T1ρ relaxation times in cartilage in hips with and without cam deformity

Region of interest	Cam deformity group	Control-group	p value
Entire cartilage	34 ± 4 (28–46)	32 ± 3 (27–37)	0.019*
Anterosuperior quadrant
Lateral	33 ± 5 (24–45)	29 ± 4 (22–36)	0.039*
Intermediate	33 ± 5 (23–44)	31 ± 4 (24–36)	0.150
Medial	37 ± 6 (23–50)	33 ± 4 (26–39)	0.014*
Posterosuperior quadrant
Lateral	33 ± 4 (27–41)	33 ± 4 (24–39)	0.660
Intermediate	33 ± 4 (26–48)	32 ± 7 (24–40)	0.197
Medial	34 ± 6 (20–52)	31 ± 4 (21–37)	0.039*
Ratio anterosuperior to posterosuperior quadrant
Lateral	1.00 ± 0.12 (0.77–1.33)	0.90 ± 0.15 (0.65–1.24)	0.018*
Intermediate	1.01 ± 0.14 (0.64–1.31)	1.01 ± 0.17 (0.76–1.51)	0.950
Medial	1.08 ± 0.17 (0.71–1.69)	1.06 ± 0.13 (0.89–1.35)	0.678

Values are mean ± SD with ranges in parentheses; * significant difference between hips with and without a cam deformity; T1ρ values in the entire hip cartilage in the anterosuperior and posterosuperior quadrants are in milliseconds; the quadrants are further divided in lateral, intermediate, and medial thirds.
