TABLE 2.

Comparison of Image Quality: Numerical Grading

	FANSI-TGV	MEDI	L2	LADI	P
Overall image quality (IQ) grade	2.2 ± 0.5	2.1 ± 0.3	1.9 ± 0.5	2.6 ± 0.4	P < 0.05
Image sharpness (IS) grade	2 ± 0.4	2 ± 0.5	1.8 ± 0.4	2.6 ± 0.3	P < 0.05

The images were graded by three neuroradiologists (Scale 1–3; 1 = least, 3 = most) for overall image quality (IQ), image sharpness (IS). Statistical testing performed using Friedman chi-squared test. Test for multiple comparisons using Conover’s test shown in Supplementary Table S4. In all categories, LADI reconstructions were consistently scored the highest when compared to FANSI-TGV and MEDI reconstructions.
