Figure Lengend Snippet: Study flowchart. The flowchart outlines the process of subject recruitment, data collection, and analysis for the study. POCS, polycystic ovary syndrome; MRI, magnetic resonance imaging; IVIM-DWI, intravoxel incoherent motion- diffusion weighted imaging; OA, oligo- or anovulation; HA, hyperandrogenism; PCO, polycystic ovaries.

Article Snippet: To reduce artifacts and calculation errors, an upper limit for D* was set at 170 s/mm 2 based on the settings of Siemens IVIM post-processing software.

Figure Lengend Snippet: Post-processed IVIM sequence images of a PCOS Patient. (a) Apparent diffusion coefficient (ADC) Map provides the ADC values, reflecting overall water molecule mobility and tissue microstructure. (b) f Map provides the perfusion fraction values, reflecting the microvascular density within the ovarian stroma. (c) D Map provides the true diffusion coefficient values, representing the diffusion of water molecules within the tissue. (d) D* Map provides the pseudo -diffusion coefficient values, indicating perfusion-related incoherent motion within the tissue.

Figure Lengend Snippet: Correlation heatmap between morphological parameters and functional parameters. The color intensity in the heatmap indicates the strength and direction of the correlation between the parameters. Darker colors typically represent stronger correlations, whether positive (blue) or negative (red). Asterisks on the heatmap cells denote the significance of the correlation. * p < 0.05; ** p < 0.01; *** p < 0.001. BMI, body mass index; FN, follicle counted on MRI; OV, ovarian volume calculated on MRI; FN-US: follicle count by ultrasound; ADC: apparent diffusion coefficient; D, true diffusion coefficient; D*, pseudo-diffusion coefficient; f: perfusion fraction; LH, luteinizing hormone; FSH, follicle stimulating hormone; IVIM, intravoxel incoherent motion; PCOS, polycystic ovary syndrome.
