Motivation: Transvaginal ultrasonography (TVUS) often underestimates follicle count (FC) compared to MRI. The repeatability of FC and ovarian volume (OV) assessment was still affected by motion artifact on conventional T2-weighted fast spin echo images.
Goal(s): To propose a more reliable MRI technique in assessing the FC and OV.
Approach: High-resolution single-shot fast spin echo (SSFSE) sequence was used to accelerate the acquisition speed, and AIRTM Recon DL was used to compensate for noise in this study.
Results: Contributing to the improved time resolution and reduced noise, SSFSE-DL demonstrated better repeatability in FC and OV assessment compared to the widely used motion-robust PROPELLER technique.
Impact: High-resolution SSFSE sequence with DL reconstruction can be a reliable imaging method in the assessment of ovarian morphology. It has a potential in determining the threshold value of FC for PCOM identification in future studies.
