摘要

Background

MRI provides adequate ovarian imaging to permit accurate measurement. More normative data for children and adolescents is needed as MRI is being used for evaluation of right lower quadrant pain that could be due to ovarian torsion.

Objective

To determine normative data for ovarian size by MRI using a rapid protocol for right lower quadrant pain.

Materials and methods

Retrospective evaluation of MRI examinations of girls obtained between 2013 and 2019 was performed including chart and image review. Normative data was determined by age.

Results

Mean patient age was 12.8 years (range 1–18 years). Six hundred forty-four scans were included in the study. Thirty-three ovaries contained cysts measuring greater than 3 cm and 8 additional ovaries were torsed. These ovaries were not included in the normal ovary measurements. Patients with known or suspected polycystic ovarian syndrome or torsion also were excluded. Ovarian volumes of normal-appearing ovaries are reported by patient age.

Conclusion

Normative data for girls and adolescents utilizing a rapid MRI protocol for right lower quadrant pain is provided for increased confidence in assessing ovarian size in girls on MRI.
