Fig 7. T₁ and T₂ measurement plots (in ms) with zero-filled MRF and the proposed MRF-SOHO reconstructions, using 8 spokes, 1000 time points for 1mm resolution and 0.7 mm² resolution.

Analogous to the results in Fig 3, zero-filled MRF underestimated T₁, particularly at higher resolutions. A slight overestimation of T₂ was observed for the proposed approach, whereas zero-filled MRF considerably underestimated T₂ due to the higher undersampling and reduced SNR.
