2D-Shear Wave Elastography in the Evaluation of Parathyroid Lesions in Patients with Hyperparathyroidism

Table 2

Mean values of 2D-SWE parameters for parathyroid and thyroid tissue, in the two groups of subjects.

Samples/variables	SWE-Mean (kPa)	SWE-Max (kPa)	SWE-SD (kPa)
Control group
RTL^a	19.6 ± 6.6	33.4 ± 9.5	4.1 ± 1.4
LTL^a	19.5 ± 6.8	33.2 ± 11.2	4.4 ± 1.7
p (RTL versus LTL)	0.92	0.91	0.29
Mean RTL-LTL^a	19.5 ± 7.6	33.4 ± 9.5	4.3 ± 1.5
Study group^a	10.2 ± 4.9	22.9 ± 10.6	4.8 ± 2.5
p (RTL versus parathyroid adenoma)	<0.001	<0.001	0.233
p (mean RTL-LTL versus parathyroid adenoma)	<0.001	<0.001	0.396

SWE: shear wave elastography; RTL: right thyroid lobe; LTL: left thyroid lobe; mean: mean value; max: maximum value; SD: standard deviation; ^avalues expressed as mean ± standard deviation.
