MRI of Cesarean Scar Pregnancy:Imaging Classification and Clinical Value
摘要
Abstract
Objective:To investigate the MRI features and clinical value of cesarean scar pregnancy(CSP).Methods:The clinical and MRI data of 40 cases of CSP were retrospectively analyzed,including the MRI signal characteristics of scars,measurement of scar thickness,determination of gestational sac types,size of gestational sacs,and the relationship between gestational sacs and scars.Two doctors with different seniorities jointly observed and evaluated the MRI features of scars,gestational sacs,and the uterus,including the imaging classification of CSP,enhancement patterns,and pathological manifestations.Results:The accuracy rate of preoperative MRI in diagnosing CSP was 100%.Among the 40 cases of CSP,there were 25 cases of cystic gestational sacs and 15 cases of mass-type gestational sacs.In the MRI classification,there were 15 cases of type I,13 cases of type II,and 12 cases of type III.The coincidence rate of surgical method selection based on MRI classification was 95%.Conclusion:Preoperative MRI can accurately determine the type and size of the gestational sac in CSP,the location of the scar,and the thickness of the uterine muscle layer.Enhanced MRI is helpful in clarifying the blood supply at the scar attachment point.The MRI classification has a high coincidence rate and is of great significance for clinical decision-making.关键词
