Abstract:
Objective To investigate the correlation between MR signs of ovarian tumor torsion and D-dimer.Methods A total of 45 patients with pedicle torsion confirmed by surgery and pathology were selected as the study group,and their MR signs were analyzed.Additionally,45 patients with normal MR imaging performance were selected as the control group.Firstly,the difference of D-dimer between the study group and the control group was compared.Subsequently,the study group was classified according to the patho-logical type of ovarian tumors,tumor size,MR torsion signs and surgical treatment methods,and the difference in D-dimer among these cateegories were analyzed.Results Among the 45 cases,23 cases were located in the right pelvic cavity and 22 in the left pelvic cavity.The concordance rate of MR diagnosis was 88.9%(40/45).The primary manifestations included a turbid fat space around the tumor(38/45),twisted pedicle appearing as"banded"(20/45)and"vortex"(18/45),and localized thickening of the tumor wall on the pedicle side(31/45),etc.The difference of D-dimer between the study group and the control group was statistically significant(P<0.05).The difference of D-dimer between mesangial cyst and other types of tumors and between different surgical schemes was statistically significant(P<0.05),but there was no statistical difference between different pedicle shapes and tumor sizes(P>0.05).Conclusion MR has a high diagnostic value for the identifying the pathological types of ovarian tumors and the presence of pedicle torsion.Pre-operative D-dimer levels can indicate the presence of pedicle torsion in ovarian tumors,with ovarian cystic solid tumors more likely to exhibit increased D-dimer.
