TABLE 3.

Comparison of T2 and T1ρ relaxation times between lesion ROIs and control ROIs

Specimen	Control T2 (ms)	Lesion T2 (ms)	T2 increase	Control T1ρ (ms)	Lesion T1ρ (ms)	T1ρ increase
4-week Humerus	70.65	89.65	26.9%	78.75	94.81	20.0%
8-week Humerus	65.21	87.22	33.7%	64.45	92.78	43.9%
12-week Humerus	67.49	71.49	5.9%	76.45	84.44	10.3%
12-week Femur	74.56	83.96	12.6%	77.39	89.34	15.4%
Mean ± SD	69.5 ± 4.1	83.1 ± 8.1	19.8 ± 12.8%	74.3 ± 6.6	90.3 ± 4.5	22.4 ± 14.9%
p-value		0.047			0.035

Note: p-values based on paired t-test between mean lesion and mean control ROI relaxation times.

Abbreviation: SD, standard deviation.
