Mean thyroid stiffness values assessed by acoustic radiation force impulse in normal patients and in patients with diffuse thyroid pathology

	RTL (m/s)	LTL (m/s)	P value	Mean ARFI (m/s)
Normal	1.98 ± 0.37	2.01 ± 0.48	0.74 (NS)	2 ± 0.40
GD	2.62 ± 0.58	2.72 ± 0.61	0.41 (NS)	2.67 ± 0.53
CAT	2.34 ± 0.61	2.53 ± 0.68	0.20 (NS)	2.43 ± 0.58

GD: Graves’ disease; CAT: Chronic autoimmune thyroiditis; RTL: Right thyroid lobe; LTL: Left thyroid lobe; m/s: Meters/second; ARFI: Acoustic radiation force impulse; NS: Not significant.
