Aims and objectives: Cesarean section rate has been increased worldwide [1], compared with vaginal birth, cesarean section may cause more obstetric and gynecologic complications such as uterine rupture, placenta previa, endometriosis. Prior cesarean section (p-CS) scar refers to the remaining and healed scar tissue afte[...]

Methods and materials: Ethics Statement This prospective study was approved by the ethical committee of our institution. The institutional review board waived the requirement of informed volunteer consent. Information gathered on this population was performed in compliance with Health Insurance Portability and Accountabil[...]

Results: Inter observer reliability test Two scars were found in only one volunteer who underwent Cesarean section twice, both set of scar parameters were measured. The intra-class correlation coefficients range from 0.779 to 0.905, the lowest was posterior wall thickness and the highest was minimal scar thi[...]

Conclusion: 3D-SPACE MR can provide overall and detailed p-CS scar anatomy before next pregnancy, thus could assist making clinical decision. Scar shape classification was raised for further research to determine if it is related to pregnant uterine rupture.
