  1. Absolute differences are presented as mean ± standard deviation, with 95% confidence intervals in parentheses. Comparisons were conducted using paired t tests, and results with P-values below 0.05 were emphasized in bold. FNPO follicle number per ovary, SSFSE-C single-shot fast spin-echo acquisition using conventional reconstruction, SSFSE-DL single-shot fast spin-echo acquisition using deep learning reconstruction, PROPELLER periodically rotated overlapping parallel lines with enhanced reconstruction; *Statistically significant between the intra-observer and inter-observer absolute differences. Significant values are in bold.
