Abstract:
Objective To explore the value of pelvic CT angiography(CTA)digital three-dimensional reconstruction model(abbreviated as"three-dimensional model")in the diagnosis of female pelvic mass.Methods A total of 98 patients with pelvic mass who were hospitalized and operated in Xi'an People's Hos-pital(Xi'an Fourth Hospital)from January 2021 to April 2023 were selected.All patients underwent B-ultra-sound and CTA examination before operation,and the original data of CTA were collected.The digital three-dimensional model of pelvic mass was established by three-dimensional reconstruction software,and the source of pelvic mass was judged according to the blood supply of pelvic mass.Taking postoperative pathological di-agnosis as the gold standard,the coincidence rate between different preoperative diagnosis methods(B-ultra-sound,CTA examination and three-dimensional model)was compared.The receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of different preoperative diagnostic methods in judging the ovarian origin of pelvic tumors.Results A total of 130 pelvic masses were included in 98 patients,and the average maximum diameter of the mass was(71.61±3.03)mm,including 83 ovarian masses and 47 non-ovarian masses.Taking postoperative pathological diagnosis as the gold standard,the diagnostic coincidence rate of the preoperative three-dimensional model was 72.31％,which was higher than that of B-ultrasound(58.46％)and CTA(52.31％),and the differences were statistically significant(P＜0.001).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,Kappa value,and area under the ROC curve were 79.51％,91.49％,94.29％,71.67％,83.85％,0.67 and 0.855,respectively,when the three-dimensional model showed that the blood supply of the mass originated from ovarian artery or uterine artery-ovarian branch.Conclusion The three-dimensional model of pelvic CTA can directly display the blood supply source,characteristics of mass,and the relationship between mass and adjacent organs,which can guide the clinical treatment.It has certain clinical value to judge the ovarian origin of pelvic mass by using ovarian artery and uterine artery-ovarian branch.
