This study compares MRI appearance of the ovary in adolescent girls with and without PCOS. Subjects were 32 girls between the ages of 12 and 19 years; 16 girls with clinical and biochemical evidence of PCOS and 16 girls without PCOS. Two radiologists independently recorded ovarian volume, follicle count per ovary, and follicle size. Average follicle count per ovary and ovarian volume were higher in PCOS subjects compared to non-PCOS subjects. MR imaging appearance of the ovary differs between adolescent girls with and without PCOS. MR imaging may help evaluate young patients in whom transvaginal ultrasound is contraindicated.
