[Abstract]:Objective: To explore the diagnostic value of three-dimensional power Doppler ultrasound and ultrasound elastography in cervical cancer, and compare the advantages of the two methods.
Data and methods: the subjects included the cervical cancer patients group (40 lesions), CIN patients group (25 lesions) and normal control group (20 healthy volunteers). The patients were used the logic E9 ultrasonic diagnostic instrument of GE company before operation, with three-dimensional energy Doppler technique and ultrasound elastography, the vaginal probe was selected, and the patient's emptying bladder was asked to check. Taking the cystotomy position, the probe was slowly placed in the posterior fornix of the vagina, transversely, longitudinally and multi azimuthal and multi angle scanning. The cervical morphology, size, internal echoes, cervical mucosa and some vagina conditions were observed in the two-dimensional ultrasound mode. The conditions of the cervix and the internal and peripheral blood flow of the cervix were observed at the same time. The dynamic characteristics, and the distribution of blood vessels. Then switch to the elastic imaging mode for real-time elastic imaging of the cervix, and the women in the health examination have an elastic imaging examination of the whole cervix.
According to the 5 grade scoring method proposed by Thomas, the cervical elastography images of cervical cancer patients, CIN patients and normal control groups were analyzed, and the value of image elasticity score was obtained. Then the three-dimensional energy Doppler program was switched to the three-dimensional energy Doppler program, and the three dimensional histogram was automatically obtained by the computer program method of the VOCAL system, and the tumor blood flow parameters VI, FI, VFI were obtained. Women in health examination measured the blood flow parameters of the whole cervix VI, FI, and VFI. to explore the difference between the elastic image scores between the patients with cervical cancer, the CIN group and the normal control group. The statistical analysis of the three dimensional energy Doppler blood flow parameters of the cervical cancer group, the CIN group and the normal control group was VI, FI, VFI, and the difference was obtained by the ROC curve when there was a difference. Finally, the accuracy, sensitivity, specificity and diagnostic value of conventional two-dimensional ultrasound, three-dimensional energy Doppler ultrasound and ultrasound elastography in the diagnosis of cervical cancer were compared.
