Value of transabdominal ultrasound,transvaginal ultrasound combined with shear wave elastography in the diagnosis of cervical cancer
Objective To investigate the value of transabdominal ultrasound,transvaginal ultrasound combined with shear wave elastography in the diagnosis of cervical cancer.Method A total of 98 patients with cervical lesions were se-lected,all patients underwent transabdominal ultrasound,transvaginal ultrasound,shear wave elastography and pathologi-cal examination.Pathological examination results showed that there were 58 patients with cervical cancer,24 patients with cervical intraepithelial neoplasia(CIN),16 patients with other cervical benign lesions.The maximum and average values of elastic modulus in patients with cervical cancer,CIN and other cervical benign lesions were compared.Using the results of pathological examination as the gold standard,the diagnostic value of transabdominal ultrasound,transvagi-nal ultrasound,shear wave elastography single and combined examination in cervical cancer were analyzed.Result The maximum and average values of elastic modulus in cervical cancer patients were significantly higher than those in CIN patients and patients with other cervical benign lesions(P＜0.05).The sensitivity,specificity,accuracy,positive predictive value,and negative predictive value of transabdominal ultrasound,transvaginal ultrasound,shear wave elastography com-bined examination in diagnosing cervical cancer were 94.83％,95.00％,94.90％,96.49％,and 92.68％,respectively,high-er than those of single examination.Conclusion The combined examination of transabdominal ultrasound,transvaginal ultrasound and shear wave elastography has high diagnostic efficacy for cervical cancer.
