2 weeks of treatment and at the end of treatment, the elastic image score, strain ratio and shear wave velocity of lesions in CR group and PR group were lower than those before treatment, and CR group was lower than PR group, the difference was statistically significant (P<0.05). According to this, the elastic image score, strain ratio and shear wave velocity were continuously monitored by ARFI technique in the early stage, to reflect the effect of concurrent radiotherapy and chemotherapy for cervical cancer, it has a certain early predictive value for the efficacy of concurrent radiotherapy and chemotherapy for cervical cancer.

Key words: cervical cancer, concurrent radiotherapy and chemotherapy, acoustic radiation force impulse imaging, strain ratio, shear wave velocity
