Imaging Manifestations of Cervical Cancer on TVCDS and Its Correlation with Tumor Characteristics
Objective:To explore the imaging manifestations of cervical cancer on TVCDS(Transvaginal Color Doppler Sonography)and analyze their correlation with tumor characteristics.Methods:A retrospective analysis was conducted on the clinical data of 98 patients with cervical cancer(cervical cancer group)admit-ted to our hospital from December 2018 to November 2023.Concurrently,71 subjects with normal TVCDS re-sults during physical examinations were included as a control group.Imaging data from TVCDS examinations of both groups were collected.Comparisons were made between the groups regarding blood flow signal grading,pathological characteristics,RI(Resistance Index),PSV(Peak Systolic Velocity),and EDV(End-Dias-tolic Velocity).Spearman rank correlation analysis was used to assess the relationship between RI,PSV,EDV,and blood flow signal grading in patients with cervical cancer.Results:The RI value in the cervical cancer group was lower than that in the control group,while PSV and EDV values were higher(P<0.05).A-mong cervical cancer patients at different clinical stages,RI values were compared as follows:Stage I>StageⅡ>Stage Ⅲ.In contrast,PSV and EDV values were compared as follows:Stage I<Stage Ⅱ<Stage Ⅲ.Patients with tumor diameter<40mm and no lymph node metastasis had significantly higher RI values than those with tumor diameter≥40mm and lymph node metastasis(P<0.05).Comparisons of RI values among patients with different blood flow signal grades were as follows:Grade I>Grade Ⅱ>Grade Ⅲ.PSV and EDV values were compared as follows:Grade I<Grade Ⅱ<Grade Ⅲ(P<0.05).Correlation results indica-ted that RI was negatively correlated with blood flow signal grading(r=-0.411,P<0.001),while PSV and EDV were positively correlated with blood flow signal grading(r=0.396,0.408,P<0.001).Conclusion:Changes in RI,PSV,and EDV values on TVCDS in patients with cervical cancer are closely related to their tumor pathological characteristics and blood flow signal grading.
