Signal-to-nose ratio (SNR) differences between coils.

	2ch-FUS SNR	Body-RF SNR	8ch-HEAD SNR	p Value 2ch-FUS vs. body-RF	p Value 2ch-FUS vs. 8ch-HEAD	ICC (95% CI)
Reader 1	10.54 (9.05, 12.61)	2.96 (2.77, 3.31)	16.24 (13.10, 19.95)	<0.001	<0.001	0.85 (0.78, 0.89)
Reader 2	9.52 (7.74, 11.36)	2.99 (2.83, 3.26)	13.24 (10.67, 18.31)	<0.001	<0.001

Variables are expressed as median and interquartile range (25th to 75th percentile). Variables were compared using the Wilcoxon signed rank sum test. Inter-reader agreement was assessed using the intraclass correlation coefficient (ICC), with 95% confidence intervals (95% CI). Statistically significant values (p < 0.05) are highlighted in bold. Abbreviations: 2ch-FUS: Two-channel FUS-Head Coil; Body-RF: Body Radiofrequency Coil; 8ch-HEAD: Eight-channel phased-array head Coil; SNR: Signal-to-Noise Ratio; ICC: Intraclass Correlation Coefficient.
